P.S., the M1 clip is en bloc, not en banc.
Sorry that’s what I meant to say.
“One is part of the weapon design, the other is an accessory.”
I’ll disagree with you on that. All fill magazines. The situations they are used in does not change that fact.
I have - and even though my M-14 had a clip guide, I never used it because firefights don't give you time to play with loading magazines.
Somewhat uniquely, I have used an SKS in one firefight and did use the stripper clips. Not sure I hit anybody that time.
