Tactical Solutions Ruger 10/22 Barrel 16.5" Matte Black Threaded A light weight Ruger 10/22 barrel with chromoly bore and .920 dia aluminum sleeve. This gives heavy barrel stiffness with reduced weight but, it retains a nice balance for aiming and shooting off-hand.. The muzzle features an 11 degree target crown and is threaded for our removable muzzle brake (order separately). A screw-on thread protector covers the threads when you want to shoot or go hunting without the brake installed.
