Educational Zone #181 – Product Evaluation – A Rifle Brake for 3gun Nation Competition Guidelines

I got an e-mail from Jeremy from Kahntrol Solutions and he told me that they had designed a couple of new rifle brakes and wondered if I would like to do an evaluation. I said, sure.

He sent me a couple of brakes with these design limitations.

First was a KST3G threaded ½” – 28 (standard AR-15 threads) with a through hole of up to .243. This brake was designed to fit the 3 Gun Nation rules for competition. The MSRP is $94.95.

The other brake was a KST3G-1 threaded 5/8” – 24 (standard AR-10, Blackout, or factory threaded bolt guns such as Remington Tacticals, Savage Tacticals, Ruger Gunsite Scout, Savage Hog Hunters, etc.). It has a through hole for up to .338, and also fits within 3 Gun rules for guys running 7.62 rifles in competition. The MSRP is $94.95.

I had a great AR-15 that Tman and I built back during the Assault Weapon Ban. We had tried to build the rifle as light in weight as possible and had gotten it down to less than 6 pounds. However, since it was built back in those dark days, it had no “flash suppressor” and had simply a blunt barrel.

It has always shot great, but I would prefer to have a muzzle brake on the rifle. Of course, the AR-15 in 5.56 NATO is not exactly a “hard kicker”, but in a light weight rifle, shooting will result in muzzle rise after each shot. Maybe this brake would settle that rise down a little.

Here’s the rifle.

O

As you can see, it has a “pencil” barrel, a Rock River lower, and an Ace stock.

My old buddy Tman wrapped the Ace stock with paracord for me.

O

I had my friend Ray, an excellent gunsmith, install the brake on the rifle for me.

It came out very nice.

O

The brake has six sides, but the top and bottom are flat and interchangeable.

O

We started out the day by shooting at 50 yards with iron sights to check zero. It was shooting slightly high at 50 yards, so I showed my stepson Abel how to adjust the elevation with a rifle cartridge. A couple of clicks and we were right on target.

O

Here I am sighting it in.

O

Of course, this isn’t a “benchrest rifle”, so we stood on our hind legs and shot quick double and triple taps on target.

O

I was very happy to see that “muzzle rise” was almost all gone, and recoil, which had never been “hard”, was now almost completely gone.

This would make putting several shots on target quickly much easier. They just seemed to stack up easily. To be honest, the rifle seems louder to the shooter or to those standing near to him, but that is true of all brakes.

Abel ran the rifle a little and was very impressed.

O

He is right handed, but very left eye dominate and has to shoot left handed.

I gave one of the brakes to my buddy Liem and he installed it on his .308 AR. Here it is.

O

It is a DPMS .308.

It has a Leupold scope with 12 max power.

O

The barrel was already threaded so Liem used the supplied crush washer and installed it himself.

O

It looks nice and clean.

O

Here’s Liem on the rifle. Recoil was just about totally eliminated, but at the cost of some noise. No problem for us as we both wear both ear plugs and ear muffs.

O

And me on the rifle. It shoots very well at 100 yards, even with surplus ammo.

O

If you are interested in eliminating recoil on your rifle and want to keep it “legal” for 3 Gun Matches, give these brakes a look. You can see all models at http://kahntrol.com/.

It’s fun to shoot stuff.
