Pre-ordering reserves your lower from the first production batch instead of waiting on the next run. This initial batch is limited, so once it’s allocated, we move to the next production window. Locking in a pre-order holds your spot in the queue, keeps your pricing locked, and gives you a clear timeline so your Colt ® SMG build is ready to go when these start shipping in early spring.
Description:
The A9X is built for shooters who want Colt® SMG 9mm magazine compatibility in a clean, reliable AR-9 platform. CNC’d right here in Fort Worth, Texas, this stripped lower combines tight tolerances, a flared magwell, and full AR-15 parts compatibility so you can build a 9mm that runs as good as it looks with no milling required. Just choose your FFL at checkout and we’ll ship it straight to them.
Machined for ambidextrous use, the COLT® SMG AR-9 features ambi bolt release compatibility so you can run mirrored controls on both sides of the rifle. Compatible with most AR-9 uppers designed around Colt® or Glock® magazine feed geometry, this lower gives you the freedom to build it your way. A black nitrided steel feed ramp with an integrated magazine stop keeps feeding smooth and consistent, while a steel ejector delivers dependable ejection every time. Pair it with a Colt® AR-9 bolt catch for full last-round bolt hold open.
The flared and curved magwell makes reloads fast and natural, and the threaded bolt catch screw keeps everything locked down tight. Builders will appreciate the clean machining, standard AR-15 parts fitment, and overall feel that makes this lower a solid foundation for any 9mm setup.
Finished in Matte Black Type III anodize, the A9X is ready for whatever you want to build next.
