Description
Gemtech went back to the drawing board with the Abyss 5.56, and it shows. This is a hard-use rifle suppressor built around five patent-pending technologies, with the headline feature being a low backpressure design that keeps gas and carbon from blowing back through your rifle and into your face. Anyone who has run a suppressed AR knows that gassy feeling after a few mags. The Abyss cuts that down noticeably, which means a cleaner gun, a more comfortable shooting session, and better reliability from your host rifle.
Built Like a Tank, Carried Like Titanium
The Abyss uses a smart mix of 17-4PH stainless steel and 6AL4V titanium, giving you thicker walls than a lot of competing cans without the weight penalty. The tubeless construction trims unneeded ounces, landing at 16 ounces with a 6.2 inch overall length and 1.64 inch diameter. It wears a high-temp Cerakote finish in black, and it is full-auto rated, so high round count range days and hard duty use are well within its comfort zone. Beyond 5.56 NATO and .223 Rem, it is also rated for 6mm ARC and 5.7x28mm, so one stamp can cover a few different hosts.
Sound and Flash Control on the Abyss 5.56
Gemtech's high-efficiency baffle stack handles the decibel reduction, while the GM-S1 end cap knocks down muzzle flash from the very first shot. That first-round flash is where a lot of suppressors fall short, so it is nice to see it addressed head-on here. Wider 3/4 inch wrench flats make mounting and removal easier when the can gets grimy.
Mounting the Gemtech Abyss
The rear of the can uses the industry-standard 1.375-24 HUB pattern, and it ships with a 1/2×28 direct thread mount installed. That means you can run it straight out of the box on most 5.56 rifles, or swap to just about any HUB-compatible mount you already own. If your safe holds more than one threaded rifle, that kind of flexibility goes a long way.

Frequently Asked Questions
Is the Gemtech Abyss 5.56 full-auto rated?
Yes, the Abyss is fully rated for full-auto fire. Its 17-4PH stainless steel and 6AL4V titanium construction uses thicker walls than many comparable cans, so it holds up to high round counts and sustained rapid fire without babying it.
Can I use my own mounts with the Abyss suppressor?
You can. The Abyss uses the industry-standard 1.375-24 HUB thread pattern at the rear, so it works with a huge range of aftermarket HUB-compatible mounts. It ships with a 1/2×28 direct thread mount installed, so it is ready to go on most 5.56 rifles right out of the box.
Does the Gemtech Abyss reduce gas blowback on AR-15s?
That is one of its biggest selling points. The low backpressure design significantly cuts the gas and carbon that normally gets pushed back through the action and into your face on a suppressed AR. The result is a more comfortable shooting experience, a cleaner rifle, and improved host reliability.
What is the minimum barrel length for the Abyss 5.56?
Gemtech rates the Abyss for barrels as short as 7 inches in 5.56 NATO and 6mm ARC, and down to 3 inches with 5.7x28mm. That makes it a solid choice for short-barreled builds and pistols where a lot of suppressors run into restrictions.
