ENDEAVOR, Mk4, 5.56mm, 18", Tungsten

There’s a world of options when it comes to AR15s, and for those that want to reach out to further targets or hunt with 5.56, the 18-inch ENDEAVOR® Mk4 chambered in 5.56x45mm is an awesome choice. Despite all the different caliber offerings available today for AR15 pattern rifles, 5.56x45mm still stands as one of the most popular.

Built on our Mk4 – AR15 platform, this ENDEAVOR can make use of just about any AR15 compatible component,  and utilizes a nitride-finished 18-inch 416 stainless steel barrel for enhanced ballistic performance.

Each CMMG® ENDEAVOR rifle is purpose-built for long-range performance, with everything from the Magpul® MOE® rifle stock to the ZEROED™ muzzle brake, and every part in between selected for its utility to the avid marksman.

The EML™ 15 handguard maximizes customization potential. M-LOK® attachment slots at the 12, 3, 6, and 9 o’clock positions give you plenty of real estate to mount accessories, while the Picatinny rail sections allow for easy and solid mounting points for sights and accessories.
