"As you can see (from my ASR review), the grouping tightened up substantially with the Angel barrel vs. the stock bore barrel. At short range, most of the deviation is from top to bottom, with side to side being quite tight. Grouping size with the Angel TBB was about 2.9”, with the stock barrel being closer to 5”.
Overall, you can see that the performance was greatly increased across the board using the Angel 6.01mm tightbore barrel. I saw an increase in velocity, consistency, usable range, and precision. For the price, this thing gave me one of the best bumps in overall performance that I've seen.
Noticeable increase in range, precision, FPS, and consistency
Great price - $32-$53, depending on length
High quality stainless steel construction
6.01mm inner bore
Must use very high quality ammo with this barrel, however, you should be using good ammo anyways.
Tighter bore barrels require frequent cleaning to prevent jams. (From Evike.com: Matrix, EVIKE, KSC, Marui, WE, G&P, Excel BBs recommended.)
News from Angel Custom: VSR-10 / APS2 / Type96 / SVD / M24 / GBB TB Barrels coming soon.
Angel Custom has produced a few products recently, and if they're half as good as their inner barrel, they are going to be a force to be reckoned with. This thing is extremely well made, and gives you real, measurable performance increases across the board. It is easy to install, inexpensive, and gives you more useable performance for skirmish use. I'm very excited to see what else Angel has in store for the airsoft market!
Many thanks again to Evike, and of course, Airsoft Retreat!
