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!

Designed as a direct substitution for Savage small and large shank barrel nuts.

Barrel modification is NOT required.

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

Manganese phosphate and oil finish

Weight: 3 0unces (86 grams)

Made in the USA
