I decided to compare a few different barrel lengths today through a chronograph. I chose a Colt 16" CRE, my White oak armament 18" spr build and a ballistic advantage 20" build on a aero precision receiver. On my first round of testing I noticed the bolt release felt odd on the Aero precision rifle.
Turns out the roll pin was completely missing! As it happens I put this one together myself with a cheap lpk. I know the roll pin was there before but I guess it was loose. Anyhow, determined to complete my testing I decided to make use of what I had available. I definitely wouldn't take it into combat like this but it got me through a range session.
It further proves the adaptability of the AR platform. Lol. A picture for your enjoyment...
