Rock River Arms BT91700V1 LAR-BT9G R9 Competition 9mm Luger 16″ Stainless, Black, RRA NSP-2 Stock & Hogue Grip

The Rock River Arms BT91700V1 LAR-BT9G R9 Competition 9mm Luger 16″ Stainless, Black, RRA NSP-2 Stock & Hogue Grip is a purpose-built competition rifle for shooters who want fast, accurate 9mm performance in an AR platform. With a 16″ fluted stainless barrel, lightweight M-Lok free-float handguard, and the proven RRA NSP-2 stock paired with a Hogue grip, this rifle is ready for action at the range or in a match. Per Rock River Arms specs, the R9 Competition delivers sub-MOA accuracy with quality factory ammunition, making it a reliable choice for family shooters and competitors alike.

Key Features

• 16″ Fluted Stainless Barrel — Why it matters: The fluting reduces weight and improves heat dissipation, so you can shoot longer strings without accuracy drop-off. Per Rock River Arms, the 1:10 twist rate stabilizes a wide range of 9mm bullet weights.
• 15″ Lightweight M-Lok Free-Float Handguard — Why it matters: This slim, ventilated handguard gives you plenty of rail space for lights, lasers, or a bipod, while keeping the rifle balanced and easy to handle for shooters of all sizes.
• RRA NSP-2 CAR Stock — Why it matters: The NSP-2 (Non-Slip Pad) stock provides a solid cheek weld and a non-slip buttpad, reducing felt recoil and helping you stay on target for follow-up shots.
• Hogue Rubber Grip — Why it matters: The Hogue overmolded grip gives you a positive, non-slip hold even with sweaty hands, which is especially helpful for new shooters learning proper trigger control.
• 9mm Luger Chambering with Glock-Style Magazines — Why it matters: Using Glock-pattern magazines (sold separately) means you can share mags with your pistol, simplifying your range bag and reducing costs.

Who It’s For

This rifle is ideal for competition shooters who want a reliable 9mm AR without the recoil of a .223/5.56. It’s also a great choice for families looking to introduce new shooters to the AR platform — the softer recoil, light weight, and easy-to-reach controls make it less intimidating. Youth shooters and smaller-framed adults will appreciate the adjustable stock and ergonomic grip.

Pros & Cons

• Pros: Accurate stainless barrel, lightweight handguard, soft recoil, uses common Glock mags, adjustable stock.
• Cons: The factory trigger is a standard mil-spec unit — some shooters may want to upgrade to a drop-in match trigger for faster splits. Also, the rifle ships without a magazine, so you’ll need to buy those separately.
