Had to have a Spare... 12/21/2016
Bought this spare 5.56 bolt JIC the OEM goes down or Murphy pays a visit. Bought when WC had em on sale, couldnt go wrong with people who know quality and having done business with WC for some time now. Headspaced/TEST-fired and stuffed inside my BCM grip. Gtg. Thanks Wilson

one of those you just gotta have 1/7/2014
Picked up 2 of the bolts for spares just incase a gun goes down, Didnt find any MPI marking on either, But if Wilson says they have been tested I have no reason to not believe. Been buying Wilson parts since the early 90s This shop doesnt deal in junk
