I've had a 11.5-5.5 that I bought from Bushmaster in '88, have shot it a lot (day and night),never had so called fireworks display. The 5.5 has been removed for a while, and an A1 cage on front now, soon to be A2 cage,
still no fireworks seen. Fire it without the cage, yes, there is a moderate size flame out front. The noise/atmospheric pressure factor is fun with a short barrel.
Not looking for a urinating contest, just stating an opinion based on the one from Oly that I had.
Muzzle blast and flash were considerable with everything I put through it. Three shooters moved to firing positions further away after complaining about it. Function was poor and to make it work, my gunsmith had to enlarge the gas port. If I had an approved SBR with an 11.5" barrel and an A1 or A2 flash suppressor, or an approved original CAR 15 sound moderator, it might have been fun to shoot and it certainly would have been more concealable (with the 11.5" and a flash suppressor, if that were a consideration.
Flyboy asked if the shorty look flash suppresor will fit on the superlight 16" barrel. I believe that it will, and he will gain a couple of hundred FPS as well as reduced flash and muzzle blast over an 11.5" barrel with the 5.5" suppressor. If his rifle functions now, it should continue to do so with the 16" barrel and a slip on.
Aside from his question, what advantage (other than an inch or so reduced OAL) would there be to anyone in the 11.5" with a 5.5" FS over the 16" with a slip over FS, unless he planned to take off the suppressor and go to an 11.5" SBR?
