HBI Extended Bolt Stop (Stribog)

The release tabs on our extended bolt stop are 3.5mm wider (per side), and we have extended both tabs back toward the trigger guard by 4.5mm. The flat surfaces for finger/thumb contact have been serrated for traction; all other surfaces and edges have been “dehorned” and smoothed.

This component has been through several design and validation processes, each time making careful refinements with the intention of creating a bolt stop perfect for every operator in every situation. The result is a fast and easy to manipulate control that does not interfere with the magazine release or external variables like slings/MOLLE/carriers/clothing or other gear.

Made from heat treated 4140 and finished in black nitride.

Fits Grand Power Stribog SP9A1/A2/A3. Does not fit10mm and 45 ACP Stribog models.
