GP Stribog A3 Locking Charging Block (SP9/10/45)

This Locking Charging Block is a direct replacement for the floating charging handle shuttle on your Grand Power Stribog (SP9A3, SP10A3, and SP45A3). Our Locking Charging Blocks are machined from high temp 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. Please use the drop down menu to select from 9mm or 10mm/45acp. NOTE: This product is not compatible with SP9A3S (short) models as the upper receiver is not long enough to retain the locking detent.
