Questions & Answers
Does the 308 bcg work for AR10 or only the lr10?

This is a DPMS compatible bcg. It can be used in a LR308 gen 1 DPMS pattern upper receiver. It will not work in an Armalite AR10 pattern upper receiver. If your upper receiver is a LR308 gen 1 type, it should work. I have been using mine for years with no regrets.

Good quality product by Ken, Verified Owner, June 2, 2022
JP Enterprises has a great reputation for quality products. The one issue I have seen people complain about is the looseness of the gas rings. From what I can tell this is normal. The gas ring is a precision piece that is just the right size. It does...
