Item Description:

NOTE: This product is not compatible with SP9A3S (short) models as the upper receiver is not long enough to retain the locking detent.

This Locking Charging Block is a direct replacement for the charging handle shuttle on the Stribog SP9A3 (delayed blow-back model). Our 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). 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.
