KE-9 BILLET RECEIVER (Standard and Ambi)

The KE-9 Billet lower receiver is precision machined in-house from hi-grade billet master plate to milspec standards making it compatible with most milspec 9mm uppers. It features a broached mag well and milspec 8625 type III, class 2 hard anodized. It is ready to be assembled with your choice of upper.

The KE-9 accepts Glock OEM and aftermarket Glock style magazines. The magazine catch is included and is machined from aluminum billet and hard coat anodized. The ejector is included and is secured with 2 set screws.

The bolt catch will NOT work for last shot lock back unless you use an upper with a linkage system to interface with the Glock magazine follower.

WARNING: You must use a heavy 5.4oz or more buffer with blowback 9mm uppers to avoid damaging your receiver.

The bolt carrier group you use must be one that is machined to clear through Glock magazine feed lips.

Magazines NOT locking in OR Upper CANNOT Close
1) Loosen the screws that retain the ejector on the left side of the receiver
2) Insert an empty magazine
3) Close the upper onto the lower
4) The Ejector should now be centered between the top of your magazine and the bottom of the bolt carrier group, allowing magazines to lock in, and the upper to close and the bolt carrier to move freely
5) Tighten the screws that retain the ejector

Upper still CANNOT Close or Bolt Carrier will not move
Though we strive for as much cross compatibility as possible, unfortunately there is no industry wide spec for Glock magazine fed 9mm AR15s. Some bolt carrier groups have a track that is too narrow for our ejector or the track is offset vs the ejector location. In these cases the ejector can be fitted to the particular bolt group and will run properly with sufficient clearance. Contact KE Arms at for further guidance/instruction.
