    An absolutely exceptional skeletonized BCG for any AR build. Be prepared to tune your gas system and buffer weight to compensate for just how light this thing is. The included NiBx bolt in the titanium nitrided BCG is a great upgraded feature included. I’m running this BCG with a Seekins Precision adjustable gas block, and a 1oz home made buffer, to address a short stroking issue on my AR rifle build (18in barrel, rifle length gas system), with only 6.75oz of reciprocating mass (14.5oz is normal), a 25% reduced power buffer spring and a muzzle brake, this AR now recoils like a .22LR and runs like a sewing machine. An ultra lightweight BCG may not be the best option for every build, but for a low recoil precision rifle, the Trojan Firearms ultra light BCG is one of the best I’ve yet found.
