ZenitCo parts compatibility.

As an official ZenitCo dealer, we’ll provide basic compatibility information for our customers.

The heart of ZenitCo tuning is the lower handguard. Basic AK handguards are:

Any of these are compatible with STAMPED AK receivers (Izhmash, Arsenal, Tantal). Fitting milled receiver is possible, but will require filing. When you file down handguards, you should check if the fit is tight. Handguard should fit VERY tight, otherwise you can get wobbles after a few hundreds shots.

All handguards are Ultimak and Troy gas tubes compatible.

Basic out of the box compatible models:

Converted Saiga (all calibers), Vepr-FM and RPK (B-20U only), AK-74, AK-47 (stapmed), AKM (stamped), AK-105, AK-103, WASR10, Arsenal SLR 104,106,107, Tantal, Vityaz (B-21M and 21U), all Krinks with stamped receiver (B-11M and 11U).

Models that will require mods:

All milled receiver AKs (SAM7, CA C39V2 etc.), all Yugo rifles (Zastava M70, N-PAP, etc.), all Norinco rifles, AKs with Hungarian trunnion (AMD, RAS47).

B-20u WILL NOT FIT Vepr-12.

Handguards will fit airsoft AEGs made by VFC, Dboys, Cyma. LCT will require modifications. B-33 will not fit LCT AEGs.

U series handguards have only one lower rail. Side rails can be added using B-2 and B-2U parts. Screws are prodived.

When you get a handguard, you can add gas tube cover. ZenitCo gas tube covers replace standard one and are fixed to lower handguards.

B-10M, B-10U,B-11, B-11U, B-21M, B-21U, B-20U can take:

B30 can take:

B-31 and B-31S will fit all AKs with B-30, but for shorter barrel builds (e.g. AK-105) B-31S should be preferred. On short barrel builds you’ll have to remove B-31 rail for cleaning your rifle. B-31S can stay in place.

If you don’t want to replace standard gas tube cover, but still need upper rail, there are options:

Also, when you have handguard installed, you can add B-33 receiver cover for your AK. It replaces standard cover. B-33 is compatible with B-10M, B-10U and B-30 handguards. B-33 is rock solid, holds zero after multiple openings.
