This is our new 9 mm carbine based on the 30DMG pistol but in a full size frame, similar to our 30SST. The grip is our most ergonomically designed grip system incorporating a solidworks designed profile allowing the use of standard glock style magazines (17 and 33 round only), with a low profile magazine release and decal grip panels. The lower is machined from aircraft grade aluminum, provides cleaner lines and lighter weight than our standard steel receivers. The Handguard is produced from an aluminum extrusion, has no fasteners, and is free floating. The inner diameter of the Handguard is 1.570 inches. The pistol also includes additional upgraded features such as adjustable front and rear sights, plus cerakote tungsten coating.
