Does the PWS FSC556 comp/hider effect accuracy? I don't mean POI shift, I mean does it tighten or spread out groups? Thanks.
I had them on two carbines both 16". One in 5.56 and the other in 5.45 and saw no change in accuracy using Russian surplus in the 5.45 or PMC 55gr,
TAP 5.56 75 gr TAP and various 55gr and 75gr handloads in the 5.56. I have pulled both off because they are TOO LOUD. They were tollerable untill the
gun club changed the firing line cover to all metal with no sound absobsion affair. Now they make my head rattle not to mention that one of my shooting
buddies started refusing to shoot next to me.
