Rather than invest the time and expense to get your Stainless Steel factory Ruger 10/22 heavy barrel threaded, and hope it gets done right, this barrel is a drop in replacement heavy barrel (.920) that has already been professionally CNC threaded 1/2x28 TPI (.400 length of thread) and come with the thread protector.. The barrel is perfect for any 1/2x28 threaded suppressor or accessory.
The barrel is 16.5 inches long, made from Stainless Steel and has a polished stainless finish. The barrel is 1:16" twist, which is perfect for standard or high velocity ammo. 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.
Note that the Aguila heavy 60 grain bullet will most likely not stabilize well in this barrel any more than it would in a factory 1:16" twist Ruger 10/22 barrel.
