When using QSC quick-change spring pins in mechaboxes, the QSC spring pins may be incorrectly adjusted in some rare cases. This problem is rare, especially in mechaboxes (e.g. AK) that do not have the spring mandrel bolted to the stock (e.g. M4, etc.).
This locking bolt eliminates this problem completely and allows the use of QSC quick-change spring arbors without any problems.
The locking screw is made from C45 material (12 050 steel) on a CNC machining center. Surface treatment by brizing (chemical blackening). There is an external thread M5 on the bolt.
Tightening is done with a flat head screwdriver or a coin.
