Description
Up for sale is a Colt LE6940P piston-driven carbine, originally acquired as a law enforcement trade-in. This rifle is in good condition and functions as it should.
As commonly seen with many agency-issued rifles, the original stock and receiver extension were drilled and pinned in a fixed position by the department. I have corrected this by replacing the factory-drilled receiver extension with a Lewis Machine & Tool (LMT) receiver extension and LMT stock, restoring normal stock function.
Features
* Colt LE6940P factory piston rifle
* 5.56 NATO / .223 Remington
* Colt monolithic upper receiver
* Factory folding front sight
* Colt Articulating Link Piston (ALP) operating system
* LMT receiver extension
* LMT stock
About the LE6940P
The LE6940P is one of Colt’s more unique and innovative AR-platform rifles. Introduced around 2012, it combined Colt’s proven monolithic one-piece upper receiver with the company’s proprietary Articulating Link Piston (ALP) system. Unlike conventional short-stroke piston ARs, the ALP design uses an articulated operating rod that helps reduce piston-induced stress and carrier tilt while allowing for thermal expansion. The result is a cleaner-running, durable piston-operated rifle that retains much of the feel and accuracy of a traditional AR platform.
Condition is good with some surface scratches and wear. See pics.
This is a great opportunity to own a rare Colt piston carbine with documented law-enforcement history and upgraded stock.
