Combat Carbine – M4A4


Available on backorder



The M4A4 Combat Carbine is our flagship firearm. It combines some of the best features in a solid, dependable platform while also keeping the price low enough to be reasonable.

The M4A4 differs from our M4A3 by employing primarily ambidextrous controls including:

  • BCM Charging Handle
  • Integrated bolt release above the magazine release
  • Short throw safety (45 or 90)
  • Ambi magazine release available upon request.

The barrel is a 4150 Chrome Moly Vanadium steel barrel by Ballistic Advantage which features their Hanson profile, a nitride finish and a pinned nitride gas block. Muzzle device is an A2 flash hider and gas tube is a nitride stainless mid-length.

Upper is our MK1 which is machined to tighter tolerances and features a dry film lube finish on the interior and a black hardcoat anodized exterior. Upper parts kit is milspec except for the stainless coiled roll pins used for the forward assist and gas tube. Bolt Carrier Group is an AO precision with an HPT/MPI bolt, phosphate finish and grade 8 hardware. Rail system is a 14 inch Midwest Industries M-Lok Combat Rail (Other rails and lengths available). Iron sights are Midwest Industries Flip Up Combat Sights.

Lower is our M4A4 Ambi lower. Lower parts kit is our enhanced LPK, augmented with the Combat Carbine magazine release, safety selector and bolt catch. In addition, the roll pins have been replaced with coiled stainless pins and the detents with our NP3/Nickel Teflon detents. Receiver extension is a 6 position carbine length made from 7075 aluminum with a nitride endplate and castle nut. Spring is made from chrome silicon spring wire and is rated to 750,000+ compressions and the buffer weight is an H1 (3.8 oz). Furniture is a US made SOCOM style stock with storage compartments and integrated QD sling mounts, grip is a Magpul MOE Plus with integrated storage.

The trigger is our JTF Combat Carbine trigger kit. It features a Schmid Tool Nickel Teflon trigger, JP Enterprises Enhanced Reliability spring kit, nitride hammer/trigger pins and is polished for a smooth pull and clean reset. This trigger comes in at about 3 to 4.5 lbs and has the reliability of a milspec trigger but feels like match grade trigger.

In addition to a quality carbine, you also get 3 black Surefeed 30 rnd E2 magazines, a quick adjust 2 point sling, QD swivels and QD mounts for you handguard or rail.

So for under $1300 you get a complete kit including:

  • Complete Carbine
  • Quality iron sights
  • 3 high quality magazines
  • US made 2 point sling

These Carbines are generally made to order and can take up to a month to build, tune, test fire and ship to your FFL. Current lead time on lowers (unless you supply your own or purchase a different one) is 2 months unfortunately.
