Griffin Armament's HUB HRT-5K AM is a compact, hard-use 5.56 suppressor built for people who want to knock down gas blowback without hanging a long can off the muzzle. At just 4.51 inches overall and running an industry-standard 1.375×24 HUB rear interface, it's the kind of can that disappears on a short-barreled rifle while still doing the heavy lifting on sound and flash. The low backpressure baffle stack is the whole point here, and it pays off whether you're running a right or left-handed rifle since less gas coming back at your face means a cleaner, more comfortable experience behind the gun.
This one came out of Griffin's R&D work on the full-size HRT-556 AM, then got shrunk down into the short K format. It's built from Griffin's proprietary Nickel 625X alloy using additive manufacturing, with the printed core laser-welded to a machined rear section for durability and warranty serviceability. That construction gives you excellent heat resistance and strength for high-volume and full-auto use without a big weight penalty, with the can tipping the scales around 11.5 ounces at a 1.5-inch diameter.
Because it's HUB compatible, the rear threads to the 1.375×24 standard, which means you pick the mount that fits how you run your rifle. It works with Griffin's own HUB mount interfaces as well as inserts from other manufacturers, so you're not locked into a single ecosystem. Worth noting up front: this suppressor ships without a muzzle device or HUB mount interface, so you'll want to plan that part of your build separately.
Add in a low backpressure flash hider end cap, minimal point-of-impact shift, full-auto rating with no minimum barrel length restriction on compatible rifle calibers, and Griffin's Perpetual Lifetime Warranty, and you've got a flexible short can that earns its spot on a duty rifle, SBR, or any 5.56 build where size and gas management both matter.
No, this version ships without a muzzle device or HUB mount interface. The rear uses the industry-standard 1.375×24 HUB thread, so you choose the mounting system that fits your rifle. You can run Griffin's own HUB mount interfaces or inserts from other manufacturers.

This is a short K-format suppressor at 4.51 inches overall with a 1.5-inch diameter, weighing about 11.5 ounces. It was adapted from Griffin's full-size HRT-556 AM project and shrunk down for people who want low backpressure in a minimal package. It's a good match for SBRs and duty rifles where you don't want a long can out front.
Yes. The ultra-low backpressure baffle stack benefits both left and right-handed setups by cutting down the gas that comes back toward the shooter. That means a cleaner experience behind the gun regardless of which side you run.
