Ruger 10/22 to HM2 Barrel Conversion Spring Kit

One of four good items needed for a simplest complete conversion from Ruger 10/22 mechanism to HM2

Ruger 10/22 to HM2 Spring part of the conversion kit.

Rimfire Technologies spring kit for conversion of the Ruger 10/22 to 17 HM2 (Mach 2.) Springs and complete directions included in print or by phone.

The only other items needed for a Ruger 10/22 LR to HM2 conversion besides the 10/22 relined barrel are a Moly-Fusion™ kit and the Rimfire Technologies Black Widow Bolt Buffer, designed for the more "impactful" rounds - rather then keeping the steel pin. Because of the Moly-Fusion™ which is not Moly Disulphide, there is no safer way of converting from the very lowly (in price) 22 Long rifle to the hot .17 Hornady Mach 2.

It is recommended you get a barrel pre-broke-in and first-Moly-Fusion™ treatment for you: It will be the most convenient as well as the best out-of-the-box performance. If will provide deluxe accuracy.
