KE Arms introduces their new KP-9, a monolithic polymer 9mm AR lower receiver.

Phoenix-based manufacturer KE Arms makes a variety of firearms-related products, from small parts up to complete firearms. Their most recent claim to fame has been the release of their new KP-15 monolithic polymer AR lower. This receiver was intended to be significantly more durable than other manufacturers’ prior attempts at polymer AR receivers, as durability has been a widely-reported issue or concern for some shooters with non-metallic ARs in the past. TFB has covered a broad spectrum of this manufacturer’s offerings over the years, and a selection of some of those past articles is listed for you below.

KE Arms @ TFB:
KE Arms manufactures their KP-9 receivers using polymer molds like this one.

Now the company is adding another version of their monolithic polymer receiver to their catalogue: the KP-9. This pistol caliber receiver is designed to accept 9mm Glock 17 and/or 19 magazines, and maintain compatibility with other brands’ 9mm AR upper receivers. For those of you who love Olive Drab guns, there will be a limited run of 500 OD Green KP-9s made this year especially for the #ODGgang. The full text of the press release announcing this new polymer receiver reads as follows.

Another look at the KP-9's modeling - and yes, it takes Glock mags.

KE Arms is pleased to announce the KP-9 Monolithic Polymer Receiver. The KP-9 combines the features of our highly successful KP-15 Monolithic Polymer Receiver with our billet KE-9 Glock magazine compatible lower to make a lightweight, highly durable, cost effective pistol caliber carbine lower.

The KP-9 accepts Glock 17/19 magazines and comes with an adjustable steel ejector making it compatible with a wide range of blowback 9mm AR15 uppers. The magazine release is ambidextrous as standard for right and left handed shooters.

Tooling is scheduled for completion in Mid-July 2021. Production is estimated to begin in August 2021.

The KP-9 will be available in several configurations

    I don't get the hate for Glock magazines in PCCs. Yes, on a technical level they may not be ideal but in reality they run well and are cheap and plentiful. JP rifles have used them for a long time and those guns see a lot of use.

      @Jeff Hewitt CZ Scorpion magazines are about the same, or even less if you compare the translucent factory CZ 30 round magazines to a factory Glock 33 round magazine.

      So I'd prefer Scorpion magazines for looks, and at today's prices, saving $10 or more per magazine. I've got Glock magazines, but no 33 rounders, so I'd be starting from zero in that respect either way.

    It'd be great if you could drop a 8inch barreled upper on this and not be holding a felony. One senator in the 1930s did this to us.
