Grand Power Stribog SP9A3 Locking Block - 35 Degree (9mm)

This Locking Charging Block is a direct replacement for the charging handle shuttle on the Stribog SP9A3 (delayed blow-back model). HB Industries Locking Charging Blocks are machined from high temp Delrin and feature two stainless steel detents to lock the charging handle forward while the bolt carrier is running/reciprocating (one detent on each side for reliable forward retention under recoil). They do not deform under heat from extended suppressor use and provide a smooth, positive, quiet, and reliable means by which to charge your Stribog. Compatible with all Factory and HBI Charging Handles. Designed and Manufactured completely in USA.
