So, I wanted a budget conscious heavy barrelled AR-15 that I could carry in my Eberlstock backpack. Easy enough, combine one Rock River lower receiver with one DPMS heavy barreled upper, add one Bushnell Elite 3200 10x scope in Warne rings and Bushmaster risers and garnish with a Timney trigger
Bipod was a later add-on, I had to grind away part of the inner baffling on the hand-guard to get the attachment flange to fit. Took about ten minutes with the dremel tool.
She's barrel heavy but shoots well, no recoil to speak of but I'm glad it fits in the backpack as carrying it by hand or by sling would be a pain.
