Alpha Silencer from Griffin Armament

In my quest for a small, lightweight .30 caliber silencer that provides as much sound suppression as possible for it’s size we came upon the Alpha from Griffin Armament.

The Alpha comes in at 14.5 ounces with an over all length (OAL) of 7.6″ and outer diameter of 1.5″ and checked all the boxes thus far.  It also has a full auto rating, lifetime warranty and can handle up to 300Win Mag.

Sound suppression is impressive for a package this size and while, for this can, 5.56 wasn’t a primary purpose it is as light as many 5.56 cans and sound suppression comes in at 33db.  In addition to the 5/8×24 minimalist brake it comes with a direct thread 1/2×28 muzzle device and you can pick up a 5.56 end cap if you like.

A special thank you to Silencer Shop for sending this out for testing, it’s going to be sad to see this one go back and even sadder waiting who knows how many months before the tax stamp for mine is approved.

We also continue testing on the AIM AR/M16 H4 .223/5.56/.300 BLACKOUT 9310 MPI Bolt Carrier Group from in this review.
