KE Arms KP15 is a monolithic polymer AR15 style receiver made from injection molded 30% glass filled nylon incorporating the buttstock, buffer tube, pistol grip, and trigger guard into the receiver design as integral components. It has compatibility with most common AR15 uppers and lower parts kits, a flared magwell, a 13" A1 pattern length pull (LOP) buttstock with MLOK Slots at rear of stock for sling attachment points or to run a strap through, as well as holes at the front of the stock for QD socket inserts for more sling attachment options. FFL Required. No mag. New.
Please note: The KP-15 receiver uses a Carbine buffer and spring. Do NOT use anything other than standard carbine buffers and round springs or the JP SCSS in the KP-15. It includes the take down and pivot pins which have the detents built into them; eliminating the standard spring and detent holes in the lower.
The buffer detent (should you choose to use it) is held in place with a 5/64” Roll Pin. It is compatible with all Mil-Spec Fire Control Groups, and cassette style match triggers including the KE Arms DMR and SLT units. The hammer pin area is wider for durability, and standard AR15 hammer pins can still be used but longer hammer pins are available from KE Arms if you prefer a flush pin.
Safety selector spring and detent load from the top and then the selector is slid over them. Standard selectors can work but removing them can be particularly difficult. You can obtain an optimized mil-spec selector or optimized ambi selector from KE Arms to make removal easier. The KP-15 is compatible with standard AR15 uppers in calibers including .223/5.56mm NATO, .300 Blackout, 7.62x39mm, 6.5mm Grendel, 6.8mm SPC, .350 Legend; make sure you use the appropriate weight carbine buffer for your rifle to eject casings at 3:00-4:00. It is also compatible with 9mm blowback systems with a 5.4oz carbine buffer minimum. Use heavier buffers as long as your gun can cycle reliably. Failure to use this minimum buffer weight can damage the lower. Not tested for 450 Bushmaster, 458 SOCOM, 50 Beowulf, etc, use at your own risk.
