magpul bad lever

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

Reload Way Faster - The battery assist device cuts down the reload speed by extending the bolt release paddle to the right side of the rifle, allowing the trigger finger to operate the bolt from the fire control / ready position.

Improved Manual Of Arms - Significantly improved the speed and efficiency of weapon manipulation and clearing malfunction.

One-Handed Operation - Lock the bolt to the rear with the index finger without getting off 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

The raptor charging handle should be added to any AR during the upgrade process.

Ambi -  Charge the BCG from the right side during shoulder transition

Increased Durability - Charge it hard without shearing the handle over time unlike the one out of the box 

Much Larger Latch - Easier to grip & palm blade on the serrated big latch

Makes Manual Of Arm & Clearing Malfunctions So Much Easier

Troy Enhanced Trigger Guard - Works Better With Gloves

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

If you wear gloves when shooting, you need a bigger trigger guard to clear the gloves. Works very well in the winter!

geissele mk16 handguard


For an entry level Rock River Arms LAR 15M with the old school plastic handguard, adding an modular 6061-T6 Aluminum handguard will change the way the rifle looks and its 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 - Anti rotational tab holds on to the upper receiver from left and right to prevent it from shifting

Heat Resistant - Full rail slot cuts reduces weight and maximize heat dissipation

Thick Barrel Nut - Long cantilever beam barrel nut design holds the handguard tight and sturdy along the bore, and doesn't flex or wobble

It Keeps The Handguard 100% Locked In

Magpul CTR Stock - Eliminates Wobble

magpul CTR stock black

Most LAR15 models come with the standard stock. We highly recommend the Mil-Spec model the Magpul CTR stock or the Magpul ACS.

Low Drag & Snag Free - A high-quality stock transforms the Rock River AR into a low drag, snag-free carbine

Added Sling Attachment Points - Use any push-button QD sling configuration as you like.

Reduced Wobble - This rock-solid stock eliminates the annoying wobble typically experienced with the standard stock, and it stabilizes the rifle better on the shooter's shoulder.

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

Geissele Super 42 Braided Buffer Spring - Improved Spring Service Life

braided-buffer-spring

Eliminated Spring Twang Sound - The braided wire spring kills the annoying twang sound and preserves spring harmonics inside the buffer tube.

We recommend the Geissele Super 42 Braided Spring with H1 or H2 buffer for 16" standard gas system

Increased Cycle Life - The spring operates ONLY at around ~35% of its maximum stress load to increase its service life. The springs flex separately from each other like a harmonic damper and energy absorber to displace excess energy to prevent failure.

Improved Reliability - The Braided wire increases bolt return force to ensure proper round chambering when dealing with a dirt or steel case ammo
