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
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!
