The AK's weak spots are the same on every rifle: no rails, nowhere good for an optic, and a handguard that gets hot.
TDI X47 Universal: Rails Everywhere
The TDI X47 Universal is a machined aluminum system with five Picatinny rails, including a rear rail built to hold heavy optics. It fits milled and stamped AKs (not Yugo), installs without a gunsmith and weighs about 420 g.
Best for: an AK that will carry a real optic, a light and a grip.
FAB Defense Vanguard AK: Light and Cool
The FAB Defense Vanguard AK is a slim polymer M-LOK handguard with an extra heat shield, M-LOK slots around the clock, and no gunsmith needed. It fits standard AK-47, AKM and AK-74.
Best for: a lighter rifle with a light and a grip, where comfort matters most.
Optic Without Replacing the Handguard
The FAB Defense PDC-AK dust cover gives you 185 mm of Picatinny rail on top and keeps your iron sights usable. It doesn't fit Yugo / Zastava rifles.
Zastava Owners
Zastava M92 and M85 get their own option: the TDI Z92 lower M-LOK handguard, compatible with the Ultimak gas tube rail.

- Grip: CAA UPG47, FAB AGR-47 or the reduced-angle FAB GRADUS.
