Has anybody used one of these uppers?How well do there m3 grease gun mag conversions work?The mags are very expensive($65).Is there anybody that sells a mag well block for the ar-15 or someone tat use too.
There also was a company(i think LaFrance?)that sold a .45 acp ar-15 that accepted thompson mags with no change to the mag.I have been told that the only sell to leo now,but iam not sure,does anybody know if they still sell to anybody or is just leo now?
THANKS
KEVIN
