Griffin Armament Suppressor Buying Guide
Every current Griffin Armament suppressor we carry, from the Recce and Dual-Lok duty cans to the Explorr, Sportsman, Bushwhacker and Checkmate: what each one is for, how Griffin's Taper Mount, Dual-Lok and HUB mounts work, and which muzzle devices fit.
How to Choose a Griffin Armament Suppressor
Griffin Armament was founded in 2005 by combat veteran sniper brothers Austin and Evan Green. The company is veteran owned and builds its suppressors in-house at its headquarters in Watertown, Wisconsin. Griffin sells to both civilian and government buyers, and most of its suppressors are built from 17-4 stainless steel.
Every Griffin suppressor is covered by the Perpetual Lifetime Warranty: for the life of the product, Griffin will repair or replace it at no charge if it becomes damaged or defective for any reason other than loss, theft, misuse, or normal wear and tear. The warranty transfers to the next owner, and you don't need to register the suppressor or keep a receipt. Finish wear isn't covered.
Pick the job first, then the suppressor:
- 5.56 duty rifle on a Taper Mount: the Recce 5 or the shorter Recce 5K.
- 5.56 with low backpressure on a Dual-Lok mount: the Dual-Lok HRT-556, HRT-556 AM or HRT-5K AM. The AM models also come with a HUB mount.
- Light 5.56 or .30 cal on a Dual-Lok mount: the Dual-Lok 5 or Dual-Lok 7.
- 5.56 and 6mm on a HUB mount: the Optimus 6.
- .30 cal duty rifle: the Recce 7 (Taper Mount) or the HUB Dual-Lok 7 AM (HUB).
- Light tubeless can for bolt and gas guns: the Explorr 224 or Explorr 300.
- Direct thread, or pinned and welded: the GP5 or GP7.
- .30 cal hunting rifle: the Sportsman Ultra Light HD 300.
- One can for rifles and a 9mm pistol: the Bushwhacker 36 or Sportsman Ultra Light HD 36.
- Big bore rifles like .45-70 and .450 Bushmaster: the Bushwhacker 46.
- Rimfire: the Checkmate HD, or the Optimus Micro if you also want to run it on 5.56.

17-4 Stainless, Inconel and Nickel 625X
Griffin builds most of its suppressors from 17-4 stainless steel, heat treated to H900. Griffin says its internal testing found 17-4 stainless lasts longer in a suppressor than 718 Inconel.
- 17-4 stainless steel: used in every Griffin suppressor in this guide. The Recce 7, Explorr, GP, Sportsman and Bushwhacker 36 are all 17-4 stainless.
- 718 Inconel: the Recce 5 and Recce 5K add a 718 Inconel blast baffle, the baffle that takes the first blast of gas. Griffin also lists 718 Inconel in the Dual-Lok 5, Dual-Lok 7, Dual-Lok HRT-556 and Optimus 6.
- Nickel 625X (AM models): the HRT-556 AM, HRT-5K AM and HUB Dual-Lok 7 AM are 3D printed from Griffin's own Nickel 625X alloy. Griffin's testing showed about 68% higher yield and tensile strength than 3D printed Inconel 625 at 1,200°F. The printed core is laser welded to a machined rear, so Griffin can service it under warranty.
- Printed 17-4 stainless (Optimus 6): Griffin's first production printed suppressor. The machined rear and mount are laser welded to the printed core.
Tubeless or tube-over: the Dual-Lok 5, Dual-Lok 7, Explorr, GP and Sportsman models are tubeless: the baffles are welded together and form the outside of the suppressor, which saves weight and adds internal volume. The Recce 5 and Recce 7 are fully welded tube-over designs built for sustained fire.
How Griffin Did at the Silencer Summit
The Silencer Summit is a sound test hosted by Thunder Beast Arms and open to any suppressor maker. Every suppressor is shot on the same rifles with the same ammo and measured with the same equipment, so results compare directly. The numbers below are the average dBA on the MIL-STD microphones. Lower is quieter.
At the 2026 Summit, 16 of Griffin's 18 results landed in the quieter half of the suppressors tested on the same rifle or pistol. Highlights:
- PRC 22: 133.2 dBA on a 16 in. 5.56 AR, the lowest of all 87 suppressor setups on that rifle.
- Optimus 6: 134.2 dBA on the same 5.56 AR, 5th lowest of 87.
- Dual-Lok 7 AM: 13th lowest or better on all four rifles: tied for 12th of 87 on 5.56, 13th of 55 on subsonic 300 BLK, 13th of 50 on .308 and tied for 13th of 38 on .300 Win Mag.
- Optimus 9 and Optimus 45: 2nd and 3rd lowest of 17 on the 9mm pistol.
- Checkmate AM: 7th lowest of 21 on the .22 LR pistol.
At the 2024 Summit, the GP7 placed in the top third on a subsonic 300 BLK AR (tied for 19th of 62). You'll find Summit results for each model we carry in its section below. Thunder Beast Arms hosted and scored these tests. See the 2026 results and 2024 results.
Griffin Mount Systems: Taper Mount, Dual-Lok and HUB
Griffin uses three main rifle mount systems, plus direct thread and pistol options. The mount on the suppressor decides which muzzle devices you can use.
| Mount | How it works | Used on | Muzzle devices |
|---|---|---|---|
| Taper Mount (RI) | The suppressor threads onto a tapered muzzle device. The taper centers and locks the can for repeatable point of impact. The Taper Mount-RI (Rapid Index) on current Recce and Explorr models mounts 3 times faster than the original and is backward compatible with earlier Griffin Taper Mount devices. | Recce 5, Recce 5K, Recce 7, Taper Mount Explorr 224 and Explorr 300 | EZ Brake (included), Minimalist Brake, Minimalist Flash Hider, Flash Comp, Flash Suppressor, Muzzle Brake, Hammer Comp |
| Dual-Lok | A precision taper and an ACME thread, plus a spring-tensioned locking collar. The device has 60 grooves and the collar has two locking positions 3 degrees out of phase, for 120 effective locking positions. There are no ratcheting teeth to wear out. | Dual-Lok 5, Dual-Lok 7, Dual-Lok HRT-556, Dual-Lok versions of the HRT-556 AM and HRT-5K AM | Minimalist Brake (included), plus Dual-Lok brakes, flash hiders and compensators |
| HUB (1.375x24) | An industry-standard rear thread. Screw in the mount you want: Griffin's or another brand's HUB mount. | Optimus 6, HUB Dual-Lok 7 AM, HUB versions of the HRT-556 AM and HRT-5K AM, Utility Mount Explorrs, Sportsman Ultra Light HD 300, Sportsman Ultra Light HD 36, Bushwhacker 36, Bushwhacker 46 | Plan-A (Taper Mount devices), Dual-Lok HUB Mount (Dual-Lok devices), A2 Adapter (A2 birdcages), other brands' HUB mounts |
| Direct thread | Threads straight onto the barrel | GP5 (1/2x28), GP7 (5/8x24), Optimus Micro (1/2x28) | None needed |
| EZ-LOK | Griffin's quick-attach rimfire and pistol mount | Checkmate HD, Optimus Micro | EZ-LOK barrel adapter |
Plan-A: put Taper Mount devices on a HUB suppressor
The Plan-A threads into a HUB (1.375x24) suppressor and lets it mount on Griffin Taper Mount muzzle devices. It's machined from 17-4 stainless and weighs 2 oz. Griffin offers a Plan-A Short for shorter Taper Mount devices like the EZ Brake and Minimalist Brake, and a Plan-A Long for longer devices. The Bushwhacker 36 and 46 ship with a Plan-A Short. The Utility Mount Explorrs don't include one.
Dual-Lok HUB Mount and A2 Adapter
The Dual-Lok HUB Mount lets a HUB suppressor, Griffin's or another brand's, lock onto Dual-Lok muzzle devices. The A2 Adapter lets a HUB suppressor fit over an A2-style birdcage and lock down with a collar, so you can mount it on rifles that already have an A2 flash hider.
Pistol mounts
For pistols, the Bushwhacker 36 ships with a booster, and the Sportsman Ultra Light HD 36 can take a booster housing for 9mm tilt-barrel pistols. Griffin's CAM-LOK Piston and CAM-LOK Barrel Adapter let many pistol suppressors twist on and off a pistol without changing pistons. The 3-Lug Barrel Adapter fits HK-pattern 3-lug suppressors and mounts.
Griffin 5.56 Suppressors: Recce, Dual-Lok, HRT, Optimus, Explorr and GP5

Griffin HRT-556 AM

The laser welded tubeless body saves weight and adds internal volume, and the ECO-FLOW baffles cut flash and gas to the shooter.
Griffin Optimus 6
The Optimus 6 is a low backpressure suppressor built for 5.56 and rated for 6mm cartridges. It was Griffin's first production 3D printed suppressor, with a quad-tine Flash-Killer end cap tuned for flash reduction.
Caliber: 5.56, 6mm | Length: 6.02 in. | Weight: 15.2 oz | Diameter: 1.73 in. | Material: Printed 17-4 stainless, 718 Inconel | Mount: HUB (1.375x24) | Full-auto: Yes

Griffin Rimfire Suppressors: Checkmate HD and Optimus Micro
Shop all rimfire suppressors.
Griffin Checkmate HD
The Checkmate HD is built to be easy to clean. Griffin's CARBON-GARD O-rings seal the baffle core, so carbon stays off the surfaces that usually foul. Griffin says the tube and core are still clean after 2,000 rounds.

Griffin Suppressor FAQ
What is the best Griffin Armament suppressor?
It depends on the gun. For a 5.56 duty rifle, the Recce 5 or Dual-Lok HRT-556. For low backpressure on a short barrel, the HRT-5K AM. For .30 cal, the Recce 7 or Dual-Lok 7. For a light hunting can, the Sportsman Ultra Light HD 300 or Explorr 300. For one can across rifles and a pistol, the Bushwhacker 36 or 46. For rimfire, the Checkmate HD.
What is the difference between Griffin's Taper Mount and Dual-Lok?
Both use a taper to center the suppressor. On a Taper Mount, the suppressor threads onto a tapered muzzle device. Dual-Lok adds an ACME thread and a spring-tensioned locking collar with 120 effective locking positions, with no ratcheting teeth to wear out.
What does HUB mean on a Griffin suppressor?
HUB is the 1.375x24 rear thread used by many brands. A HUB suppressor takes a separate mount: Griffin's Plan-A for Taper Mount devices, the Dual-Lok HUB Mount for Dual-Lok devices, the A2 Adapter for A2 birdcages, or another brand's HUB mount.
What is the difference between the Explorr Taper Mount and Utility Mount versions?
The Taper Mount version has the mount built in and ships with an EZ Brake. The Utility Mount version has a HUB rear and doesn't include a mount or muzzle device, so you add a Plan-A or another HUB mount.
Can I pin and weld a Griffin suppressor?
Yes. The GP5 and GP7 come pre-drilled for pinning. The GP5 can be pinned on a 10.5 in. or longer barrel, and the GP7 on a 9.5 in. or longer barrel, to reach a 16 in. overall barrel length.
Which Griffin suppressors are full-auto rated?
Most of them. The Checkmate HD is not. The GP7 is full-auto rated up to .308 Win, and the Sportsman Ultra Light HD 300 is rated for 60 rounds, then needs to cool to ambient temperature.
Which Griffin suppressors work on a 9mm pistol?
The Bushwhacker 36 (booster included), the Sportsman Ultra Light HD 36 (with a booster housing) and the Bushwhacker 46, which is rated for pistols up to .45 ACP.
What is Nickel 625X?
It's Griffin's own 3D printed nickel alloy, used in the HRT-556 AM, HRT-5K AM and HUB Dual-Lok 7 AM. Griffin's testing showed about 68% higher yield and tensile strength than 3D printed Inconel 625 at 1,200°F.
How did Griffin do at the Silencer Summit?
Well. At the 2026 Summit, 16 of Griffin's 18 results were in the quieter half on their test rifle or pistol. The Optimus 6 was 5th lowest of 87 on a 16 in. 5.56 AR, and Griffin's PRC 22 was the lowest on that rifle. Thunder Beast Arms hosts and scores the Summit.
Can I buy a Griffin suppressor you don't carry?
Yes. Through Griffin's Factory-Direct Silencers To Your Door program, you buy the suppressor on Griffin's website, and Capitol Armory handles your fingerprints, eForm 4 and delivery to your door, with zero transfer fees. We offer the same service with 22 other Partner Brands.
What warranty do Griffin suppressors have?
Griffin's Perpetual Lifetime Warranty covers repair or replacement at no charge if the suppressor is damaged or defective for any reason other than loss, theft, misuse, or normal wear and tear. It transfers to the next owner and doesn't require registration or a receipt. Finish wear isn't covered.
