Product Description

Cobalt Kinetics PRO Muzzle Brake Details

Superior handling and a true competitive advantage are now available in a single AR15 accessory. You can maximize control, recovery, and speed with the Cobalt Kinetics Pro Muzzle Brake!

Our Pro Muzzle Brake is designed for use with any rifle chambered in .223/5.56 caliber with 1/2×28 muzzle threads.  The brake is treated with an all new ultra-performance Black Lithium-iron surface conversion (or LiFe). LiFe treatment increases the steel’s hardness, strength, and resistance to erosion.  At 3.4” long and less than 1″ across, the Pro Muzzle Brake is legal for multi-gun competition.

Superior Engineering

The patent-pending design features a symmetrical linear array of intersecting spheroid baffles that dramatically improve performance. Exhaust energy is vented only to the sides to eliminate dust signature.  The symmetrical port and baffle design eliminate the compromising effects that biased or directional porting can have on accuracy. This unique internal structure of the brake is calculated to produce a dramatic improvement in the brake’s effect.

The extra length and tight bore (.240 thousands of an inch) increase positive energy scavenging. The Pro brake’s action is better described as a “burn” rather than a “burst”. Effectively, the brake is working for more time; thus, improving efficiency. The gain in effect negates the need for biased or directional porting.

Competitive Advantage

The Pro Brake has been carried to victory in numerous competitions by the Cobalt Kinetics Shooting Team (Keith Garcia, Kalani Laker, and Rick Birdsall).  The Pro Muzzle Brake was also used by Max Leograndis to take top honors at the 2017 California Bay Area Rifle Challenge.  According to the team, the Pro Muzzle brake’s outstanding performance was a contributing factor to their success and numerous wins from 2015-2017. The Pro Muzzle Brake is the most effective accessory available for improving the handling and performance of your AR-15.

The Pro Muzzle Brake is a standard kit on all Cobalt Kinetics Team rifle models.

*The Pro Muzzle Brake can be coupled with our Pro Buffer System to further improve weapon control and handling.

The Cobalt Truth

I handled one of these at Firearms Unlimited in Exeter, RI. I have handled and fired a lot of AR’s in my lifetime but the fit and finish on this one is I have to say is the absolute best. I dare you guys or anyone to make a better one.

Thomas Neves
Picked up my first cobalt AR this week. As far as an AR rifle, this I will say is the best elaborate weapons system I have run across as of today…the machine work and design with dual operation components are outstanding. The only thing that would make my rifle any better would be if it was in Tennessee orange and white lol.

Danny Hall
No other AR comes this close to perfection on the market today. Fit, finish, function far surpass anything else, and dual drop means always having the drop in any tactical situation.
