Guns, Dogs and Blades QnA

Well I just got done putting together a little carbine for teaching demos. It is an Anderson lower, Mag pul furniture and as light as I could make it. Went to secure (weld pin) flash suppressor and did not have a correct size roll pin! Arghh! My goal was not to go to town today. I am mounting a DPP red dot on it. Gonna look funky because I took the DPP off a 320 and it is coyote brown. Don’t care price was right.
