AR-platform rifles have come a long way, and new piston-driven rifles provide a cleaner, cooler-running alternative to the traditional direct gas impingement system. Luckily, Colt, known for establishing the M4, has also stepped into this corner of the market with its own piston-operated powerhouse, the LE6940P, which author Walt Rauch test-fires in the upcoming Gun Annual 2014.
The Colt LE6940P features a 16.1-inch barrel and a monolithic upper receiver that has a Picatinny rails at the 12, 3 and 9 o’clock positions. The fourth rail, at 6 o’clock, is removable to give access for further cleaning of the rifle if needed. The Rogers Super-Stoc is collapsible to provide a better fit, and the rifle weighs 6.9 pounds unloaded. Its overall length is 35.5 inches with the buttstock fully extended, and 32 inches with the buttstock collapsed. And, according to Rauch, “I also think the ‘P’ for Piston in its model designation could represent “personalize,” as its features enhance its use defensively.”
