Product Details

For your next AR-15 build, consider the RTAC mil-spec CNC machined 7075 T6 aluminum complete lower receiver, complete with an American-made lower parts kit, adjustable 6-position stock, and mil-spec buffer tube assembly. This complete lower receiver is standardized and fully compatible with other mil-spec AR-15 components. The receiver is coated with a type 3 hard anodized black finish, and weighs in at 2 pounds. A perfect lower receiver like this forms the strong spine of any modern rifle, be it for duty or law enforcement, match and competition, home defense, or even just plinking and recreational use. Rattlesnake Tactical created this lower as a versatile and adaptable base platform that you can build into a huge variety of weapons once it's in your hands. This freedom to assemble any type of rifle you want comes from the US defense-standard (mil-spec rating), which guarantees interoperability with other AR-15 components. 

As the owner of a new RT-15 complete lower receiver, you can create any type of weapon platform you can imagine. If you wish to build a heavy-hitting monster, you could equip your RTAC lower with a .458 SOCOM upper. Alternatively, you could use a 6.5 Grendel upper for higher precision at long-range, or a 300 Blackout upper for suppressed work. Of course, the most common and practical upper receiver would be a 16" upper chambered in 5.56, as there is not a more traditional choice for an ar-15. This staggering versatility comes standard on RTAC mil-spec lowers. You can create any type of rifle, using any upper receiver you see fit
