Product details

Rattlesnake Tactical presents their American-made Milspec RT15, based on a rugged CNC machined lower receiver, and a 15" MLOK rail. This is the perfect way to get into an AR-15 for the first time for new shooters or to begin a new loadout for veteran collectors. Versatility and utility are emphasized in this Mil-spec RT15, providing you with a weapon that can be taken from the box, configured with optics, aftermarket furniture, or slings, swivels, lasers, and lights, for whatever mission that may be at hand! Alternatively, the RT15 can function out of the box with nearly no additional components, using the included Magpul PMAG and your favorite aiming solution.

When designing this weapon, the RTAC team wanted you to hold the RT15 and experience a rifle that is more than the sum of its parts. Picking the weapon up, you will feel the full-length rail to support a variety of shooting styles, positions, and grips. In your hand is the classic AR pistol grip, just in front of the 6-position adjustable stock for the perfect length of pull. When you hold the RT15 into your shoulder, with a hand on the MLOK forend, you are supporting just about 200 individual parts that were made in America, by Americans, with the outstanding quality and workmanship that comes with that. These carefully selected components come together to create the Milspec RT15, a weapon for you, for the competition shooter, for the enthusiast, for the weekend plinker, for the home defender, or tactical professional.

The RTAC Mag Marker band exists to help identify the various calibers that PMAGs can contain these days. This RT-15 is chambered in 5.56, so it comes with the appropriate 5.56 Mag Markers. Your weapon will have a Mag Marker wrapped around the mag well and inside the trigger guard, and you can add the included 5.56 markers to your extra magazines as well. These come in grey and black and fit perfectly around PMAGs or other magazines, and your rifle's magazine well.

To remove or swap the Mag Marker, simply pop open the trigger guard by pushing out the locking pin inside the trigger guard. This will open the guard, allowing the marker to be taken off or swapped for another color or caliber if you are switching upper receivers also. 

Rattlesnake Tactical ships these rifles with:

  • 5 Grey Mag Markers
  • 5 Black Mag Markers
  • 15" cable-lock
  • 1 Magpul PMAG
  • Manual.
