Atlas Custom Works MMS 10.1" Handguard Set for Tokyo Marui AKM GBB, Black

If you're running a Tokyo Marui AKM GBB, the stock handguards are the first thing you'll want to change. They're polymer, they flex under a rail-mounted light, and they don't give you much room to work with. The Atlas Custom Works MMS 10.1\" handguard set swaps those out for CNC-machined aluminum with a full-length top Picatinny rail and M-LOK slots on the sides and bottom.

What you get. The set includes the upper and lower handguard pieces, both machined from aluminum with a black anodized finish. The 10.1-inch length extends past the gas block, giving you plenty of real estate for optics, grips, lights, or lasers. M-LOK slots run along the 3, 6, and 9 o'clock positions for modular accessory mounting, while the top rail is continuous for scopes or iron sights.

Fit and installation. This is designed specifically for the Tokyo Marui AKM GBB platform. The clamping system locks the rail assembly down without wobble, and the open cutout pattern reduces weight while improving airflow. You'll need basic tools to swap the handguards, and the job takes roughly 15–20 minutes if you're familiar with AK disassembly. If you've never taken an AKM GBB apart, budget an hour and watch a guide first.

What it's not. This is a handguard set, not a complete upper receiver. It does not include a barrel, gas tube, or mounting hardware beyond what's needed to attach the rails to the existing gas block. You're upgrading the externals and accessory mounting, not the gas system or barrel.

Handguard only. Installation hardware and tools not included.
