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, we have drop in replacement heavy barrels (.920) that are already professionally CNC threaded 1/2x28 TPI (.400 length of thread) 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. 

The barrels are US Certified STAINLESS STEEL and are 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.

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.  For specifically shooting 60 grain Agila bullets, use our 1:9 twist barrels, available in either stainless or blue in heavy barrel or taper barrel configurations.
