Product details

Rattlesnake Tactical (RTAC) proudly offers the 300 Blackout RT15 rifle, a 100% American-made weapon for shooters who want to use an AR chambered in the extremely versatile and powerful 300 Blackout. The 300 Blackout round is known as 300 BLK by the SAAMI, has significant advantages over traditional 5.56 NATO and .223 Remington ammunition, and was designed for use by American Special Operations soldiers. The RT15 chambered in 300 BLK retains the versatility and capability that those Special Operations forces required, as you can use this weapon to host a suppressor with subsonic ammunition and effortlessly swap to a supersonic magazine for far-off targets. RTAC includes a full-length 15" MLOK rail on this forged flat-top upper to allow for a variety of shooting styles, stances, grips and accessories. The Mil-Spec CNC machined lower is fitted with an adjustable length-of-pull stock, and has been coated with a type III hard black anodized finish. The RT15 is good to go right out of the box, load the included Magpul PMAG up with 300 BLK FMJ and hit the range with your favorite optic or set of iron sights. For shooters who want to take their rifle to the next level, the RT15 can be configured with optics, aftermarket furniture, or slings, swivels, lasers and lights, for whatever mission that may be at hand. 

The RTAC Mag Marker band exists to help identify the various calibers that PMAGs can contain these days. This RT-15 is chambered in 300 Blackout, so it comes with the appropriate 300 BLK Mag Markers. Your weapon will have a Mag Marker wrapped around the magwell and inside the trigger guard, and you can add the included 300 BLK markers to your extra magazines as well. These 300 BLK markers come in black only, and fit perfectly around PMAGs or other magazines, and your rifle's magwell.

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. 

Your new 300 BLK RT15 ships with 10 Black Mag Markers, a 15" Cable Lock, a Magpul PMAG, and a manual. Specifics listed below.
