"mixed feelings"

Comments and Suggestions: First off let me say that this is a very well made peice and install was a breeze. There is noticable reduction in muzzle climb and somewhat less recoil. It looks mean on the end of the barrel but the real bite is from the muzzle blast. Feels like a small nuke being detonated in front of you. It almost negates the recoil and rise benefits. If you can live with the blast- it does what it claims.

Comments and Suggestions: One of the best on the market for reduced felt recoil and target followup shots.

Comments and Suggestions: This is the most amazing muzzle brake/flash hider I've ever used. It really does both. I ordered one for all my HK-91's and clones. On the HK's I had to clearence the inside shoulder that goes over the knurled part of the barrel by .002" it did not take long and whatever you have to do to use this brake it's worth it.

Comments and Suggestions: Taming the recoil was what I was after. I had already installed the HD buffer, and the difference was very noticeable. Adam suggested this also. Glad to report that the combo of the two has reduced recoil by 50-60%(at least!!!), depending on your ammo. Muzzle flash & sound was diminished greatly, too. Way to go Adam, you were right again!

Comments and Suggestions: I put this compensator on my PTR 91, it tames the recoil more than I ever dreamed. If you have a rifle this will work on, as I said "Buy it now" You will be glad you did.

Comments and Suggestions: I bought this compensator for my HK91 clone. Better than expected. Recoil is significantly less, follow up shots are right there for rapid fire. Very easy to stay on target. I would recommend this comp for any make of rifle.
