I guess I shall go first.


This one is pretty new to my arsenal. It has, all the same, performed spectacularly both in bench testing and in the field.

















It is an Asahi Bushmaster. The max range (confirmed hit) I have measured in the field was approx. 90m with a 3 round burst. Max range on a bench test was about the same, so, as you can see, a very consistent performer. That is why I converted the normal iron sights to a scope mount.


I run it at about 300 fps with a .2 because of the joule creep. Even though it chronos at .9J with a .2, when I chrono with a .4 it chronos at almost 2.5J.


Internally, it is a stock Asahi Bushmaster, with a Magna Barrel. The Magna barrel operates on the same principle as the Sheriff LRB, and allows the bb to ride the top of the bore to get some backspin. However, because there are eight grooves instead of one, the Magna barrel doesn't need an Anti-Rotation assembly.


You might ask, why is this in the build-off if it is stock? Because I have modified it heavily according to booster's guides for the Asahi engine. The engine has been completely re-built, with enlarged air passages for more volume. This got me about a 50 fps increase at minimum operating PSI, and increased the joule creep from adding just under 1J to adding almost 1.6J.

Next up is my trusty sidearm.














This is an MGC G17 Seidler Custom. It was made after Tanio Koba bought MGC, so it comes stock with a twist rifled barrel.


This puppy shoots very nicely. The blowback engine is nice and crisp, and the plastic slide makes for a very fast cyclic rate. I have two barrels that I use commonly, one that came stock, the twist rifled barrel, and a barrel onto which I have installed an IER-hop. The sights are adjustable target sights, which allows me to use this pistol anywhere within 200 feet. The twist rifled barrel has no hop at all, so its max range is quite short, only about 50 feet. It will, however, put two bbs in the same hole at that distance. The IER-hopped barrel ranges out to about 190 feet or so, not quite as accurate, but a double tap will get just about anyone out there. It runs at a smooth 275 fps with a .2, and I run .3s for field use. The hop is not adjustable, by the way, it is perfctly filed/tuned to my .3s. I may be stuck with the bbs that I use, but luckily I really like them, so life is good.

One more entry, this is my target rifle and my backup field rifle.














CA M24 CASV. I can't take credit for the awesome paint job or the CASV mounting (though I did fix a couple of issues with the screws), but I can take credit for a lot of the stuff that is inside. As a more conventional build, I will just list the stuff here.



DBC 6.01x534 mm barrel

PDI hop unit with CMI custom arm



PDI Palsonite HD cylinder set

PDI V-trigger

PDI 380% spring

Laylax Sp120 spring



KA Harris Bipod

Leupold Mk 4 3.5-10x40

CASV rails


Cost: More money than I care to admit.


I run this rifle at about 630 fps for target shooting, and at 330 fps for field stuff. Max range at the bench with the target fps is almost 140m (9/10 shots hit torso target) and max range at field fps is about 95-100m. The ER-hop and LRB were very easy installs on this rifle, and pushed the range by a noticeable amount after installation. With the CMI custom arm as well as the aforementioned mods, I measured an increase in effective range of over 50m. Trigger pull is unfortunately hard, but I can't spring for a Z-trigger yet, I have too many projects in the works.

My precious...














Over a year in the making, the gun started out life as a G&P Sentry and switched over to a King Arms body after compatibility problems with the G&P. It' been an interesting journey, but everything is finally just how I envisioned it. She's accurate, reliable, got range, and has everything you would expect from a PolarStar.

My other PolarStar:












(Last photograph taken by captainbingo)


This PolarStar is only possible because of the awesome work that captainbingo did at Bingo Airsoftworks. As an AEG my XCR gave me nothing but trouble (I went through three of them before I got one that worked), but as an EPAR it is the perfect CQB weapon.

finally cracked. mine as well put in an entry since I have nothing to loose! (please excuse the horrific looking pictures, f I can get better pictures taken in the next few days I'll post those instead. :)


Here we go, my MG36"k" (Still deciding on a name :| )


My MG36k started out as a JG G36. I spent days upon days just trying to decide on what G36 I should be picking up. Should I get the Ares? Or maybe a SRC. JG? Or possibly the CYMA. I didn't know weather I should get the G36c or the G36. There were a lot of questions and a lot of digging that I had to do to find out which would be perfect for me. I'll spare you the details but for the most part I picked the JG G36 for a couple of reasons.

1) I would not have to spend $100+ to buy the "G36" conversion.

2) I was told JG's material quality was improved over the previous years.

3) No Trades! (I'll talk about this one later on ;) )

4) Highly upgrade-able with a low starting price.


So I wen't to Evike and fished out the money to start the long MG36 project that would never end. After I placed my Order with Evike I started planning out what I would be getting next and what all I wanted my MG36 to look like. First thing I knew I wanted was a G36 RAS. I wanted a full size but decided that getting the G36k RAS would be just as useful a little lighter and would be a million times easier to find. So when I ordered that I order a couple other parts for my gun as well (Inner barrel, Scope, Suppressor (too small), and a new Gas block) By now My gun was shaping up to be exactly how I wanted it. I had to do some work to the RAS to get it to fit but it was nothing that took more than an hour. All that was left on my agenda of parts was to get a Rail mounted Bipod, Longer Suppressor and the S-mag. After a couple of months of not having money and not having any of the parts I needed in stock, I did a little modification to my MG36. Most notably is the Bipod on the RAS unit. I promise you, you will never find another out there in the world (one that was done before me obviously) It took some modification to the RAS unit and the Bipod to get it fitted on.


So months go by from my last purchase I find a S-mag in stock, and I'm just $10 shy. My dad gets a big ol paycheck and gave me some Bday money (months late, we are rather poor so I don't ask for any money outside of a few bucks once a month for Arizona's or some little snacks.) So he gave me some odd $125 or so, which allowed me to snatch up the S-mag finally (After missing it 3 times) and my new suppressor. So here are the crappy photo's of my gun.







(Sorry no deployed Bipod pics, but it is fully operational :D )


So what do I have left? Well just a new barrel (Dad broke my old new one.) 2 R-hop mods and Hopefully a new hopup unit to do the "Tracer Hopup" and lastly getting custom MG36 trades engraved into the side of my gun! I've come a long way and spent a lot of money but I absolutely love the gun and can't keep my finger off the trigger! The $600ish were well spent and its a gun I will never get rid of.

Custom KJW 1911A1 Zombie Killer Pistol










JohnJayRambo (on YouTube) did all of the designing for the artwork while Jedi270 (Also, On YouTube) and his partner Donnie Peaeson at the trophy house of Ohio County, KY did the engraving work. John sent in his initial design and they had to change it some to work. It took them 80 hours each to do all the engraving. It was eyballed and placed by hand.

Words of Jedi, "It's beautiful"


-Over 80 hours of laser engraving

-Custom Design

-Completely stock internally

-Ivory Styled Plastic Grips

Here's my contribution, my trusty old CA Steyr AUG A2 Proline. That's what it was once upon a time, the barrel and trigger switches are the only stock internal parts left in it, everything else has been replaced and upgraded, even the GB shell has been replaced. There was nothing wrong with the old shell, I'm still using it in a different gun, I just felt like giving my old buddy a treat. My AUG is far from the prettiest gun on the field, because it's not meant to hang on the wall as decoration, it's meant to be used on the field, it's a workhorse, a role it fills very well. It's the oldest gun in my arsenal, I bought it from a domestic retailer back in 2010, not that old really, but it's the oldest gun I have and the one with the most "mileage". I have rebuilt the internals several times and I doubt I'll stop spending money on it any time soon, as it's become my absolute favorite and can be considered my "signature gun" on the field. My previous builds with this gun have been very unreliable, mostly because of my lacking experience, ironically it's that experience that has made it possible for me to make it a serious assault rifle. It has "battlescars" and scratches and the gun body is generally very fatigued, but in my opinion it gives it more character.


My latest build for this gun has been very reliable with good performance as I now have the experience and knowledge to properly tune it, I have also used parts with much higher quality than in the past. It had a major issue with eating AR latches caused by the way the motor cage is designed. It is mounted at a slight angle and slightly off center in the length direction, placing the pinion gear and AR latch dangerously close together. I solved this by shortening the AR latch slightly and rounding off the inner edge of the pinion gear. The pinion gear seems to hold up well and the AR latch is now working perfectly. My AUG has been my "guinea-pig", whenever I wanted to try out a new experimental mod or just try and push the limits, I've done it with the AUG, because it's so easy to work on.



32rps at 370fps with .20g BB's.

Effective range: Approximately 210 feet with .28g King Arms Platinium BB's. Effective range meaning I can hit an opponent's torso at that range.



Internal parts and mods:



VFC V3 gearbox shell with 8mm hardened steel bushings.

Lonex A2 short type high torque motor.

Lonex enhanced piston (the blue one), swisscheesed with corrected AOE.

CA alu piston head.

Deep Fire stainless cylinder.

ASG Ultimate cylinder head and nozzle. (Lonex rebrand).

Deep Fire ball bearing spring guide.

Deep Fire M120 non-linear spring.

Deep Fire tappet plate.

Lonex 16:1 ratio gears shimmed by the bevel.

Lonex sector clip.

Modify steel cutoff lever.

JG AUG motor cage. (the stock motor cage broke)

Modified G&G pinion gear.

Shortened KA AR latch.



Turnigy 16AWG silicone insulated low resistance wiring.

Deans battery connector

DIY mosfet unit (unconventional airsoft) with a dual 12A polyfuse for shorter trip time.

Stock trigger switches

Hyperion G3 VX 11.1v 35C 1800mah li-po battery.


Barrel assembly:

Stock CA 509mm barrel. It had a Systema 6.04x509mm barrel in it, but it actually has better accuracy with the stock barrel. The barrel has been stabilized as much as possible.

Flat-hop mod with Lonex soft type bucking and a DIY flat nub. The bucking is teflontaped to the barrel for maximum airseal

G&P metal hop-up chamber, with elongated screw holes to spring more snugly against the GB.



KA 35mm red dot sight with a riser mount(unknown brand).

Strike Systems Tactical Light

KA 110rd midcap magazines, I occasionally use CA 330rd hicap magazines if my trigger finger is feeling heavy.



I thought the firewood storage in the basement would be a suitable environment for the photoshoot of my battleworn workhorse:


Dat buttplate, hehe.


It's most severe "battlescar", a major crack in the receiver after it, uhm, fell violently on the ground.


Functionality is the name of the game of my AUG, I removed the entire "bolt" to make it easier to work on, I also didn't like the rattling sound it made.


The tactical light is tiny but is pretty bright.

Custom G&P WOC

-Current State



-After the rail install



-Right after I finished building it




Started out as a G&P WOC Challenge Kit with hardened Aluminum internals and standard WOC externals.

-DD MK18 RIS II ACM Rail System

-Civilian MagPul CTR Stock with "color changing" paint job (Depending on lighting, it could be a dark OD one day or Tan another)

-MagPul MBUS Sights

-MagPul XTM rail covers

-Olight M20S Warrior

-Either a RS Knights Armament foregrip (pictured) or a MagPul AFG1

-Mission Spec Irene Adaptive Sling (OD)

-KZ USA Sling Mount

-"Custom" JB welded the doggie ear that I snapped. Decent hold so far. Gives it "Character"

-Everything else is standard A2 equipment


Getting ready to do a internal over haul at some point once I have the money. :a-grin:

I may look into finding someone's old project and use it as a donor gun for mine. Still debating on where this whole build will go. I mainly buy parts, see if I like the feel of the gun, then sell them if I don't like the look/feel. I'm pretty much stuck with the way it is now since that's what seems to work. Also, I ran out of money...That can put a project to hold quick!


ROF is pretty much stock at like 10-15 (I think) and I believe I installed the 400ish nozzle when I built it (came with a 500ish nozzle too). Can't test numbers as I do not have a chrono in my possession (I really need one).


Also, Here's a video on my FB page of the gun firing just recently. Bolt didn't lock back because of the GHK mag I was running in it.
