Colt M4 20/10 Round 22LR Magazine Conversion


This is a 20 round factory magazine for the 22LR version of the excellent Colt M4 that has been converted to10 round capacity. The conversion is permanent and the magazine cannot be reverted to 20 round usage. The magazine fits all variations of the Colt carbine. As always, I offer a 100% money back guarantee.
