Until recently, firearm suppressors that accepted a screw-in mount in the base were threaded with whatever random thread size the manufacturer chose. No real rhyme or reason, just whichever size matched their silencer diameter and whatever pitch they felt like cutting or tapping. The result was that mounts from one company wouldn’t fit silencers from another company.
Over the last three or four years, this has changed. SilencerCo released the Hybrid 46, and between the extremely universal nature of that .46 caliber suppressor and the size of SilencerCo itself, interest and demand grew for adapters and mounts that fit this suppressor followed by demand for other suppressors that fit Hybrid-compatible mounts.
This 1.375×24″ (1-3/8×24″) thread size at the base of the silencer found itself adopted by more and more manufacturers. It then earned the moniker HUB Mount, aka Hybrid Universal Base.
Today, silencers, mounts, and other accessories that are HUB compatible are available from dozens of manufacturers. Whether you’re looking for a 3-Lug mount, a pistol booster, fixed mounts for your rifles, QD systems, etc., you can find it!
Over at Silencer Shop, a simple search nets dozens and dozens of HUB compatible accessories and silencers.
While it certainly isn’t mandatory, if you’re in the market for a new suppressor I’d definitely recommend taking note of the mounting system and likely giving a few extra “buy me” points to any can that works with HUB / 1.375×24 threaded mounts and accessories.
