I'm looking for a used 20" M16A1 or M16 barrel for a 22LR upper build. It must be a 1/12 twist, but does not need to be chrome lined. I prefer a well used barrel in order to keep the price down. It also needs the nut, front sight, and handguard cap. An added bonus if it has been cut and re-threaded/crowned to dissipator length, or is a carbine barrel.
