BCM is awesome too. Good choice.. Most new ar owners bought their rifle from well known brands like bushmaster, stag arms, dpms, rock river arms, delton and if they have a bit of money they will get Colt... But there are a lot of goodif not excellent name brand and quality control out there like BCM, Daniel Defense, LMT, LWRC , knights armament, Spike tactical , Vltor, FN.. etc..
Why there are so many..
