I can't say for a 22. But for my 300blk out, it seems to raise the pressure some. It cycles better with a cyclone suppressor.

I myself would stay away from the bumpfire stocks and 22's. My buddy has one and it takes a delicate touch. Won't cycle well with lead bullets, and seems very picky on what bullets it does like. He paid over 5 bills for it, and I myself felt bad for him.

Funny enough, my son at 5 seems to have the perfect touch for the bumpfire to operate. He let loose a full 30 rounds without a hitch. I only got one magizine full to work, and the owner a few. Lots of jams.
