Alamo Four Star Unveils Big-Gun Muzzle Brake


Alamo Four Star LLC is out with a new muzzle brake for big guns.

The Lubbock, Texas-based maker of firearm accessories on Wednesday unveiled the so-called Cowl Induction Brake, which it says reduces recoil of large-caliber rifles by more than half.

Mark Deros, the company’s founder and chief executive officer, said he was inspired to create the product for hunters and shooters after the traditional factory brake didn’t adequately control the 18,000 pounds of pressure being released from the muzzle.

“I realized after shooting my .338 Lapua for a while that there had to be a better solution than receiving an ‘ass whipping’ with the factory muzzle brake,” he said, according to an article on

The company said it redesigned the geometry of the brake to create a more efficient gas flow, thereby reducing both the recoil and noise level.

The brake retails for $169 and is initially available in .223/5.56, 6mm, 6.5, 6xc, .308, .300 Winchester Magnum and .338 Lapua. Two finishes are offered, including heat-treated black nitrated and satin.

    Be interested in how much it reduces the noise level of the muzzle blast. Most breaks intensify it for the shooter and anyone nearby.

    Doesn’t look any different than the one I had on a Harbor Safety .50 cal a few years ago. The recoil seemed like about a .410 shotgun in recoil force, but after a magazine full, you had enough already.

    I may get one for my .300 Win mag, competition rifle. A good gunsmith is nearby to thread my .75″ muzzle.

    Are those ports slanted to the rear, thus directing the blast and noise back towards the shooter?

      It isn’t pointed at the shooter but it is directed to the rear at an angle….this is how all muzzle brakes work. The expanding gases are vended to the rear to effectively push the muzzle forward thus countering some of the recoil. This isn’t at all new in design but the manufacture is claiming improved performance over other muzzle brakes.

        No all muzzle brakes do not vent to the the rear, many if not most vent to the sides. Manufactures often claim all sorts of marvelous things for their product. I would be leery of a break that vents rearward.

    Is it just me, or are manufacturers now out of control with muzzle brake pricing?
