Using the Barloc

Please Read Before Ordering:

  • Some customers have reported a Point of Impact shift if the barrel is struck with a Barloc installed.  

  • American Rifle Company has not fully tested what level of impact is required to cause a shift.  

  • There are no safety issues.  If this may be a problem for the intended use of your rifle, consider using a standard barrel nut or standard shouldered barrel and an action wrench to remove the barrel. 

Product Overview

Product Information:
  • American Rifle Company’s Barloc is a device that enables one to remove and re-install a barrel using only a 5/32″ hex key and a head space gage.

  • It is superior to competing products because it actually preloads the barrel thread promoting long term receiver-barrel joint stability.

  • 90 lbf-in (10 Nm) of torque applied to the 10-32 clamping screw results in a barrel thread pre-load requiring approximately 100 lbf-ft (136 Nm) of torque to loosen!

  • Barloc Nut thread sizes currently available: (Barloc includes Nut Wrench)

    • 1-1/16" x 16 TPI (Remington)

    • 1-1/16" x 18 TPI

    • 1-1/16" x 20 TPI (Mausingfield, Nucleus, Savage small shank)

    • 1-1/8"   x 20 TPI (Savage large shank)

  • Barrel:

    • Shouldered barrel version: Designed for use with barrels having shoulders and shank diameter of 1.250 inches.

    • Threaded barrel version: Four thread sizes are currently available including those for Savage and Rem-age pre-fit barrels.

  • Intended for use with either recoil lugged or lug-less actions.

  • Made from hardened steel
