Want more barrel rigidity without added weight?

A Hardened Arms 16" socom profile upper delivers the same ballistics as a 16" M4 without the lost rigidity of grenade launch cut in the barrel. Rigidity in a barrel has HUGE effects on harmonics of your rifle barrel. Ever notice that a bull barrel outperforms a pencil barrel shot to shot? The socom is a modified military barrel that is lightened under the handguard like an M4 barrel with a .750" diameter from the gas block all the way forward. We highly recommend a socom barrel of a M4 unless you plan on carrying a grenade launcher? If you are lucky enough to have a grenade launcher barrel harmonics go out the window as your launch canisters of freedom down range at those that oppose you. Built with the same machine gun rated 4150CMV barrel steel and QPQ coating that out performs military interior chrome coating specifications it will last most shooters a lifetime. Chambered in 5.56 NATO with a 1/7 twist these barrels will eat 55gr-80gr ammunition with more projectile rotational stability towards the heavier pills. Steel case 5.56 is fun to plink with but load up some match grade 75 grain ammo and see this upper really shine.

Whats your rifle built for?

If you looking for that edge in accuracy over the shooters that refuse to progress past a M4 this setup is for you. Full length picatinny rails on all four sides means your vertical foregrip, back up iron sights, mounted flashlight and tactical kitchen sink will be right in any position. The handguard is mounted to a large aluminum barrel nut via 8x button head hex screws for secure mounting and easy future maintenance. A 16 inch barreled upper will allow you the ballistic velocity for accurate hits out to 600yds while being light enough to carry all day long.

Worry free operating.
