What makes this lower different than its counterparts? The answer is simple… the KE Arms KP-15 is a monolithic polymer AR-15 ambidextrous lower receiver made from injection molded, 30% glass-filled nylon. Its unique design incorporates the buffer tube, pistol grip, trigger and a 13-inch (LOP) buttstock into the receiver as integral components. The result is an affordably priced, lightweight lower receiver. The KE Arms KP-15 ambidextrous lower receiver features a lower parts kit including a KE Arms SLT-1 trigger (4.5-pound pull, sear link technology) and ambi selector. The take down and pivot pins have built-in detents, which increases durability by eliminating the spring and detent holes. The lower uses a carbine buffer and spring. The buffer detent (should you choose to use it) is held in place with a 5/64” roll pin. The hammer pin area is wider for durability; standard AR-15 hammer pins can still be used, though the KE Arms longer hammer pin is recommended for customers preferring a flush pin for aesthetic reasons. The safety selector spring and detent have been designed to load from the top, then the selector is slid over them. (Standard selectors can work but removing them can be particularly difficult. KE Arms recommends the use of their designated mil-spec selector or ambi selector to make removal easier. Follow the manufacturer’s assembly guide for further instructions.) Weight: 1.698 lbs. Compatible with all Mil-Spec fire control groups Compatible with cassette style match triggers Flared magwell Available in black and flat dark earth MLOK slots at rear of stock for sling attachment Pre-drilled in front for QD socket inserts Uses a standard bolt catch. Cannot accept the PDQ lever. The PDQ lever is exclusive to the WWSD complete rifle. Do NOT use anything other than standard carbine buffers and round springs or the JP SCSS in the KP-15. WARNING!: This item is legally classified as a receiver. You Must be 21 years old to purchase this item and a resident of the same state your transferring dealer is licensed in. The KE Arms KP-15 is compatible with standard AR-15 uppers in calibers including .223/5.56mm NATO, .300 Blackout, 6.5mm Grendel and 6.8mm SPC. The lower receiver is also compatible with 9mm blowback systems, when used with a minimum buffer weight of 5.4oz (carbine). Failure to use a minimum buffer weight of 5.4oz can damage the lower. CERAKOTE: If you intend to Cerakote your KP-15 the manufacturer recommends the bake should be done at low temperatures (<190 Degrees F) and with an upper in place to prevent warping.
