Considerations & Trade-offs
- The 3.5-lb. single-stage pull is fixed, so it offers less tuning flexibility than an adjustable trigger.
- Installation is straightforward, but the product still requires an AR-style platform built to mil-spec dimensions for proper fit.
- KNS Anti-Rotate Pins are recommended to help prevent pin movement, so some users may want to plan for that added accessory.
- The set screw should not be tampered with; any modification voids the warranty, which limits post-installation adjustment.
