You should explain it better then , as some of what you said proves some of the other wrong . The Germans were trying to get the bayonet weight OFF of the barrel to help with accuracy , not POI . The bayo sight was for offhand shooting [ Cav use ] because gun handling DOES move POI . But what would I know , I only test fired 100's of 1000's of rounds through 1000's of military rifles [ with and with out bayos ] , scored 1000's of military rifle target matches at my range for over 25 years , shot national bench rest matches , a top finisher in BR-50 , and I build custom rifles . How would that compare to a guy who shoots a few rounds a year , does not even know what bullets he used and how would you even know if your rifle changed 8 inch POI when you shoot 8 inch groups [ see your Gew-88 target ] .
