Piston System from Colt Defense

Colt LE6940P RifleColt Defense LLC, one of the world’s leading designers, developers, and manufacturers of rifles and carbines, has advanced its one-piece monolithic upper receiver to introduce the LE6940P. This modular carbine has an articulating link piston (ALP) operating system and offers shooters a highly accurate, lightweight and easy-to-clean AR-platform rifle with an extended lifespan.

“The new LE6940P puts to use a new, improved version of a piston system that Colt originally pioneered for the US Army,” said David Ridley, Vice President of Colt Defense LLC, “Now, any civilian shooter or law enforcement professional has the opportunity to shoot using this superior piston-operated AR.”

The advanced piston carbine (APC) is a lightweight, highly accurate alternative to the traditional direct gas impingement system found in most ARs. The LE6940P utilizes a unique articulating link piston (ALP) operating system, which reduces inherent stress in the piston stroke by allowing for deflection and thermal expansion. As a result, shooters are offered a highly accurate firing experience and the weapon’s lifespan is extended.

Measuring 35 inches with the stock extended and weighing just over six and a half pounds, the LE6940P was designed to be lightweight to reduce shooter fatigue. A one-piece monolithic upper receiver gives ease in assembling parts, disassembling and cleaning. The 5.56mm, magazine-fed carbine has a semi-automatic rate of fire with 700 to 950 rounds per minute. Chambered in .223 Rem (5.56 x 45 NATO), this rifle has an effective range distance of 600 meters.

A continuous rail from the rear of the upper receiver to the front sight translates to unmatched repeatability for mounting optical systems, not found with aftermarket rail systems. In order to enhance the shooters’ versatility in both close quarters and long range, Colt has also incorporated a back up iron sight (BUIS) and a folding front sight.

“The LE6940P exemplifies Colt’s continued dedication to innovation,” said Ridley, “Colt was the first to put a piston system in an AR, and we have continued to improve on that system since, giving shooters an unmatched edge.”
