A couple months back I set out to build a compact but accurate precision 5.56 range AR, with an emphasis on 50-200yd group shooting. It's recently complete and bound for its first range session in a few days. It's an evenly balanced 8lb rifle. Here's what I have right now, subject to future changes: Build Specs: STS Arms cerakoted lower PSA/Magpul ACS LBK Hiperfire 'Hipertouch 24' 3lb trigger BCM 16" midlength SS 1:8 barreled upper STS Arms cerakoted M16 BCG Ranier Raptor charging handle Magpul MOE handguard, rear MBUS RRA cantilever scope mount Nikon ProStaff 2-7x32 I could see this thing becoming a money pit, but a fun one. Eventually I may ditch the iron sights altogether and massively upgrade the scope. But for now I'm going to play around with it for a thousand rounds or so and sort out what I want from it.
