KAK Industry Compensator - 1/2x28

Installed these on all of my previously equipped A1/2 FH rifles to go featureless. I used the old crush washer and they timed properly with no issues, bayonet mounted fine for those wondering.

I've only shot it out of my 20" so it's hard to rate it's effectiveness as the recoil was already negligible. It definitely wasn't loud like some brakes out there though so if there is some dampening don't expect it on the level of the more aggressive ones out there.

One downside is while the external finish seems fine I'm getting a little bit of green popping up in the tiny holes. It's not a big deal to me but ymmv. As it stands, I'm very happy with this as a low cost featureless option thats not going to blow your (or those around you) eardrums out, looks good, and has the same overall dimensions as the original flash hider.

Great value comp...but has shortcomings. This item is a great value and does provide flash comp but it does toooo much compensation. Has a lot of back pressure to the shooter and out the side, it literally pushes the gun Down. While that can be good it’s something to get used too. One of the strangest muzzle devices I’ve tested. Worth a try for the money, but dollar for dollar I’d stick with a standard bird cage.

I didn't get too much blast from this, so that is a positive, but it absolutely does push the muzzle down, and rather sharply too. For me it is harder to keep on target than using a plain old A2, so not much good to me. Probably is a great value for someone who cannot have an evil flash hider on the gun though, I am sure you could learn to shoot it reasonably well with practice.

Excellent price and option to stay in compliance in CA.

Was worried about overcompensation. Shooting benchrest off bags or bipod, was not a problem. At 100 yards and a high power scope, was able to keep sight picture for next shot.

Not obnoxiously loud like the big holes out the side muzzle brakes.

i had the same issue as another post/customer i saw.The holes in the comp were partially blocked with metal grit of some kind.Im almost sure it was from the drilling of the holes in the comp but one never knows.When i finally install it on my rifle ill be back to complain or praise this comp!?!LOL if it wasnt for the grit i had to clean out i would have given u guys that 5th star....

Got it because it was the cheapest option, swapped it for an a2, on a 16" barrel for me it was extremely loud which is why I changed it, it's also a bit heavy but external dimensions are basically the same as the a2, also made one heck of a flash which was pretty cool but I wouldn't consider that a good thing, just looks awesome when plinking.

It was on sale for $4.99 when I bought it, and it way outperformed my expectations. The ONLY recoil impulse is the bolt returning to battery. If you'd like to get an idea of the recoil, lock your bolt to the rear shoulder your weapon, then hit the bolt release.

It also has a badass Fireball out the top, so if you're using NVG's or are shooting in low light/no light will affect your eye adjustment.

Got a couple of these when they were on sale. This compensator works great. No complaints at all.

Timing it at 12 o’ clock will overcompensates my 10.5” AR pistol. Somewhat lessened by timing it at 1 1 30 or 2 o’clock. Not as much concussion as a brake which is good. Aesthetically looks ok but the phosphate finish on mine was not perfect.

Got this for a dedicated 22LR build solely based on cost. Didn't end up using it because the CMMG barrel was SO heavy just on its own. Haven't found another build to put it on yet so I can't speak on its abilities. It looks goofy, and looked goofy on the barrel. Super easy to time with the 9 sets of holes. One star off because of the weight of the device.
