Pretty neat looking muzzle device for an XM177 build.
Great looks, great price, and actually does reduce the muzzle flash on my 10.5” barrel AR15 Pistol. Add a blade brace, and it looks like an XM177 E2.
Would you recommend this? Yes, I would recommend to a friend

Good price flash hider. Brings a 12.5 barrel to just over 16" to avoid tax stamp. After you pin and weld it, that is.
