Aim7 AMOS HUB Direct Thread Mount 1/2 x 28 or 5/8 X 24 To 1.375 X 24

Description The ‘Universal’ 1.375×24 HUB Mount This 1.375″-24 HUB Direct Thread Mount will convert HUB-compatible suppressors to a direct thread mounting system. To install, simply remove your existing mount mechanism from your suppressor and thread on our HUB Direct Thread Mount using a 3/4″ open-end wrench. Then simply thread the suppressor onto your barrel. Coating: Black Hard Coat Anodized 1.375″-24 Mounting Threads 9mm Bore Weight: 1.7 oz Available in a variety of thread sizes for various firearms   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.

Because the diameter of the mount (we’ll get to that in a second) is in the sweet spot for internal volume of the suppressor, increased hoop strength, and weight/material balance, other manufacturers took notice and used the opportunity to use the same threads specifications to capitalize on consumers loyalty to mounting systems. Dead Air brought their very popular KeyMo QD system from their Sandman suppressor to 1.375 x 24 mount suppressors and the race to win the universal system battle was on. Griffin Armament was also a front runner in the universal mounting system adoption and now has a compatible DUAL-LOK QD system as well. 1.375 – Diameter of Threads in Inches Looking at the below diagram can be slightly overwhelming. Forget major and minor diameters, the 1.375 or 1 3/8 value represents the diameter of the threaded portion in inches. You don’t need to do any math. 24 – Threads Per Inch If the threaded portion of the mounting system was exactly one inch, there would be 24 threads total. It is a standard right hand twist (righty tighty, lefty loosey for those of you who may be slightly less handy around the house). And the threads on the silencer tube are female and the threads on the mounting system are male. I’d draw you a diagram of something going into something else, but I don’t want to make anyone blush.
