17 HM2 Barrel/ Bolt Handle Conversion Kits for Ruger 10/22
| We are sorry to
announce that our 17 HM2 Conversion Kits have been discon- tinued due to
the lack of availability of good quality ammunition. This article is
presented for educational,
informational, and historical purposes only.
|| Here's How It Works: The 17 Hornady Mach 2 (HM2) is a 17 caliber version of the 22 LR rimfire cartridge. It shoots a heck of a lot faster and flatter, however (click Data at left). The blow-back semi-automatic Ruger 10/22 needs more bolt mass to time its fire, eject, and rechamber cycle to work right with this faster shooting 17 HM2 round... Merely installing a 17 HM2 barrel is not sufficient. Our 17 HM2 Heavy Bolt Handle Assembly adds the necessary mass... a simple, elegant solution. |
Barrel/Bolt Handle Kits: For obvious reasons, we don't sell 17 HM2 barrels without the 17 HM2 Heavy Bolt Handle Assembly... you need BOTH a 17 HM2 barrel AND our 17 HM2 Heavy Bolt Handle Assembly to do a proper conversion of the Ruger 10/22 from 22 LR to 17 HM2 ammo.
Our 17 HM2 Barrels are precision drilled, reamed, rifled, and chambered to match grade tolerances to insure the best accuracy! The .920" diameter barrels are heavy target profile in blue, stainless and stainless fluted. These are fatter barrels than standard 10/22 stocks will fit. We have reasonably priced, adult sized Synthetic Stocks, Laminated Thumbhole Stocks that will fit these barrels. The Factory Contour barrel fits the original Ruger factory stock. We also have Package Deals on Scope Mounts, Action Jobs, and even the brown or gray thumbhole stocks!
