Product Details

This unique RT15 uses a lightweight poly RTAC lower and an aluminum 5.7x28 upper, creating a light and rugged 5.7 AR platform. This rifle will ship with a 50-round PS90/P90-style 5.7x28 magazine, meaning all you need to do is load it up with ammo, add your optics or irons, and you can hit the range!

  • 16” Barrel, 1:9 twist
  • MLOK Handguard
  • RT15 Polymer Complete Lower Receiver
  • Ships w/ a 50-round P90-style Mag
  • 5.10 Lbs (Not Loaded)
  • 6.10 Lbs (Fully-Loaded)

If you are in the market for a 5.7x28mm rifle, this RT15 is a perfect choice. Using the traditional AR-style lower, the 5.7 rifle ejects the spend casings from the mag well into a neat pile beneath your shooting position. Just add your favorite aiming solution to this RT15, load up the included semi-transparent smoke-colored magazine, and you are ready to get to the range!
