The Griffin Armament taper mount muzzle devices interface with our taper mounted suppressor (RECCE, PALADIN®, Sportsman, Optimus®)

The Taper Mount Hammer Comp provides 2 sacrificial baffles that reduce recoil and ensure maximum service life of your suppressor. Slotted compensating features provide tuned muzzle stability. CNC machined from a solid bar of heat treated 17-4ph stainless steel, the Taper Mount Hammer Comp is built to last.

This muzzle device is 1.89" length from the countersunk thread shoulder to the front face, and is = length to an A2 flash suppressor with .14" thick crush washer, so it can be used in conjunction with so called "14.7" barrels which are marketed as able to be permed to 16.1" non NFA length using an A2 and crush washer. The actual barrel length 14.835" will bring this device and crush washer mounted A2's to ~16.1" breech face to forward surface of permed barrel assembly. Taper Mount Thread Protector is compatible with this muzzle device for added protection of thread mounts.

Includes shim set.

    Taper Mount Hammer Comp Review

    Published by Jared on 7th Oct 2018

    Purchased the Taper Mount Hammer Comp muzzle device and Thread Protector for my AR 15 build directly from Griffin Armament. Product was shipped within 48 hours, arrived on time and as described. Had a gunsmith pin and weld this compensator on a Faxon Firearms barrel and was pleased with the final fit and finish. After a trip to the range, was satisfied with the level of flash suppression. So far so good...planning to purchase the Optimus suppressor to go on it in the near future.

    Fit and finish are excellent; design does a great job with SBRs' and pistols like the other reviewer pointed out.

    Ok, so you have an sbr/pistol. Taper mounts are key with the optimus silencer. I have the flash comp 556, single break 300blk & 556, double break taper mount I use for 6.5 creedmore. The hammer comp for the 1/2x28 is a godsend. Flat shooting out a 10.5 & 11.5 with low concussion. This is the best taper mount IMO. Buy 2... you never know, and they are not easy to come by (waited a year). Thanks Evan and Austin for great products.
