Description
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.
- Locking Charging Block for 9mm, 10mm, and 45ACP Grand Power Stribogs
- Drop In Replacement for Factory Charging Shuttle
- Compatible with all Factory and HBI Changing Handles
- Machined Delrin Block

Buttery smooth charging on the A3, and the detent has that perfect ‘snick’ into place to keep it forward. A+

Easy to install. The block is well made and works great. Very fast shipping from HBI.

A no-brainer. The factory part is cheap and this is a functional improvement that should have been an OEM part. Just get it.

Accidentally purchased this for SPA3S. The detent sticks out past the receiver and would probably work as is. I decided to mill it down so it no longer has the detent and does not stick out past the front of the receiver. This is an upgrade from the oem block and I don’t have to worry about warping due to heat. Hopefully HB offers this option in the future for the SPA3S. I could only one other manufacturer of a upgraded block which was aluminum and most definitely have the self lubricating properties as the HB part.

This thing make a big difference. My wife pretty much couldn’t charge the gun until I put this in . Very smooth, maybe the best upgrade I’ve ever done !
