Rather than invest the time and expense to get your factory stainless steel Ruger 10/22 barrel threaded (and hope it gets done right), we have drop in replacement barrels in factory taper configuration that are already professionally CNC threaded 1/2x28 TPI and come WITH the thread protector, at a price that's just about what a one off threading job would cost you.  The barrels are perfect for any 1/2x28 threaded suppressor or accessory that required .400 length of thread. 

The barrels are US Certified STAINLESS STEEL with a polished stainless finish.   The barrels are 1:16" twist, which is perfect for standard or high velocity ammo.    The barrels do not have any iron sights installed and are designed to be used with a receiver mounted scope or similar optics.  Installation is fast and easy with no modifications to your rifle.  Simply remove the stock, unscrew the 2 cap screws that hold the barrel in, remove your factory barrel and install this new one.
