Overview
Designed for double-stack magazine setups, this spring is intended to support a lockback solution when paired with the Atlas Lockbak Follower and a lockback slide stop, which are not included. It is made to fit 120mm and 126mm magazines, with the +15% version suited to 120mm/126mm use and the +18% option intended for 126mm/140mm magazines. For shooters setting up compatible magazines, it offers a focused replacement part rather than a general-purpose spring.

Considerations & Trade-offs
- Designed for use with the Atlas Lockbak Follower and a lockback slide stop; it is not a standalone fix and the follower is not included.
- Fitment is limited to 120mm and 126mm magazines, so it is not a universal option across all double stack setups.
- The +15% version is positioned for 120mm/126mm magazines, while the +18% version is intended for 126mm/140mm magazines, so selecting the wrong spring can create a mismatch with your magazine length.
- Because the product is offered as a spring only, any complete lockback solution requires the compatible components specified by Atlas Gunworks.
