Product Details

These rifles may have cosmetic blemishes that do not affect function. This may include forging marks under the finish, scratches, or slight variation in the finish coat.

The RT-15 features an advanced metal-reinforced polymer upper receiver, paired with RTAC's poly lower for a reliable and extremely lightweight rifle. 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 lightweight receiver set in this RT-15!

  • Metal-reinforced polymer upper receiver, lightweight and tough
  • Forward assist, brass deflector, flat-top picatinny rail
  • Lightweight 10” M-LOK handguard
  • 1:8 twist barrel
  • Polymer lower w/ oversized trigger-guard
  • 6-position collapsible stock
  • Magpul PMAG

When you aim and fire your RT-15, the major difference you will notice will be the ease of holding the weapon out and level due to the weight savings. This advantage is critical when taking precision shots from a standing position. The lightweight 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.
