"Tried over 6 kinds of barrels so far. This is the most accurate and requires the least cleaning.

Worth the money twice over.

"I love Prometheus and Angel Custom barrels! It's a standard to have them in all my guns.

"Very, very consistent barrel.I'm running this on a mostly stock CA M15a4, with a Guarder Clean Bucking and a Systema 120 spring.Accuracy is excellent.

Tight bore barrels ARE NOT and I repeat ARE NOT guaranteed to make you gun shoot with a higher FPS.
In order to do so the barrel will have to be perfect without ANY slight circumference changes within any part of the inner barren!
I personally own this barrel.
I like it, and still do!
It has given my gun up to 180ft accurate range (I own echo1 aug)

BUT OVERALL considering the fact that he is not nationwide yet...this is an EXCELLENT BARREL for sure!!!!

"This barrel is amazing. I put it in my mp5 and saw way better accuracy than the stock barrel. At 200 feet i get around a 3 foot grouping and im shooting 28 rps. I also got more range. This thing will make your gun a ton better and keep heads down in the battlefield. This is the best barrel I have used to date.

"for every one who wants to know: IT FITS KWA KM4 Tactical!!! Installed this in my gun and shoots pretty accurate well way more then it was stock. What is shooting some one if you can not hit them, right!?!?!? Well I recomend this cause i think it will make your game play performance alot better and exciting. Matrix .2G BB's work better than Echo 1, KSC and Mad Bulls with this Barrel. Recomended Buy It, Shoot It, Love It!

"I measured my AUG at 530mm, which might be off since I didnt have a flat-out metric ruler/meterstick, so I went with 12"=~30cm.
Unless I measured wrong, the 550mm barrel is too long, so the 509 is next best.

"yes mike yes it will i got it instead of the systema version because they did have it and this thing is a buet its smaller than the stock but it has better accuracy

"Awesome looking inner barrel. It took a little manpower to get it into my Echo 1 DMR but it made it. The only bad thing is that it will stick out of the end of the barrel. That's the only bad thing. Now I need to purchase a barrel extender to keep it safe and keep the gun looking real verses a paintball gun.
Con is the ad says it fits in the M16A2 but should say extender required.

"tape out the barrel on your gun then go online to a conversion calc and compare to 407mm.
407 mm is 13.0236 inches. for the future us this link

"i just got this and put it on my tm mp5a4 and it rocks!! my grouping is way tighter range is better and the barrel isnt really picky on the ammo it takes. this is an awesome buy.
by Cory E. on 11/21/2008
"i also have an echo 1 g36c and i was wondering if this barrel would be a good choice for my gun. i would rather get this one than a systema or mad bull inner barrel and i want to kno if it would work.

"Amazing barrel, custom parts make it Superior to all other barrels even same length. BEST barrel for M16 etc.
by Matt B. on 09/30/2008
"Well, your inner barrel for your KWA M4 is approx. 10.75 inches. Turn that into Millimeters, you have 273.05 mm. The end of your inner barrel should end somewhere before it reaches the end of your flash hider. Typical flash hider is what...about a couple inches, 2.25..your inner barrel goes half way through that about making it about an 1.25 inch into your flash hider. So here goes the math...that 1.25 inch = around 32 mm. take that off of your inner barrel length of 273.05. So 273.05 - 32 = 251.05 + 110mm (Your King Arms Mock Silencer length) = 361.05mm. Almost the typical inner barrel length of an M4 which is 363. But you want to go less that 361.05 to avoid getting a barrel that is too long and poking out of that suppressor you have. So buy one that is as close as possible to that 361.05 minus maybe 10 or so millimeters. If you really want a Prometheus barrel, go with this 300mm barrel.
72_378&products_id=24384. Otherwise I'd suggest
amp;products_id=24367. It's a 310mm tight bore by Matrix. But before you go on what I suggest...I would first take your gun apart and do all the measurements yourself. I did that when I wanted to get an inner barrel for my A&K SPR MOD 1, and without actually measuring it ,I wouldn't have come close to getting a perfect length barrel for my gun. Hope this helped you out some. Goodluck in your airsoft adventures.
