Upgrade Kit: AR-15/AR-10 Reduced Power Trigger Spring Kit + 2 Anti Walk AR-15/M16 Receiver Pins
The TF Tactical Anti-Walk Pin Set and Reduced Trigger Pull Spring Kit from Delta Team Tactical is an AR-15 lower receiver upgrade designed to improve reliability, trigger performance, and overall accuracy by combining steel anti-walk hammer and trigger pins with a reduced-power spring kit. Designed for standard .154 diameter receivers, the anti-walk pins help prevent trigger and hammer pin movement during use while also reducing wear on the receiver’s pin holes, with durable steel construction and a nitride finish for long-term performance. The included reduced trigger pull spring kit replaces factory springs to lower trigger pull weight from roughly 9–10 lbs down to approximately 4.5–5.5 lbs, resulting in a smoother, more controllable trigger press that can improve practical accuracy while still maintaining reliable ignition with hard primer ammunition such as 7.62x39 and 5.45x39.

- DIY gunsmiths performing lower receiver enhancements
- General range, defensive, or competition rifle improvements
Anti-Walk Pin Set
The included anti-walk pin set is designed to secure the trigger and hammer pins within the AR-15 lower receiver, preventing lateral movement during firing cycles. This helps maintain consistent fire control group alignment while also reducing long-term wear on the receiver’s pin holes. Manufactured from steel with a nitride finish, the pins provide durability and corrosion resistance for extended service life.
Reduced Trigger Pull Spring Kit
The TF Tactical reduced trigger pull spring kit replaces standard factory trigger springs to significantly reduce trigger pull weight, improving overall trigger feel and shot control. By lowering pull weight into the 4.5–5.5 lb range, the kit helps shooters achieve more consistent trigger presses and improved accuracy. Despite the reduced pull weight, the springs are designed to maintain reliable ignition, including use with harder primers found in select rifle calibers.
Performance-Focused AR Lower Upgrade
Together, the anti-walk pin set and reduced trigger pull spring kit provide a straightforward yet effective lower receiver enhancement. This combination improves both mechanical stability and trigger responsiveness, making it a practical upgrade for shooters seeking better performance without a full fire control group replacement.
