I have a new M&P15-22p and noticed in the manual that I'm not supposed to fire CCI "Stinger" rounds. However, can the CCI "Quik Shok" (which is comparable in grain and fps) be used? I love this li'l piece and don't want to do something stupid. Thanks.

I have one, ser.# DUL****and the manual says it's okay.

In the rifle Performance Center model, Stingers aren't to be used because of a tighter chamber and Stingers are too long.

S&W also doesn't recommend Remington Golden Bullet, Remington Target 22, or Winchester Wildcat. Any and all sub-sonic rounds but both my rifle and pistol shoot match ammo just fine. I suppose the gun may not function reliably with match ammo but that is not the case with mine.

Hope this helps.

Thank you very much.
