Griffin Armament has released their next generation of rifle suppressors; the DUAL-LOK™ series. The DUAL-LOK PSR 7, is designed to be an ideal suppressor for 308 rifles. This new 30 cal suppressor is engineered to minimize sound, flash, and weight, and is advancing suppressor technology with 6 pending patents.
The DUAL-LOK PSR 7 implements ECO-FLOW™ flow through vented baffle architecture that strikes the ideal equilibrium between signature reduction and reduced blowback. The result is less gas in your face and less sound attenuation at a shooter’s ears. Decreased back pressure also means increased reliability: you can spend more time shooting your rifle instead of tuning it.
The Griffin DUAL-LOK PSR 7 utilizes a tubeless design; technology that Griffin imparted in 2010. This Griffin hallmark drastically reduced weight. The DUAL-LOK PSR 7 weighs in at 15.8oz.; that is incredibly light for a 8.9” .308 silencer constructed from 718 Inconel and 17-4 stainless steel. You can shoot confidently knowing this durable silencer will handle intense firing schedules; it is full auto rated, with no barrel length restrictions, up to 300PRC.
DUAL-LOK suppressors earn their name from Griffin Armament’s innovative mounting system. The DUAL-LOK locking collar engages anti-rotational grooves on the muzzle device with 3 locking splines; your suppressor will remain locked while shooting and you can easily remove it after a day of hard use at the range day or a demanding hunt. The new DUAL-LOK silencers are affixed to the precision taper mount with ACME threads, providing repeatable Point of Impact (POI). Just zero your rifle once and you’re done. Griffin designed the DUAL-LOK without any wear points, this rock solid mount requires no disassembly or maintenance from the end user.
This brilliant 30 cal suppressor is also protected by Griffin’s PERPETUAL lifetime warranty: if your Griffin Armament silencer fails. they will fix or replace it from their HQ in Wisconsin. No warranty cards or legal fine print required, allowing you to shoot suppressed confidently with your new DUAL-LOK PSR 7.

If you have an rifle that is 7.62mm (all the way to 300 Win Mag), you cannot go wrong with the Griffin Armament Dual-Lok PSR 7. The PSR stands for “precision suppressed rifle” and when combined to my Faxon match series .308 barrel, yields that result for me.
The PSR 7 is an OTB (over the barrel) design, and in the images, you can see that the mounting device has ~2.6″ over the rifle barrel (including the threaded portion). The suppressor than securely fits over this mounting device and has several features to ensure a positive precise mount each and every time. Besides the DUAL-LOK locking feature (not a ratchet design, so low wear) there are two tapered surfaces. One immediately after the ACME threads and a second on the tip of the mount device providing solid alignment. I’ve included an image with the testing with a Griffin alignment rod to show that precision (it’s at an angle to focus and show the clearance).
If you are looking for a fantastic suppressor that provides consistent repeatable mounting so that you can adjust your scopes zero for the POI and expect same results, you’ll want the PSR 7.

The Griffin PSR 7 is amazing. Mounting and lock up feels great and secure. Used it twice so far. It is my first shoosher. But I am blown away with it. Have it on an AR10. Making shots at 1000 yards plus. Definitely changes the game for making noise.
