works flawless! anyone with an LWRC IC enhanced lower, move it as far forward as you can and add shims

Lower is a LWRC IC 556 with maxim defense brace h2 maxim buffer Upper is LWRC IC 556 10.5 piston the lower shelf is of a different shape & dimensions than standard milspec lowers, ie aero precision, palmetto ect so the trip was hitting way early and causing light primer strikes, was able to get that adjusted with shims now my issue, it might or might not be, I cannot confirm with firing until later this month due to circumstances. anyways, the auto sear and trigger only break once the bolt closes, almost completely, I did get a timing gauge of 0.78~ give or take 2-3. and it the bolt closes on it, after a little wiggle it will close and drop. Slowly closing the charging handle is different on this upper, it does not mind staying a few mils back if you ride it slowly & you can close it without the bolt closing up(only if slow released) ; compared to an older lwrc m6 model it wants to close regardless, no need for forward assist with slow riding. will this be way to 'late', if that is even a thing? it just acts a little differently than i am used to on other upper lower combos
