What’s old is new with Griffin Armament’s new GATE-LOK HUB Mount Interface 1.375×24.  The A2 birdcage is often what you’ll find on factory AR-15s, and while some suppressors were built to be mounted on the birdcage now there’s a more versatile way. Griffin is now providing a way for existing HUB suppressor owners to use their legacy A2 muzzle devices with this new adapter.

Here’s the product description from Griffin’s product page for the GATE-LOK HUB Mount Interface.

Griffin Armament is proud to now offer the GATE-LOK™ mounting system as a 1.375×24 threaded interface.

The GATE-LOK™ mounting system is one of the fastest on the market and accommodates the A2 NATO compensator as well as Griffin’s GATE-LOK™ series proprietary performance rich muzzle device options.

Additionally the GATE-LOK™ mounting system does not suffer from the wear prone issues of ratcheting systems common to the marketplace. Our mounting system was designed to provide trouble free use.

A2 birdcages often are built to different specs, but Griffin has added information on what devices will fit.  I look forward to seeing more innovative solutions like this come to market as the HUB mount continues to grow in popularity.  The GATE-LOK HUB Mount is currently available via their website with an MSRP of $219.95.
