This was my first AR-15 build, chambered in my favorite caliber, .300 AAC Blackout. Sans handguard, monopod, and front bipod, all furniture is MagPul (PRS butt stock, MIAD pistol grip, PLEVEL magazines, AFV 2 fore grip). The Accu-Shot BT13-QK-PRM monopod attaches nicely to the buttstock. Leupold Mark-AR scope functions perfectly. Leapers bipod adds three-leg stability. UTG green laser adds the "cool". Oh yeah, ambidextrous side-charging upper from Grizzly is the icing on the cake!
