KE Arms KP-15 Polymer Complete Lower Receiver with

SLT-1 and Ambi Controls

Please read this entire document prior to use.

WARNING! DO NOT Dry Fire your KP-15 without the upper in place. Doing this can damage the receiver wall in front of the hammer.

Warranty:

• The KP-15 has a lifetime warranty for normal use.

• Sling Attachment points wearing out is not grounds for a receiver replacement.

• If the receiver breaks through misuse or neglect, we will replace it ONCE for $65.00.

• Structural modifications including stock shortening and removal of material and dyeing the receiver void the warranty.

• If you intend to register your KP-15 as an NFA weapon test it thoroughly before doing so in a Title 1 Configuration. Once you Form 1 or Form 2 it, you are legally the manufacturer and we cannot service or support it as easily. Should your receiver require warranty replacement we can only replace it with a title I receiver and we are not responsible for tax stamps or NFA fees.

• Cerakoting: If you intend to have your KP-15 Cerakoted we recommend you use We Plead the 2nd as they are experienced in coating polymer receivers and have our authorization. The bake should be done at low temperatures (<190 Degrees F) and with an upper in place to prevent warping.

Features Include:

• Compatibility with most common AR15 uppers and lower parts kits

• Flared magwell to make reloads under stress easier to perform.

• A1 Length 13” Length of Pull (LOP) Buttstock to fit a wide range of shooters

• MLOK Slots at rear of stock for sling attachment points or run a strap through it for simple sling attachment

• Holes at the front of the stock for QD socket inserts for more sling attachment options

Technical Notes

• The KP-15 receiver uses a Carbine buffer and spring. A standard 3oz carbine buffer is included in your unit.

• The front lugs where the upper receiver attaches are intentionally snug. The upper should be pushed down in place from the top between the lugs. The rear take down pin may need to be tapped in and out with a hammer depending on upper fit.

• The Take Down and Pivot Pins have the detents built into them; eliminating the spring and detent holes in the lower increases durability. Pins insert left to right. Spare pins are available from KE Arms.

• The buffer detent is held in place with a 5/64” x 1” Roll Pin

• Your receiver comes with an SLT-1 Sear Link Technology Trigger Installed. The SLT-1 offers a number of benefits including the ability to put the firearm on safe regardless of hammer position.

• The hammer pin area is wider for durability. Your receiver includes a special long hammer pin. Standard AR15 hammer pins can still be used but we offer a longer hammer pin for customers preferring a flush pin for aesthetic reasons.

• Your receiver includes a KP-15 Optimized Ambi 90/45 degree selector set to 45 degree mode. Disassembly of the fire control group should only be done by an experienced gunsmith or certified armorer. Safety selector spring and detent load from the top and then the selector is slid over them. Removing the selector arms reveals the easy disassemble notch half way between safe and fire. The selector can be pushed out in this position after the fire control pins have been removed.

• The KP-15 is compatible with standard AR15 uppers in calibers including .223/5.56mm NATO, .300 Blackout, 6.5mm Grendel, 6.8mm SPC, .350 Legend; make sure you use the appropriate weight carbine buffer for your rifle to eject at 3:00-4:00.

• The KP-15 is 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.

• Big Bores: .458 SOCOM, .450 Bushmaster, .50 Beowulf, .50 BMG: We will never test these calibers enough to guarantee function and durability over time; use at your own risk.
