First Shots: Rock River Arms BT-2 ATR Ambidextrous Tactical Rifle

Rock River Arms (RRA) is introducing the new BT-2 ATR rifle chambered in 5.56 NATO. This is ambidextrous carbine incorporates upgraded components to give both left- and right-hand shooters the best possible. The BT-2 ATR starts with RRA’s new BT-2 upper and lower receivers. Made from 7075-T6 billet aluminum, these precision-machined receivers have the strength and rugged performance needed in a purpose-built defensive carbine.

The Radian Raptor charging handle can be released by pulling either the left or right handle, allowing single-finger or palming action to charge the firearm with either hand. Additionally, texturing along the handles ensures no-slip operation from the strong or support side, even when wearing gloves.

Second, the all-new BT-2 billet lower receiver is machined for ambidextrous bolt catch/release and magazine release systems. With these systems, the shooter can place the bolt catch/release and magazine release button on either the left- or right-hand side of the receiver.

Third, the BT-2 ATR comes with an ambidextrous safety selector switch. With the lever positioned on both sides of the receiver, the shooter can easily switch between “fire” and “safe” from the left- or right-hand shooting position.

Accuracy is enhanced by the inclusion of RRA’s proven two-stage Ultra Match trigger group. Wire EDM cut for precision, this trigger offers a crisp, clean break with a 4.5- to 5-lb. pull weight that minimizes shot disturbance and significantly boosts accuracy potential.

The BT-2 ATR comes with the NSP-2 six-position CAR stock to optimize ergonomics from any shooting position. The NSP-2 also includes ambidextrous QD sling swivel pockets for mounting the sling to the left or right side of the stock for a secure sling wrap around the shooter’s torso.

The ambidextrous functions continue with the new RRA BT2 freefloat handguard. M-LOK compatible, the BT2 handguard is 13 inches long and allows a QD sling swivel mount to be attached to the left or right side.
