Budget MK18-Style 10.3-inch on a Griffin MK1 Lower with BCM QRF

A budget take on the MK18: an FN barrel cut to 10.3 inches under a BCM QRF rail trimmed to 9.5, on a BCM blem upper and a Griffin MK1 lower. It runs a YHM suppressor gas block and a CAT WB titanium can on a Rearden Atlas mount, with an EOTech 552 on a LaRue riser, an Arisaka light and a Magpul SL-K stock.
