Thanks for the input. Nathan, speaking as just one guys opinion, a drilled gas block from the factory would win a sale for me. I chose the BA barrel over your Gunner for my first build for that reason alone. I'm not a builder, just a newb assembler, and having a properly positioned and drilled gas block is a HUGE benefit. I would chose a factory drilled GB over a secondary vender every time as well. I like everything I read about Faxon barrels, and need to decide on a 20" reasonable? weight barrel, and just found out BA is going to offer a 20" fluted as well. For me alone, they'd win if they drill it as nice as the 16" I bought. It just needs to be drilled, not fully installed, and that's how BA ships them. I'm not opposed to ordering through Aim, but it's not my preference. Either way thanks for the response.
