Designated the Colt AR15-A4, Lightweight LE Carbine, the AR6720 was designed to meet the needs of the law enforcement officer.

In partnership with Colt, it is available exclusively through Clyde Armory Law Enforcement Supply.

Designed specifically for the Law Enforcement patrol officer, its lighter platform recognizes the need to minimize weight while not compromising durability as firearms are generally carried for long periods of time and weight becomes a significant factor. The AR6720 represents a new generation of Colt rifle, which comes standard with an optics ready rail and a flip-up rear iron sight.

Colt’s use of the MaTech flip-up sight is unique among flip-up rear sights in that it has adjustment for both windage and elevation and its slender design allows for maximum peripheral vision when in use giving the shooter the most unobscured view of the target. These are also the reasons that the MaTech flip up rear sight has been the US Military standard for almost a decade.

The 16” standard weight barrel is magnetic particle tested after proofing by Colt to ensure every barrel is made of perfect steel with zero flaws. Because of this tight quality control, Colt barrels are durable enough to handle thousands of rounds of highly accurate semi-auto fire yet maintain a lightweight profile. Its 1:7 twist gives it the flexibility to use the widest range of ammunition from 40 grain varmint rounds to 77 grain long range match, while maintaining ballistic stability.

The bolt head is also magnetic particle tested by Colt to ensure all steel surrounding the cartridge is perfect and without flaw. These extra steps of quality are what set Colt rifles apart from other AR-15 type clones.

The AR6720 is a hybrid of Colt’s Government Carbine model AR6520 and Colt’s Flagship M4 Carbine model LE6920. This Lightweight Law Enforcement Carbine has a new roll mark of AR-15A4 recognizing Colt’s newest designation of an optics ready carbine.
