The ammo is your problem and you have a 1st gen rifle.
CCI quiets will not fully cycle any semi-auto without modification. Really not worth the trouble. CCI standard velocity is fairly quiet out of the 15-22 and will fully cycle the action reliably. With a suppressor the only thing you really hear is the action noise.
