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:
- B-10M (AK)
- B-10U (AK, with optional side rails)
- B-10L (AK, ultra lightweight, all rails are optional)
- B-11 (AKS-74U Krink)
- B-11U (AKS-74U Krink, with optional side rails)
- B-21M (9×19 PP-19-01 Vityaz, KP-9 and Saiga-9)
- B-21U (9×19 PP-19-01 Vityaz, KP-9 and Saiga-9, with optional side rails)
- B-21L (Ultra lightweight 9×19 PP-19-01 Vityaz, KP-9 and Saiga-9, all rails are optional)
- B-20U (7.62 or 5.45 RPK or RPK based Vepr-FM, with optional side rails)
- B-30 (AK long handguard)
- B-30U (AK long handguard with optional side rails)
Any of these are compatible with STAMPED AK receivers (Izhmash, Arsenal, Tantal). Fitting milled receiver is possible, but will require filing handguard. 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 and KP-9 (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.
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-10L, B-11, B-11U, B-21M, B-21U, B-20U, B-30, B-30U can take:
B-30 and B-30U can take:
B-31, B-31N and B-31S will fit all AKs with B-30, but for shorter barrel builds (e.g. AK-105) B-31S or B-31N 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.
B-21L can take B-19, B-19N or DL-2 extender with B-31LV or B-31LN long upper rails (for long barrel KR-9).
If you don’t want to replace standard gas tube cover, but still need upper rail, there are options:
- B-22 (mounts over iron sight on B10M, B10U, B21M, B21U, B30 or B30U). Doesn’t block iron sights.
- B-18 (AKS-74U SBR type, mounts over iron sight).
- Elongated B-18U
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, B-30 and B-30U handguards. B-33 is rock solid, holds zero after multiple openings.
There are also ZenitCo side mouns:
