New 11.3″ Pistol/SBR In 300 HAM’R Introduced by Four Peaks Tactical

The new 11.3” barreled firearm was designed at the request of a law enforcement agency that was looking for a harder-hitting “breacher” caliber but one that retained the light weight and compactness of an AR-15 entry carbine.

The SAAMI approved 300 HAM’R cartridge, designed by the legendary Bill Wilson of Wilson Combat, borrows its DNA from the 300 Blackout concept but is maximized to shoot 30 caliber bullets from 95 to 150 grains at supersonic velocities only…nothing subsonic. A slightly longer case and shorter bullets result in a hard-hitting combo that can launch 130-grain bullets at 2500 fps from an 18” barrel and still fit in standard AR-15 magazines. Four Peaks Tactical is an authorized distributor of Wilson Combat products and is proud to use many of the company’s excellent barrels, receivers and other accessories when building firearms for sporting, home defense or law enforcement purposes.

The new 11.3″ carbine is said to provide excellent terminal performance by delivering over twice the bullet weight of a standard M193 or M855 5.56 cartridge with a muzzle velocity of 2,300 fps. The pistol/SBR will feature a 3.5-pound Rise Armament quick reset trigger, free floated 12″ M-LOK handguard, ambidextrous controls, custom-designed muzzle brake, and a stainless steel 1:13″ twist barrel that can stabilize supersonic 300 HAM’R projectiles. The SBR version of the firearm will ship complete with a Rogers Super Stock for those that wish to complete the paperwork for the NFA version. Customers who wish to purchase the SBR version can contact Four Peaks directly before ordering. Both firearms will be sold for the same price regardless of configuration.
