Rock River Arms Releases the Abidextrous BT-2 Operator ATR Rifle

 

Rock River Arms has released a new AR-15 rifle, the BT-2 Operator ATR. The BT-2 ATR is a fully ambidextrous platform that features a number of upgraded components. Let’s take a look at what it has to offer.

The BT-2 Operator ATR

The BT-2 ATR is chambered in 5.56 NATO, and uses a Rock Rover billet lower and A4 style billet upper.  It has a 16-inch lightweight, chrome lined barrel with a 1:9 twist. I like the lightweight profile and I’m fine with a 1:9 twist, although I think it’s a little unusual these days when we typically see 1:7 or occasionally 1:8 twists as standard.

The barrel has a low profile gas block and is topped off with an A2 style flash hide. The BT-2 uses a Rock River 13-inch lightweight free float rail with M-LOK slots and full Picatinny top. It has an ambidextrous RRA charging handle. They don’t mention the bolt carrier group specs, but based on Rock River’s other products I’m going to guess it’s their standard mil-spec BCG.

The BT-2 ATR lower has an ambidextrous mag release, bolt hold open, and safety. It’s also  fitted with a RRA two-stage Ultra Match Varmint  trigger. For lower furniture it uses a Hogue beavertail pistol grip and a RRA NSP–2 CAR Stock on a 6 position buffer tube.

 

Overall length of the BT-2 ATR is 32.25 inches with the stock retracted, and 35.5 inches with the stock extended. Weight is 6.85 pounds. The Rock Rover Arms BT-2 Operator ATR ships with one 30-round magazine, a 5-slot Picatinny rail, a QD sling mount, and a manual.
