Our Macon Armory 10 mm direct impingement upper receiver group is based on the M-4 style flat top upper reciever. Our barrels are Cerokote coated and hand-crafted with a 1:16 twist and 5/8 x 24 muzzle thread using 4140 Chrome Molybdenum steel, providing both accuracy, durability and versatility. Uppers are built around an Aero Precision upper receiver and include forward assist and ejection port cover. Uppers are intended to be mated with an ANGSTADT Arms large frame Glock magazine lower, or the new Black Creek Precision Large frame lower. for optimal performance
Currently the DI 10mm uppers are being built one at a time as a special order and for this reason will take one to two weeks to ship. Please Contact Rudy to work out the details for your upper receiver group build in this caliber.
It is the customer’s responsibility to be aware of all applicable laws and regulations regarding purchase and ownership of upper receivers with a barrel length of less than 16″.
