They've been around since 2016, and I am on a VERY tight budget. I can get an 18" for $260 and a bcg for $100. I heard some bad things about Radical but bought a 458 complete upper and never had any problems, and I know quite a few who own them and no problems, but don't have the $600 for their own Grendel uppers. And again, what is a type 2 chamber?
