Cost and place of purchase.

I bought this gun from Airsoftgi.com for $255 USD. It was $250 but the extra 5 bux got me a battery, charger, and 4000 madbull bb's.

Intro/First Impressions.

The box was well presented and the gun was well packaged. You can tell right off the bat that G&G wants to present this thing as a quality, long lasting piece. The styrofoam packaging has a G&G logo stamped on it.


Picking the gun up, it was a bit lighter than I expected, but the looks and feel were so solid and well finished. Especially the plastic, which is all fiber reinforced.
I haven't felt a more solidly built AEG in my hands since the KWA M4a1. I mean just rock solid. It really puts my Classic army and G&P guns to shame. You could literally train with this thing.

Looks.

Since this gun comes with a full stock, the forward handgrip mimics the realsteel size since it wasn't designed to hold a battery. It has to be the most realistic looking MP5 AEG out on the market.


The magnesium receiver is hard-coated with a very durable black finish. The plastic pieces are very rigid and up to the task of heavy skirmishing.




The butt stock battery cap is VERY secure. It would not come loose during a skirmish unless you threw the thing against a rock. The sling mount is also very realistic as it is actually two pieces like the real one.



The receiver is all magnesium to include the front cocking lever and barrel set. The only plastic parts are the same plastic parts on the real gun and the plastic is very rigid, strong, and real looking.

On top of all of this bad assness, G&G had to go and give this thing a functional bolt catch. And yes, it is all metal as well! Not to mention that you can actually perform the "H&K SLAP" all you want as the cocking knob does not impact against anything, and will not snap off like CA and TM AEG's.

The bolt that goes back is a more gray/steel color to offset it from the black receiver unlike Marui which is black on black and doesn't look real at all.

when you pull back the cocking knob, the bolt retracts and reveals the hop up adjustment.



This is one item I had a gripe about. The hop up adjustment seems very "loose" like it may come out of adjustment if bumped. you can see later that I added a strip of electrical tape to remedy this. The design is still much better than the external lever on Marui's design.

The gun comes with a few hundred PSBB .20g bb's, A metal QD flash suppressor, and a low profile scope mount.

The flash suppressor is a nice touch as it is not painted orange. It mounts to the three lug mount system which is blaze orange but is covered up when using the flash suppressor.



The Low pro scope mount was very nicely designed. An allen key is included for mounting it as well. The four latching claws are actually attached to the mount which makes removing and installing it a snap. If I ever need a low pro mount for my other MP5/G3 guns, this will be the unit I get. So much nicer than the many other designs I have used.

INTERNALS!

I don't usually care about internals since I usually upgrade my guns right off the bat anyway. But some people do care about this. If you are one of those people THIS IS THE GUN FOR YOU!!!!!!

Holy SH*T I didn't think I could be more impressed by this gun. read on...

Take Down

2 PINS! 2 PINS! that is all you need to remove to reveal the hop up , barrel, gearbox!

If there was one thing I just could not stand about Tokyo Marui Mp5's was the takedown process. what a PITA! This thing breaks down in seconds.



here are some parts I that bought to add to the G&G gearbox. NONE OF THESE WERE NEEDED! I used the prometheus barrel and bucking and thats it.(still didn't need them but damn, I didn't want to waste my money=() these parts will have to go on another gun that may actually need them(like a classic army haha)


To get to the motor you have to remove two screws just like any other mp5 / m16/4 style motor grip. However the screws that hold the motor plate on screw into brass fittings! Not the plastic like every other brand! This is the same on the RK series as well! Way to go G&G for going the extra mile!


The selector switch is quite reinforced and has a very positive feel to it thanks to the spring and nipple set up it uses. Very well built piece.


The motor is well made and has some stiff magnets. nothing special about it really. It turns the stock spring with no issues at all.



The piston head!
Very kool vortex type design maximizes o-ring expansion and decompression. It also has ball bearings. The O-ring supplied is a bit thin though, I added a #14 one from home depot for a better seal.


The Piston!
Made of stiff Polycarb and LOOK AT THIS! The 2nd tooth is already removed!


Spring guide
Typical reinforced ball bearing spring guide.


Gears
All metal and has a very sturdy sector gear which has a machined inner gear. Very nice set of gears to get as stock.


Gearbox
covered in a very strong , very slick paint. No need to polish this box as it is already slick as can be.

7mm bearings

Yes bearings. :) These bearings seem to be on par with my prometheus 7mm bearings. MUCH better quality than the CA 7mm bearings I have used. PLUS they are already secured in the gearbox! no need for super glue!


Cylinder head

It's polycarb with a funneled brass nozzle. It also has a very large rubber impact cushion which will extend the life of the ver II gearbox it resides in.


Nozzle
The nozzle resembles Guarder brand nozzles in shape and size. It also has internal o-rings for an awesome airseal.

Tappet plate and spring
Both very nice pieces as well. Tappet is quite beefy and the irregularly pitched spring is also of great quality.


Barrel, hop up, and bucking
The barrel Is great! It is crowned in the same manner as Promethues barrels and it has a 6.035mm inner diameter.

The green bucking included has a great airseal. The locking ring on the hop up holds Very tightly and there is a 4-5mm long brass stabilizing ring . Great setup here all around.

The outer barrel is a solid cast peice of metal very solid



Trigger Switch
It is nickel or silver coated and the solder joints are the best I have seen. Better than KWA even! Look...




Comes with a high capacity magazine that feeds great. I have also tried MAG and STAR brand magazines which feed great also. The STAR mags fit a bit tightly, but then again, they are brand new.

The gun chronoed at 365-370fps originally and now with the prometheus, it crones at 385fps. I will post video results of ROF and FPS chrono results soon.



Accuracy.
Accuracy is great once you get the hop up adjusted. I will post more on this soon.

Any Upgrades you have installed.

I bought a Deep Fire piston, Area 1000 piston head, Area 1000 cylinder head, Prometheus barrel, and Prometheus bucking. I only installed the barrel and the bucking. The accuracy didn't change much from this, only the fps bumped up.

I also rewire the thing with 16AWG wire and a Active braking mosfet.

More performance results soon

PROS
- Awesome externals-
- Metal Body (magnesium)
- Awesome internals
- Tightbore barrel
- only $250

Cons
- hop up adjust seemed loose( at least on mine)
- Full stock only (this may or may not be a con for some people including myself)
- your china clone wielding friends will constantly get owned to the point that they won't want to play with you anymore =( (LOL)
- no trades (so what?)



Conclusion.
For 250 bux how can you go wrong? You get so many amazing parts for the price. Just a quality gun.

Even if you upgraded every part in an Echo -1 mp5 it wouldn't hold a candle to this gun. And to even get it close, you would have to spend a mint.

The quality of the craftsmanship and uniqueness of the design are a testament of G&G's determination to satisfy the customer. I have to give it to them. They really do listen to the customer input and put it to use in their design process.

Update? stay tuned!

Very nice review, I'll make any corrections necessary, and move it. Good job.

Alright, corrections made, you make me want to buy this, but I have not the money right now... sadly.

Damn that was fast. Thanks man

Very nice gun review thar!

Makes me want one too...

Nice review, what do you think the max spring the motor can pull back is?

Great review, just got this gun a few day ago as well,
ASGI crono'd mine at 350 which was a little dissapointing but w/e
Also my hop-up adjustment is solid, even after 3k rounds through it, it hasnt budged.

Just noticed but I couldn't edit my previous post, my gearbox isnt black like yours is, its also the version 3 of the pm5.

If your hop-up is loose, remove the barrel/hop-up assembly and put some loc-tite on the nut that holds the adjustment lever in place.

Really? That sucks

Also, what kind of pins are those (referring to the "2 PINS!")

It sucks but at the same time it doesn't because the fore grip is narrow like the real steel one. It is also rock solid unlike so many other battery grips.

Because there is no reason to space save, the barrel is also fully encased in a magnesium block. Not exposed liek on marui or others. again ROCK SOLID!

If you are good with wiring and stuff, you will be able to fit some nunchuks and lipos in the grip if you really wanted.

The two pins are shown in the initial take down photos. One behind the magwell and one on the stock.

Hm, I think my question was a bit vague.

What type of pins are those in the picture? Do they have a hole for a screw or is it a one piece "push out" pin?

I'm a bit curious because I want to minimize the amount of screws needed to take apart my mp5. I take off my stock so much that I replaced the pin with the foregrip's push out pin. Unfortunately, it does not go through all the way, but it is as effective as the other pin.

They are very snugly fitting push out pins. No screws involved.

I own the G&G GR16 carbine and I have got to agree that the internals are absolutely amazing.
my hopup is very secure and never moves.
I think the best part about G&Gs is the enternals, especially the tight-bore barrle.
the accuracy- awsome!
renforced gearbox, I think the internals are gonna last a long time.
I think I couldn't have bought a better AEG with the money, I don't understand why people buy CA and other brands that cost the same as G&G instead of a G&G.
to think that I almost bought a CA myself! yuck!
good review man!

How has the gun held up thus far? Anything prove to be a nuisence? I have been looking for a "GOOD" review on this gun since it came out, and I must say that yours is easily superior to any others ive read. I have been a marksman for my sqaud for years and I have always perfered mp5's as a secondary... recently someone stole my ICS mp5a4... ... so im looking to replace it. Would you say the gun has fairly good groupings at about 75ish feet?

Also... dumb question... but is the front sight removable? cause I don't think my red dot sight will be able to see over the front sight...

Mine came and chronoed at 335, also had a silver gearbox. Seems odd since they advertise 400 and the gearbox for the reviewer here and someone on youtube where both black.

I just got this gun in the other day I just test fired today and it only fires off in semi-auto. when I switch to full it still only fires semi. I would hate to send it back. do you have any idea what the problem might be?

Awesome review. I'll be planning on getting this gun. I was looking at the Classic Army, but this review made me choose the G&G, plus it's cheaper and for only 5 bucks more u get battery charger and BB's. That's just an awesome deal.

I am saving up for this gun and today when I looked on ASGI they changed the price!
The gun only is still $250 but the Basic package (PM5 A4, 4000 madbull bb's, and 8.4 1700mah battery)
is now $265, a disappointment but still not a really bad deal.

What I recommend buying if you have the cash:
Basic package $265 and 3 bags of Systema 0.2G 3000 bbs. $48
SUBTOTAL: $313

Price is high but you can get the ASGI discount code (300off) which lowers the price to $288 (plus free shipping)
and look at what you’re getting:

13,000 polished high grade bb’s

G&G PM5

8.4 1700mah Lipo battery and charger

TOTAL: $288

OH MY, I want that MP5. Time to get rid my Marui. Those internals look amazing. Did you shortstroke the piston? Also, it looks REALLY dry, did it come like that or did you dry everything off? Great review. Looks like a solid gun.

I just bought another one of these Mp5's. It chronoed at 340 fps according to asgi. I will rechrono tonite to confirm the fps, I will then do typical airseal improvements only and then rechrono and post results.

This one also has an unpainted gearbox. I will confirm that the internals are the same as well.

To the above poster, I tried to clean the internal parts for the photos in this review. I wanted to readers to see the actual part and not alot of grease. The stock lube job was quite acceptable, but it is something I always redo to my specs, along with shimming and airseal.

ok on airsoftgi it says the mp5 is 380 fps but on the package it says the gun is 340 is that a mistake or is there a difference

Its not a mistake, Airsoftgi just has it labeled wrong on their website mine also came shooting at 340

Yeah they must just vary because ASGI chrono'd mine at 380.

Golgo,

Thanks for posting this! How long does it take you to go over a new gun and make all the necessary adjustments (e.g. shimming, air seal, etc.)?

This is something I'd like to learn as it seems that any AEG is susceptible to a number of issues and the only way to counter that is by going through the entire gun.

Anyway, this looks like a great choice for a MP5. I like this better than the RIS version because it seems the foregrip is a tight squeeze for batteries.

What 9.6v battery would work with this?

I go through gearboxes very quickly because I am quite experienced with them. Some1 new at gearboxes may take longer. The amount of time it takes depends on how much skill you have. Don't be afraid to take your time and get to know things and get it right.

I used a 9.6v 2000 mah from battle packs .com it is smaller than an 8.4v large but larger than mini's

To all who get this gun, this is the screw that caused the loose hop up. Simply add some loc-tite and snug it up and your good to go.

Thanks.

Re: screw, I don't see a pic?

sorry, here it is...

Thanks, I figured it out once I took it apart. Applied some BLUE loctite and it's better than new.

Hmm, my G&G mp5 has the same problem. My only issue is that I have no clue how to remove the hop up and barrel unit from the top receiver! Can any of you guide me on how to remove it so I can loctite my screw. Thanks!

If your gun came with instructions, it will show you how to field strip it. Otherwise, look here: http://www.youtube.com/watch?v=8YjJpbPP01U

Great review!
You are a great salesman -- I have gone from the desire to purchase a JG Sig 552 to this. And I think I will stick with this purchase.
I would, however, like to see some accuracy testing. I wonder how much range this is good for; I'm interested in playing CQB (which I assume this would be wonderful for), but I will probably be primarily playing Woodland areas.

Ah yes, I've seen this video before... The above video does show how to remove the frame from the top receiver and gear box, but not the barrel and hop up unit. The included manual does not show hop up unit/barrel removal either. Lots of pretty pictures and packaging though. Can anyone help me out?

Anyone know the rps?

With an 8.4v I would say about 16 rps. I don't know the rps of mine with a 9.6v.

Anyone know of a RIS system that will fit the PM5, Makes me regret not buying the A5, as switching the stock would have been much cheaper and easier. If anyone knows???

Uh... any RIS designed for an MP5 will fit...

Thats a negative, ive tried 2 and both failed. G&G makes their mp5's to more realistic specifications and not to TM specs. Im asking if anyone has seen first hand a RIS besides ordering directly form G&G I suppose one that fits.

Well what part doesn't fit... Nothing a little dremel can't fix!

would you recommend this over the ics line of mp5s?
