Building on the popularity of the Colt LE901-16S is the new M.A.R.C. 901 series, which stands for “Modular AR Carbine.” The heart of the system is a multi-caliber design that allows users to reconfigure the .308 Winchester/7.62mm NATO rifle in minutes to a 5.56mm NATO carbine with the use of an Adapter Block Conversion Kit and a mil-spec Colt upper receiver assembly. The result is a hard-hitting .308 AR that can quickly and easily be turned into a compact 5.56mm NATO carbine ready for any mission and tactical of self-defense need. In addition, the profile of the original upper receiver has been redesigned to offer a smoother shape with fewer sharp edges.

The Colt M.A.R.C. 901 family is made up of four variants. Three are “SE” variants, which feature ambidextrous controls, folding backup iron sights, monolithic upper receiver systems and Vltor collapsible buttstocks. The monolithic handguard not only free-floats the barrel, but it also offers an uninterrupted top strip of rail in the 12 o’clock position for mounting sights and optics for fast targeting at any distance. The user can mount modular strips of rail along the 3, 6 and 9 o’clock positions for other accessories, such as lights, lasers and vertical foregrips. The SE variants include the 16-inch-barreled LE901-16SE, the 18-inch-barreled L901-18SE and the Flat Dark Earth LE901FDE-16SE. The manufacturer suggested retail prices range from $2,181 to $2,281.

The Colt AR901-16S rifle, designed to offer a balance between adaptability and affordability, sports a Bravo B5 buttstock and a free-floating tubular handguard with modular rail sections that can be fitted on 16 different planes. The result is a light and handy .308 carbine that can be configured to meet any mission need. The retail price of the AR901-16S comes in at $1,623.
