AR 15 Bolt Stop roll pins -5 pack
Shown as part 102 Above. Sold in packs of 5 ea.
These roll pins hold AR-15 bolt stops (bolt catch... #103 above) to the lower receiver. I'll admit when building I've buggered these up, and the kit usually only has one of them in it. So I bought extras and offer them up for sale.
These may work on some of the LR-308 variants out there... you practically have to have a PHD in AR-10's to know what parts work with what lower on most of the AR-308 variants... so I won't guarantee anything on LR-308/AR-10's.
