Thread: Suppressors with internal muzzle brake

The main reduction in recoil is due to the increased mass with the weight of the suppressor added to the rifle. A brake puts in an opposing force to that of the leaving projectile in order to reduce recoil.

I would have said that the plates or internal baffling would have caught the blast as well and in doing so would double up like a brake , like a parachute , and slow or dampen the recoil . Blast pushes the rifle forward when caught in baffles - if you didn't screw it on it would shoot off the end as it catches the blast and is propelled forward. As it is screwed to the barrel it pushes the whole rifle forward to some extent and dampens the recoil effect.
Thats the way I see it anyway.

Exactly. Old mate had a MAE suppressor on his Sako 75 3 hundy WM, the scope kept coming off the receiver dovetail on firing. So much was the recoil reversed, that the recoil setting dovetail on the Sako was ineffective. Ended up machining a notch into the side of the dovetail and a adding a claw and grubscrew to the mount.

It is a closed system. Gases cannot escape the suppressor backwards. Recoil is a product of conservation of momentum. It will have a small effect as you described, because after hitting the baffle the gases move back and hit the previous baffle/rear of suppressor causing in increase in rearward thrust. The suppressor will slow the process a little as well as slowing the gas escape from the front of the suppressor.
