Kalashnikov RK-0 D16T Alloy Tactical Vertical Grip, Black

Recoil control on a GBB rifle or a kicky AEG boils down to where your hands are. A vertical grip puts the dominant hand in a position to drive the muzzle straight rather than fighting the torque.

The RK-0 is CNC-machined from D16T aluminium, a copper-alloyed grade built for load-bearing parts. It weighs 4.8 ounces, which is enough mass to add damping without turning your forend into a deadweight. That difference from a polymer grip is something you feel during sustained full-auto bursts or rapid semi strings.

The profile is compact. It sits forward on the rail where it won't catch on sling cables, pressure switches, or your support hand during transitions. The Picatinny mount clamps square and holds that position when you remove and reinstall it, which matters if you run multiple accessories across the same rail.

Inside the grip body is a sealed storage slot. Small enough for a coin cell battery, a hex key, or a couple of spare O-rings, and it stays closed when you drop your rifle in a puddle. Not a replacement for a pouch, but genuinely useful for the one or two things you want on the gun.

It's a vertical grip. That's the whole job. Mount it on any rifle with a Picatinny forend rail, get a thumbs-forward index, and you're done.
