The battery assist device is a must have accessory for any Rock River AR15 owners. We recommend the Magpul BAD Lever

Faster Reloads - This device speeds up the reloading process by extending the bolt release paddle to the rifle's right side, enabling the trigger finger to operate the bolt from the fire control/ready position.

Enhanced Manual of Arms - It significantly improves the speed and efficiency of weapon manipulation and malfunction clearing.

Single-Handed Operation - You can lock the bolt to the rear using your index finger without needing to release your grip on the pistol grip.

Reload when you want to, NOT when you have to! If you have to then use this to do it faster!

Raptor Charging Handle - Increased Durability & Ergonomics

When upgrading your Rock River Arms AR15, whether it's left-handed or right-handed, consider adding the Raptor charging handle.

Ambidextrous - It allows you to charge the Bolt Carrier Group (BCG) from the right side during shoulder transitions.

Troy Enhanced Trigger Guard - Works Better With Gloves

Troy Enhanced Trigger Guard SGUA-AMB-00BT-00

If you wear gloves while shooting, a larger trigger guard is essential to accommodate the gloves. It works especially effectively during the winter season.

Upgrading an entry-level Rock River Arms LAR 15M, especially one with the old-school plastic handguard, by adding a modular 6061-T6 Aluminum handguard can bring about a significant transformation in both its appearance and tactical capabilities.

Available for 9.3", 10.5", 13.5". A2 front sight must be removed first and low profile gas block is required for installation.

M LOK Compatible - Mount any MLOK accessories like lights, laser, and grips you want at the 2, 3, 5, 6, 8, 9, 10, and 12 O'clock positions.

Rock Solid Receiver Lock - An anti-rotational tab ensures a secure connection to the upper receiver, preventing any shifting.

Heat Resistant - Full rail slot cuts reduce weight and enhance heat dissipation, ensuring the handguard remains cool even during extended use.

Thick Barrel Nut - The barrel nut boasts a long cantilever beam design, holding the handguard firmly and preventing flex or wobbling along the bore.

It Keeps The Handguard 100% Locked In

Magpul CTR Stock - Eliminates Wobble

Many LAR15 models come equipped with the standard stock. We strongly recommend upgrading to the Mil-Spec models like the Magpul CTR stock or the Magpul ACS.

Low Drag & Snag Free - A high-quality stock enhances the Rock River AR's performance by reducing drag and preventing snags, making it more efficient.

Added Sling Attachment Points - These stocks provide the flexibility to use various push-button QD sling configurations according to your preferences.

Reduced Wobble - Unlike the standard stock, these options offer a rock-solid fit, eliminating the annoying wobble commonly encountered. This added stability improves the rifle's positioning on the shooter's shoulder.

Recoil Reduction

Surefire MB566 Muzzle Brake - Mitigates Recoil


Enhance your shooting experience by replacing the standard A2 birdcage muzzle device with the Surefire MB566 muzzle brake! This simple upgrade can have a profound performance boost impact:

Reduced Muzzle Flip and Muzzle Rise - The MB566 significantly reduces both muzzle flip and rise, allowing you to quickly follow up with shots on target.

Minimized Side Blast and Rearward Concussion - This muzzle brake also minimizes side blast and rearward concussion effects, making shooting more comfortable for the shooter.

Suppressors Compatible - It's compatible with Surefire suppressors, featuring multiple bearing surfaces to ensure superior alignment with the suppressor can.

bcm vertical foregrip

If you have upgraded to an M1913 railed, MLOK or KeyMod handguard, the BCM Gunfighter grip is our favorite.

Enhanced Grip Ergonomics - Drive the muzzle faster to the target with an rock solid grip on the rifle and to operate a weapon light at the same time.

Reduced Sway -  C clamp grip helps reduce sway by providing better grip leverage

Way Better Recoil Control - Reduce horizontal and vertical muzzle recoil shifts for faster follow up shots (Helps even more if using a muzzle brake)

It Allows You To Shoot Fast & Have A Great Time!

Geissele Super 42 Braided Buffer Spring - Improved Spring Service Life


While the default Rock River Arms buffer tube is serviceable, we recommend upgrading to the Geissele Super 42 Braided Spring, along with an H1 or H2 buffer for a 16" standard gas system.

Increased Cycle Life - The spring operates at only about 35% of its maximum stress load, greatly extending its service life. The springs flex independently, similar to a harmonic damper and energy absorber, which helps displace excess energy, preventing failures.

Improved Reliability - The braided wire design enhances bolt return force, ensuring reliable round chambering, even in challenging conditions such as when using dirty or steel-cased ammunition. Additionally, it helps eliminate the annoying "twang" sound and extends the spring's longevity.
