PT-1 vs PT-5: Stock Compatibility for AKM, AK-74, and Civilian AK Platforms
Quick answer
For AKM and AK-74 platforms with the standard fixed-stock interface, PT-5 provides the folding configuration. PT-1 with the Non-folding AKM lock fits the same interface but remains fixed. For civilian derivatives, the manufacturer specifies PT-1 with the Non-folding AKM lock; PT-5 must not be used.
Compatibility matrix
| Platform group | PT-1 + Non-folding AKM lock | PT-5 |
|---|---|---|
| AKM | Compatible; fixed configuration | Compatible; folding configuration |
| AK-74 | Compatible; fixed configuration | Compatible; folding configuration |
| Civilian derivatives of AKM / AK-74 | Manufacturer-specified option | Do not use |
| AK-74M | PT-1 requires the correct model-specific lock; Non-folding AKM is not the selection rule for this platform | Not compatible |

PT-1 interface
PT-1 uses interchangeable locks. The selected lock determines the mounting interface. With the Non-folding AKM lock, PT-1 remains fixed on AKM and AK-74 platforms.
PT-5 interface
PT-5 has an integrated folding interface developed for AKM and AK-74. Its interface is not interchangeable and the model is not compatible with AK-74M.
Selection checklist
- Confirm the exact platform model and its rear interface.
- Decide whether the AKM / AK-74 configuration must fold.
- For a folding AKM / AK-74 setup, choose PT-5.
- For a fixed AKM / AK-74 setup or the manufacturer-specified civilian configuration, choose PT-1 with the Non-folding AKM lock.
- If PT-1 may later move to another compatible platform, select the additional model-specific lock separately.
Compatibility depends on the exact platform and lock. Do not choose by appearance or model family alone.
Frequently asked questions
Which option folds on AKM and AK-74?
PT-5. Its folding interface is integrated into the stock.
Does PT-1 fold with the Non-folding AKM lock?
No. That lock creates a fixed configuration on AKM and AK-74 platforms.
Can PT-5 be used on AK-74M?
No. The manufacturer specifically identifies PT-5 as incompatible with AK-74M.
Can the PT-1 mounting interface be changed later?
Yes. PT-1 uses interchangeable locks. A compatible model-specific lock can be purchased separately for a later reconfiguration.
