gentlemen,
I've been using cans on AR-15s for years and from my own experience I can say that I absolutely notice increased recoil due to the increase in back pressure. An adjustable gas block helped but I feel that even an open muzzle would shoot softer.
I've read they're supposed to act like a muzzle brake but... that puzzles me due to the increase in back pressure. The only way I can imagine a decrease in recoil is if the suppressors' weight is such as to negate the affect of the back pressure.
I can see semiautomatic pistol suppressors at least not adding recoil due to their design of using a piston.
Thoughts?
