Prometheus 6.03 EG Tight Bore Inner Barrel for Airsoft AEG by Laylax (Model: Standard / 590mm)

"These are definitely fantastic barrels; they have an impressive polish and are very stable. They are fairly heavy, so if you want your gun to have more weight in the front, here's part of your solution.

But never again will I buy them. The grouping difference between this and a Modify hybrid 6.03mm is not noticeable until you shoot at 250+ feet, and the difference is hardly noticeable. Of course, that doesn't mean that this barrel is bad at all, it just means that the Modify hybrid is completely underrated. If you play field (like me) and want your gun to shoot the best it possibly can, then get this. If you're one of those guys who has three or more guns that you constantly use and want to upgrade their inner barrels without breaking your bank, get Modify hybrid barrel.s

"Installed in VFC HK 416 CQB. Increased length of stock by approx 107mm, WOW what an amazing upgrade for relatively little money. The BB's rocket from the barrel like a lazer beam. Haven't chrono'd but dont expect any gains/losses of FPS but overall range and groupings increased a LOT. Just a heads up to any 416 owners running stock VFC hop up.....also purchased purple Prometheus bucking and the bucking will NOT fit. It's too thick. Confirmed with tech this is not a good matchup (prometheus bucking and VFC hop up.) Keep the stock VFC hop up which is good quality and fits perfect. Couldn't be happier with purchase of barrel. HIGHLY recommended. Best $50ish you can spend.

"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.

"OK LETS START WITH SOMETHING.

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.

"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.
