KE Arms KP-15 Easy Sling Adapter

KE Arms is now offering the Easy Sling Adapter for the KP-15 lower receiver. The Easy Sling Adapter makes use of the rear sling mounting slot on the KP-15.

If you have used this slot before, you know that it can be a bit of a hassle to get the sling tight enough. The adapter is designed so that it is self-tightening as the sling is pulled. It is also much easier to swap slings from the adapter than the fixed slot.


KE Arms KP-9 Monolithic Polymer Receiver

KE Arms is not resting on the success of the KP-15. They are pressing forward with the new KP-9…

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 with a starting MSRP of $159.95

Stripped: Includes all proprietary parts needed

Mil-Spec: Complete with Mil-Spec Fire Control Group and 9mm 5.4oz Heavy Buffer

SLT: Complete with Sear Link Technology Trigger. Sear Link Technology makes these triggers particularly more durable in pistol caliber carbines as there is no traditional disconnector for the hammer to be driven through. This unit also includes an ambi selector.

REKLUSE: Complete with RTS-1 REKLUSE Trigger. The RTS-1 REKLUSE is the next generation Sear Link Technology Trigger with an improved sealed housing and full power hammer spring for increased reliability with combloc primers. This unit also includes an ambi selector.

Limited Run of 500 OD Green KP-9s will be produced in 2021. They will all be sold as this model with the RTS-1 REKLUSE Trigger.


KE Arms KP-15 and Linear Vibration Welding

Those of us who have used CAV-15 lowers and had great results, were excited to see the concept reborn as the KP-15 from KE Arms. As great as the CAV-15 was, it was not without potential weak points including a small number of lowers that split at the weld between the two halves.

This CAV-15 issue is overblown to some extent but not without founding. It has also been projected onto the KP-15 for understandable reasons given the similarity of the concepts. However, it should be pointed it out that the KP-15 is not simply a rework of the original CAV-15 molds. It is an entirely new, ground-up effort – new engineering, new design, and new processes.

KE Arms recently shared a production process photo of a KP-15 lower that shows an example of how the KP-15 was designed with the process of linear vibration welding from the start with input from engineers that specialize in that process. The image shows an alignment tab that ensures that the process works as intended and can then be removed via machining after the process is complete. The result is a weld between the halves of the lower that has shown itself to be stronger than the surrounding material in testing.


KE Arms KP-15 Trap Door Buttplate

KE Arms is now offering a Trap Door Buttplate for the KP-15 lower receiver. It is available as an option for new KP-15 orders or it can be purchased separately for installation by the end-user for current KP-15 owners. Installation is easy with only a little bit of mold flashing to remove and two screws to install.

Once installed, the Trap Door Buttplate allows easy access to the storage area inside the KP-15 stock. The compartment cover can be opened easily without tools thanks to a large recessed tab.


Echo Nine Three Custom Shortened KP-15 Lowers

If you have been following this blog for a while, you’ll know I have a long-time love affair with CAV-15 lowers. One of my lowers was worked over by Echo Nine Three with a number of modifications, the most prominent of which is the shortening of the buttstock. Now that the KE Arms KP-15 lowers are out in the wild, it is becoming clear that these are a vast improvement over their distant relative the CAV-15 and Echo Nine Three is, once again, offering customizations.

The KP-15, like the CAV-15 before it, has an integral A1 length stock but the actual internal bore for the buffer tube is made to accept carbine buffers and springs. This means that there are potentially a few inches of stock that can be removed if the user desires something shorter. Echo Nine Three removes this excess length and fits a new rubber butt pad that is shaped to fit the KP-15 stock contours.

Echo Nine Three is the only gunsmith that is authorized by KE Arms to shorten the buttstock in this way. If Echo Nine Three performs the mod, your KP-15 warranty will still be intact.
