Hi, I have this G&P M14 DMR, and yesterday it wouldn't shoot. I figured out that the contacts had too much black grease on them (terrible gunk) so I wiped it off and applied a little bit of cylinder grease for reduced friction. However, the hopup was plastic, so I started to think, what could make this gun better. Here's My list (open to comments):

Initial Upgrades:
2G bucking (or scs with stock bucking?)
Prometheus 650mm barrel
Bore Up set (which one?)
New Hopup?
maybe deans and mosfet

Later on:
m140 spring
Prometheus air nozzle
G&P m160 motor
Firefly Hard bucking

Remember, this is a G&P which usually makes the best pistons/p-heads, so that (as well as the gears) should be fine. I use .25 G&Gs and I don't know if the barrel trully will matter since G&P has great quality and since the bucking is upgraded. And by the way, the 650mm barrel can fit since the flashhider is large (perfect length for 650mm, perhaps intentionally). Thank you and God Bless!

Did you put cylinder grease on your contacts? If so, remove it ASAP. Unless it's dielectric grease, it will burn up on your contacts. (doing more harm than good)

2G or SCS-SCS is cheaper and works very well. I would rather add a SCS since it's cheaper. Either one should work very well. A new bucking is always a good idea though. So basically 2G vs Systema/Guarder+SCS

Don't get that long of a barrel, it won't have really any increase in performance. If you decide the SCS doesn't give you the accuracy you want, then get a Prometheus barrel that matches your original barrel length. (or close to it) If you are building a DMR (which it sounds like you are), get the Prometheus barrel right away.

You won't need the bore up kit anymore if you do what I say. :)

Deans and mosfet are always a great idea.

Later on
Get a Guarder SP130
You shouldn't need the air nozzle
Good choice
Keep the 2G bucking or SCS combo

G&P armalites always seem to have their gears break fairly quickly. Hopefully the M14 doesn't suffer from this problem, but I would replace them with Guarder gears to be safe.

Thanx, and should I use gear grease on them, or no grease at all.

No grease at all on the contacts, unless it is dielectric. Regular grease will burn from the sparks and I believe it actually makes arcing worse. Dielectric grease slows down arcing apparently. (I'm not very knowledgeable with the electrical stuff, so hopefully someone can explain it better or correctly.....lol)

Contacts don't need to be lubricated since there is little friction.

You should do a review on this gun, little info is known about it.

I will

You said G&G .25g BBs, are they the regular G&G or the G&G bio BBs? (the bios are much better).
What kind of ranged accuracy do you get with the stock AEG?
When you say "better", what exactly are you looking to achieve?
What is your local field limits for muzzle velocity and engagement?

There will be no advantage going to a longer barrel/bore up kit or changing the air nozzle.
The G&P M14 is 100% TM clone. G&P Armalite hop up units are quite good their M14 unit should be as well.
G&P internals are excellent except for their gears, which should be changed at some point.

Stock G&P barrels are very good but a good aftermarket tightbore barrel would shoot better.
The lip on a G&P hop up bucking is a little thicker then a TM/Systema bucking and needs to be changed.

Putting a MOSFET switch, Deans connectors and soldering all possible connections, is one of the best upgrades that can be done to any AEG.

First, I recommend you put in a Prometheus or Madbull 6.03mm x 500mm inner barrel. Make sure you get one specifically cut for a TM M14.
Put in a regular, Systema soft bucking. To fit it in a TM M14, you have to cut about 1/4" - 3/8" off the back, it's the same otherwise.
Use the stock G&P nub. I have the stock nub in my M14 and it shoots pretty good (see below).

All G&P Armalite replicas come with a 12g piston weight, the G&P M14 should also. When you put the 6.03mm barrel in the gun, the presence of the weight is going to give the gun a big muzzle velocity boost. In my son's G&P M16, it was over 30fps. See how the gun shoots with just a new barrel and bucking. I'm betting it will be impressive. You can always put in a conical or H nub later if you want. At least you have a baseline to judge it against. Keep in mind that a new hop up bucking takes at least a thousand rounds to break in.

If you choose to make the gun shoot harder at some point, get the spring of your choice (M140?). Get Prometheus double torque gears, they are helical but use a standard, full tooth piston. G&P M160 or Guarder Infinite Torque-Up motor (short). I wanted the G&P M160 motor for my gun, but I could not get a short one at the time, so I got the Guarder motor instead, which works very good.

G&P gears are problematic. The gear shafts in my son's G&P M4 failed after 29,000 rounds. Some people have reported they break much quicker. If you are going to put a harder spring in the gun, you will be changing the gears anyway, so it won't matter. If you don't, be aware that at some point there is a good probability one or more of the gear shafts is going to fail.

I have a TM M14 with a Prometheus 6.03 barrel, the stock TM hop up unit, stock TM bucking (same as the Systema soft with 3/8" cut off) the stock TM hop up nub and a custom 12g piston weight.
As an assault rifle, with an M120 spring (420fps w/ .20g BB, shooting 385fps w/ TM .25g BBs), it could hit a man sized target 10 hits out of 10 shots at 225 feet, about a 12" grouping.
As a sniper rifle, with an M150 spring (520fps w/ .20g BB, shooting 450fps w/ Maruzen .29g BBs), Prometheus double torque gears and a Guarder Infinite Torque-Up motor, it can hit a man sized target 9 hits out of 10 shots at 275 feet.

Good luck.

Thanx man! And I found the m160 that will fit http://shop.ehobbyasia.com/upgrade-part/pa...ng-for-aeg.html Also, how would a kwa 2g bucking be, since I have an extra. And I want to make it a sniper. O and why are the bios better?

I have heard very good things about the 2G bucking, but I'd get the Systema ($7, come on!) and compare results. Whichever you use, you'll have an extra bucking if the other one rips or wears out.

Yep, that's the best motor for your money right there.

I've not used the plastic G&G's, but their bios are great. Goldenball and Bioval are also excellent. I would follow Namloot's lead a far as upgrades go; those are excellent suggestions.

This post has been edited by Hardaway: Oct 31 2009, 01:52 PM

Yea, I'll try both. But will a Prometheus nozzle inprove the fps? And I got the KWA bucking for only 14 from asgi, so the price is not an issue anymore. But would Systema gears be ok as well. And hows this for a list:

M160 motor
Prometheus 550mm barrel
Prometheus air nozzle
2G bucking or scs and systema
Guarder sp150
mosfet (which brand?)
sorbo?
new wiring (contacts are really bad)
Systema gears?

For the gears, I have some systemas, so I'll see if they fit. Any comments? and is prommy wiring best or will 16awg king arms do the trick?

This post has been edited by bullpupfan: Nov 3 2009, 12:46 PM

I would say go for the Prommy gears over the Systema. I have heard nothing but amazing things about them. The Systemas sound solid as well but I've also heard a few bad stories abot them. I would assume those are rare cases though so you probably be fine with either but for me I'd go Prommy. Also you might want to have a piston on deck just in case yours goes out. Maybe a Supercore or a G&G Co-Alloy. Something like that but its up to you really.

thanx! heres the new list:

M160 motor
Prometheus 550mm barrel
Prometheus air nozzle
2G bucking?
Guarder sp150?
AB long mosfet
sorbo
extra Prometheus wiring
Systema gears

so is the 2g good and is the sp150 too high/low?

TPE padding works better than sorbothane. Check that stuff out.

Edit: And why are you still getting systema gears? They're good, but Prometheus are a far cry better.

This post has been edited by p4ndora: Nov 4 2009, 02:20 AM

Personally, I would go with Guarder gears. However, if you are going to spend that much on Systemas, you might as well spend a bit more and get the Promy set. Everyone seems to rave about those things.

This post has been edited by Stealthmaster14: Nov 4 2009, 02:54 AM

Looks good but yea, if you have some extra $$$, get a prommy gear set.
Just remember that for the barrel, get the one for the m14 because they have a different cut from other barrels. Some dude at evike tried selling me a 500mm Barrel for m14s when I said I needed a 509mm Barrel for m16s. If I hadnt double checked that he got the wrong one, then I would have been screwed.

What optic are u using?

I have extra systema gears but idk if they fit, so ill check. whats so bad about the g&p gears anyway? and what barrel would fit since I wanted to use a 550mm? And I'm using the original scope. And would element gears be good since all they have to do is not break? Lastly, why is tpe better (and I don't care about sound)?

Why are TPE pads better?

This post has been edited by bullpupfan: Nov 4 2009, 10:20 PM

-how long can the g&p gears last?
-and what barrel would fit since I wanted to use a 550mm?
-So what about these gears: http://shop.ehobbyasia.com/upgrade-part/pa...m14-series.html or would rof be better with prommy's?

Hearsay?

I've used a supercore and it SUCKED. it had really bad fitment in my TM shell (hey, most upgrade parts are designed off of TM shells...), and caused the whole thing to jam up. after sanding everything down, there was no improvement.

http://www.airsoftforum.com/board/Supercor...0#entry18163340

and I wasn't the only one to have that issue either.



PM Maruipro, he has a G&G reinforced piston on his DMR and supposedly it's gone through 100k rounds with little wear.



KK21

Supercores are really over rated. G&G, G&P, and KWA all make amazing pistons. For piston heads, has anyone used the POMs?

Yup, I have a G&G reinforced piston (the one with 4 metal teeth) in my DMR and it has gone thought a bit over 100k and going strong.

I also had a G&G piston in my AEG defender shooting 28RPS for roughly 35k.

Im also going to get another G&G piston for project magpul.





I have a prometheus POM piston head in my DMR. Nothing that special from systema duracons.

Hows the list??? I need to find out which parts to get since I'm ordering soon. Also, I have some questions.

1- Why is TPE better?
2- Should I get a higher or lower spring than an sp150 (or stay with this spring)?
3-How long can the G&P gears last?
4-What barrel would fit since I wanted to use a 550mm?
5-So what about these gears: http://shop.ehobbyasia.com/upgrade-part/pa...m14-series.html or would rof be better with prommy's or even element's?

Heres the list:

G&P M160 motor
Prometheus 550mm barrel
Prometheus air nozzle
SCS and systema bucking
Guarder sp150
Extreme fire, AB long
Sorbo set
New Prometheus wiring
Guarder gears
New G&P contacts (contacts are really bad)

Thank you!!!

Will those Guarder gears hold up an SP150? I also have a G&P M14 that I will be upgrading to DMR status soon, so I am also searching for gears that'll be able to support a high-power spring. I wanted to buy Prommy gears, but the strongest V7 gears they have are Double Torque which supposedly should only be used with up to an M120 (or equivalent) spring. Plus, they are almost $100. What is the difference between V7 gears and V2/V3 gears, anyways?

The spur gear is smaller to fit into a smaller gearbox.

so I can get a guarder replacement spur gear and use my systema v2/3 gears or would the g&p be fine? What spring tho?

Thank you!!!

I'm just as interested in the upgrading of this gun to DMR status as bullpup, so I'll bump this on up.

On topic: If you put a 2G bucking, wouldn't that prevent you from using an SCS? Wouldn't a Prommy hard type be a better choice?

Yes it has built in scs (so to speak), but the prommy hard type would work well with an scs but hard bucking may not bend as easily as normal bucking and therefore wouldn't make the "curve" like a soft bucking with the scs. I don't know much about hard buckings though.

No, it's a finned bucking. It really isn't even close to the SCS lol.


Hard buckings seem to be kinda iffy. I would use the 2G or the Systema+SCS.

Oh thanx, but do you have any criticisms for the list (or answers for the questions)? And how do they differ (SCS and 2g)

I'm most likely going to go with a Systema bucking plus SCS. While I'm at it, I might as well post my upgrade list so that I can get some comments/criticism/etc.

Accuracy stuffz:
-Systema bucking
-SCS
-Prometheus M14 inner barrel OR EdGi M14 inner barrel (advice?)

POWER!!! and compression:
-Gears: not sure, advice?
-Piston: Systema Aluminum Piston, will it fit?, advice?
-Piston Head: Systema Aluminum Piston Head, will it fit?, advice? OR stock
-Cylinder: Systema Bore Up Type 0 Cylinder, will it fit?, advice? OR stock
-Cylinder Head: Prometheus v7 Aero Cylinder Head OR Guarder v7 Cylinder Head OR stock
-Motor: G&P M14 M160 motor
-Shell: stock
-Spring: M140
-Spring Guide: stock, advice?
-Air nozzle: stock, advice?

Other:
-Professionally shimmed, what shims?
-Wiring: stock
-MOSFET: not sure, advice?

Prometheus if possible. Otherwise, Guarder should be fine.
Don't get an aluminum piston, stick with the stock piston until it breaks. Then get one of those G&G reinforced ones.
Keep the stock compression parts. Maybe add a new O ring though

Motor is fine

Guarder SP130

Keep the stock nozzle

G&P shims

Add deans (I think G&Ps come with them though)

AWS supposedly makes great ones.

Let me answer your question...

The SCS is totally different from the 2G Bucking since it is a nub (made from engineering plastic). The SCS doesn't get "squished" like normal nubs do and it will always retain its concavity. The SCS is best suited for soft type buckings like Systema, Guarder, Madbull, Prometheus, etc.

The KWA 2G bucking on the other hand needs a soft rubber nub so that the fins inside the bucking can spread out. If you use the SCS on the 2G bucking, the spread of the fins will get affected especially the 2 fins in the middle since it will bend in the middle causing the 2 fins to close up together.

I would suggest that you get an SP140 (530 fps @ .2 gram bbs) instead of the SP150. I've seen bbs embedded on faces, arms and necks using an SP150 and it is horrible to look at...

Why SP130? Is that good enough to be a DMR? Also, what kind of gears should I get? And yes, G&Ps come with deans. And doesn't it already have G&P shims since its a G&P?

Also, when you said "Prometheus if possible. Otherwise, Guarder should be fine," were you referring to the cylinder head? If so, didn't you say that I shouldn't replace the compression stuff?

And will any piston and p-head work in a v7 GB?

By the way, I don't want this being a budget DMR. I want to have a full-blown DMR. I'm not too worried about money. Worse comes to worse, I'll just slowly buy everything I need.

SP130=M140. I meant the gears. Get Prometheus gears, they are supposed to be pretty much the best. (excluding RC gears or whatever they are called).

Get your parts from ehobbyasia.com
If money is no object:
Guarder SP130
#14 O ring
Systema non bearing Duracon PH
Prometheus gears-IDK what kind you will need (double torque and what not)
Prometheus barrel (if you really want to, you could get a PDI, don't think it's worth it though)
KWA 2G bucking
Systema bucking
SCS (get both and see which work best)
G&P M160 motor
Elite battery pack (idk what voltage you want? You will probably want a 10.8v though) cheapbatterypacks.com
MOSFET (depends on what features you want)
Reshim/regrease (use G&P shims, you will need a shim kit)
Several different bb brands and weights to see which work best. (I've found Goldenball, G&G, and BB King bbs to be very good)

If the G&P piston blows out (which they seem to do sometimes), G&G reinforced or a KWA piston seems like a good choice. Check your compression with the parts and if it isn't good, THEN replace them. No point in replacing parts that may work perfectly fine.

Any Pistonheads fit in V7. I have SP130 in my TM M14 and it shoots great. I would not put in a SP150 or stronger inside a V7 box. My first V7 cracked with SP140 and it was the G&P Shell. Go with Sp130 and you are fine with this. I get around 430 fps wit .30 BBs. Well enough for DMR. And if you can, get a stock TM Hop Up unit with TM Bucking and Nub. It still beats the SCS+Systema combo.

Slayer get sorbo too and leave some of it stock. But is TPE better? Would the stock spur gear last in a high fps setting? What barrel would fit since I wanted to use a 550mm?

Heres my list:

G&P M160 motor
Prometheus 500mm M14 barrel
Prometheus air nozzle
2g bucking or systema w/ scs
Guarder sp130
Extreme fire AB long mosfet (which comes with wiring)
Sorbo set
Systema sector and bevel gear (stock spur gear)

Absorbs more impact apparently. I doubt the spur gear would last long at all. All of the G&P gears seem to break. You said money isn't really a factor, so why wouldn't you install the best parts possible? No point in getting a 550mm barrel, just get the M14 length.

Well I have a systema gear set, so should I get a guarder spur gear or a new set. Also, where is TPE sold?

Oh, got ya. Get the Guarder spur gear.
