Brownells 6.5 Grendel BCG...????

[drykilned]

I bought and installed a Brownells 6.5 Grendel Type II BCG last year and installed in my BCA Barreled Anderson upper. Had multiple failure to lock into battery causing jams requiring one to mortar the BCG in order to correct the jam. Did that only with mag in place and chambering a round from the mag. Worked fine single loading through chamber by hand. I returned the BCG to Brownells and bought another BCA bcg for almost half the cost of the Brownells. Worked just fine. Have built two 18" SS BCA barreled uppers, both now with Anderson receivers and lowers. one with velocity 3# trigger and one with CMMG premium lower parts kit and trigger. Long story short, BCA bcg works, Brownells did not.
