This is a factory screw up. It is a cosmetically challenged GKR-10MS MLOK rail. It carries no warranty.
The GKR-10MS is a 10″ drop-in fit MLOK rail for Bulgarian SAM7 and most 1.0mm stamped “AKM style” Kalashnikov rifles with short-style sling loops (not full length or tall loops like East German or Yugo)
It mounts similarly to the factory handguards, you will need a factory style front handguard retainer
You can add your KVAR style stainless heat shields for added protection, and you can use your factory cleaning rod
Weighs 5.9 ounces with all hardware included
Minor fitting may be required
IS NOT COMPATIBLE with other types or makes of rifles at this time. Does NOT fit PSA rifles due to their unique cast front handguard retainer.
