Compatibility hierarchy
| Configuration | Required interface or components | Fit result |
|---|---|---|
| Compatible handguard | Lower Picatinny rail | Direct installation |
| Zenitco B-9 bracket | B-9 Picatinny output | Direct installation on the bracket rail |
| PKM or PKP, one angled RK-2 | B-50 + B-25U | One RK-2 positioned at 45° |
| PKM or PKP, two angled RK-2 grips | B-50 + B-25P | Two RK-2 grips positioned at 45° |
Selection checkpoint: RK-2 requires Picatinny. It is not the Basis-interface RK-2L. For the documented PKM/PKP angled configurations, select the complete adapter route shown above.
Why choose RK-2
The full-length profile provides the largest contact area in the Classic RK series. The machined body is offered in Black, Desert and Golden khaki, while the sealed compartment keeps small compatible accessories protected inside the grip.
