In the middle of a LR-308 build and having problems getting the rifle to lock back on an empty mag and cycle a second round. Using a Superlative Arms adjustable gas block with a Lantac eBCG. Have tried the standard .308 buffer and spring, as well as, a Sprinco Orange spring with heavier 5.3 oz buffer but no luck with any of them. Using a standard mil-spec 7 inch buffer tube. Can get the rifle to lock back on empty mag when charged manually but not when fired. Have changed the bolt catch to an Aero Precison .308 bolt catch but that has also not solved the problem. After firing the first round the bolt group is hanging up just passed the end of the mag so you see the bolt in the extraction area. Any suggestions or advice?
