Bighorn Arms



Northland Shooters Supply (NSS) offers Zermatt Arms/Bighorn Arms TL3, SR3, and Origin custom actions. These actions pair with Savage small shank barrels (1-1/16″ x 20 TPI) or our shouldered prefit barrels. They also have a Remington 700 footprint (accepts Remington 700 stocks, chassis, and triggers).

For the SR3 model, NSS is currently stocking the SR3 Short action (REM 700 feed lips and Wyatt's extended mag cut), SR3 medium action (Wyatts Extended mag cut) and the SR3 Long action (REM 700 feed lips and Wyatt's extended mag cut).


This action is machined from pre-hardened 416 stainless steel. The SR3 is a Bighorn Arms variant of the TL3 where the SR3 has feedlips and the TL3 does not. This difference allows for different magazine well options. The SR3 has options for standard Remington 700 (BDL, and AICS mags), Wyatt's Extended, single shot, and single shot extended magazine wells. The SR3 also has a larger ejection port in order to feed rounds from the top.

Features include:

  • Floating bolt head
  • Interchangeable bolt head so you can run multiple calibers in one action
  • Integrated recoil lug
  • Controlled round feed
  • Mechanical ejector
  • Adjustable firing pin protrusion
  • Available in 20 MOA rail only
