Nice addition - FAB Defense AR-15 Survival Buttstock w/Built-in Mag Carrier

Fitment/adjustment is a little tight but with that you have no play or rattle. Attachment fairly easy either by using a pin or small screw driver to hold the slide/adjustment pin down by inserting into the hole on top of the stock or, by pulling down on the rear of the slide adjustment lever. This will retract the adjustment pin far enough to mount on the stock tube. Extra 10 round mini mag fits nicely into the rear of the stock and will accept larger round mags as well. Mounted the FAB Defense MBA Mono-Pod Buttstock which adds about 1.5" to the end of the buttstock but can use slide adjustment to compensate. Over all well worth the mod.
