Dude 300BLK with a cookie cutter comp?
I built a 300BLK upper with a cookie cutter. It's actually a pretty good comp but it is absolutely loud AF, which is one of the reasons I bought it. Mostly I shoot match rifles that do not use a comp so if some tool is doing mag dumps next to me with a comped AR it gets annoying. 300BLK with a cookie cutter tends to make them move down the line. Plus it's just stupid fun.
