Description
Rock River Arms has been building ARs in-house for decades, and the RRAGE 2G shows what they can do when the goal is a trim, no-nonsense carbine that still feels like a premium build. The star of the show is the extruded 6061T aluminum A4 upper receiver, which gives you the sharp lines and defined angles you would expect from a billet gun. Pair that with the matching 9.5 inch free-float handguard and the whole top end blends together into one clean, unitized profile. M-LOK slots along the sides and bottom let you bolt on a light or hand stop, or run it slick for a snag-free feel.
What Makes the RRAGE 2G Run
Under the hood, this is a proven LAR-15M setup. The forged lower receiver hosts an RRA single stage trigger and an A2 grip, while the 16 inch chrome moly barrel wears an A2 flash hider on standard 1/2-28 threads, so swapping muzzle devices down the road is simple. The CAR-length gas system with a low profile gas block tucks neatly under the handguard and keeps the carbine cycling smoothly with both 5.56 NATO and .223 Remington loads. The port door is there to keep grit out of the action, and RRA skipped the forward assist to keep the upper lean and clean.
A 5.56 Carbine That Carries Its Weight Well
At 6.7 pounds, the RRAGE 2G handles quickly and points naturally, whether you are working steel at the range, knocking around the farm, or setting it up as a home defense rifle. The RRA six-position tactical CAR stock adjusts to fit different shooters and layers of clothing, and the flat-top upper is ready for whatever red dot or scope you want to run since it ships without sights. One RRA 30-round polymer magazine comes in the box, along with the manual and warranty info. It is a solid, straightforward carbine from a company that machines its own parts and stands behind them.

Frequently Asked Questions
Does the Rock River Arms RRAGE 2G come with sights?
No, the RRAGE 2G ships without iron sights. The flat-top upper and full-length rail across the receiver and handguard give you plenty of room to mount a red dot, low power variable optic, or a set of backup sights. Most owners set it up with an optic right out of the gate.
Can I shoot .223 Remington through the RRAGE 2G?
Yes. The rifle has a 5.56mm NATO chamber, which safely handles both 5.56 NATO and .223 Remington ammunition. That gives you flexibility to run whatever range ammo is easiest to find without any worries.
Can I swap the muzzle device on the RRAGE 2G?
You sure can. The 16 inch chrome moly barrel is threaded 1/2-28, which is the industry standard for 5.56 ARs. The included A2 flash hider works fine as-is, but you can easily swap on a muzzle brake, compensator, or suppressor mount.
Why doesn't the RRAGE 2G upper have a forward assist?
Rock River deliberately built the extruded A4 upper without a forward assist to keep the receiver slim, lightweight, and clean-looking. Most modern sporting rifle users rarely touch the forward assist anyway, and skipping it helps keep the price down without giving up function. The upper still includes an ejection port door to keep debris out of the action.
