These Custom Colt M9 9mm forged lower receivers are a dedicated 9mm design that comes with all the features in the top of the line models in an 80% configuration. These lowers have all the key features you would expect from a high end manufacturer.

NO ROLL PINS!! The roll pin has been replaced with a set screw to eliminate the need of beating on the lower receiver. The rear take down pin detent spring is also held in with a set screw making it easier for you to change buffer tubes. The receiver tension set screw effectively eliminates any unwanted “slop” between upper and lower receivers for superior accuracy.

No FFL required. As determined by the firearms technology branch of the ATF, this lower receiver is not classified as a “firearm” as defined by the GCA of 1968. Operations left to be completed include fire control/trigger group milling, trigger pin, hammer pin, trigger slot, and the safety selector hole.  We have the ability ship to your door because 80% lowers are not considered firearms by the ATF.  

Lead time: Engraving time approx. 7-10 days for all colt 9mm 80% lowers.
