Product Details

This Ultralight RT-15 features an advanced metal-reinforced polymer upper receiver, paired with RTAC's poly lower and skeletonized pistol grip, as well as a skeletonized angled foregrip (or AFG) for a much lighter and ergonomic build. With an angled foregrip, you get better control and more accurate target transition. The polymer lower on this RT-15 is rugged and light, making it the perfect rifle foundation. A lighter rifle makes handling and aiming easier for any and all shooters regardless of experience level. With a full magazine loaded, optics, lights, and muzzle device, custom AR-15s can become excessively front-heavy. Get ahead of that problem with the ultralight receiver set in this RT-15! Why go and buy a bunch of aftermarket parts when you can buy a brand new already-customized AR-15 with innovative additions already made?

  • Metal-reinforced polymer upper receiver, lightweight and tough
  • Lightweight Skeletonized Grip
  • Lightweight Skeletonized Angled Foregrip
  • Full Bolt Carrier Group and Charging Handle
  • Polymer Lower w/ Oversized Trigger-guard
  • 6-position Collapsible Stock
  • Magpul PMAG
  • Weighs Only 5.7 Lbs!

The 5.7 lb Ultralight RT15 provides a reduction in sight picture sway and an increase in the duration of time that you can maintain sight picture on target, as your shoulders and arms will not fatigue as quickly compared to using other, heavier, 16” barrel AR-15s. This allows more range time, and more precise shots on target before losing that edge. The RT-15 is an easy-to-use and reliable rifle that is fit for the beginner or the advanced AR-15 collector looking for something new.

Out of the box, this rifle can be loaded up and equipped with your favorite irons or optics, and taken to the range. Ships with an included 30-round Magpul PMAG magazine, 15” Cable-lock for storage, and a manual. 

Make sure to add some additional AR-15 magazines to your order, you can never have too many!

Interested in building your own custom AR-15 off of an RTAC Poly Lower? We have those available here!

This polymer lower does not need to have its castle nuts tightened, torqued, or staked, as it is factory torqued with blue Loctite and will not come loose.
