- description
Version 3 shells are what AK and G36 pattern guns run, and the small springs inside them differ enough from a Version 2 that the sets are sold separately.
As with any mechanism spring, the trouble they cause is subtle. A cut-off lever that does not reset cleanly gives you the occasional extra round on semi, which is the sort of fault that gets blamed on everything else first.
Keeping the correct set for your shell on the bench saves guessing when something in the mechanism feels lazy.

Buy for the shell you actually have. Version 2 and Version 3 sets are not interchangeable.
Frequently asked questions
Can I use a Version 2 set instead?
No. The two shells use different mechanism springs, which is why they are sold as separate sets.
Which guns run a Version 3 gearbox?
AK and G36 pattern builds are the common ones, though other platforms use it too. Check before ordering if you are unsure.
What does a tired cut-off spring feel like?
Usually an occasional extra round on semi-automatic, or a trigger that does not reset with the same crispness every time.
