HB Industries Grand Power Stribog SP9A1 Locking Block

This Locking Charging Block is a direct replacement for the charging handle shuttle on the Stribog SP9A1 (direct blow-back model). Our Locking Charging Blocks are machined from high temperature Delrin and feature a stainless steel detent to lock the charging handle forward while the bolt carrier is running/reciprocating. Our Charging Blocks do not deform under heat from extended suppressor use and provide a smooth, positive, quiet, and reliable means by which to charge your Stribog. Locking Charging Block for Grand Power Stribog SP9A1 Drop In Replacement for Factory Charging Shuttle Compatible with all Factory and HBI Changing Handles Machined High Temp Delrin Block Stainless Steel Detent Designed and Manufactured completely in USA. Note: This charging block is not compatible with early "Gen 1" reciprocating charging handle models. This charging block will only fit "Gen 2" Stribog SP9A1 models with non-reciprocating charging handles.
