The Delta Armory QRS B5 pistol grip is designed for M4 / AR15 AEG rifles and combines modern ergonomics with practical features for both everyday gameplay and maintenance. The main advantage is the integrated QRS (Quick Release System), allowing you to remove the motor quickly and without tools, which significantly simplifies servicing or motor replacement. You will especially appreciate it during quick field repairs when your rifle suddenly stops firing due to a loose motor connector. The grip body is made of durable polymer, keeping it lightweight yet strong enough for demanding use. The ergonomic shaping provides a natural grip, better weapon control, and comfort during extended shooting. An ideal upgrade for players who want easier maintenance and improved handling. Grip screws are not included; use the original ones.
Yes, it is designed for standard M4 / AR15 AEG platforms following the TM standard. It fits most brands without issues, although minor fitting adjustments may be required on some atypical receivers. Always check the motor angle alignment with the bevel gear.
QRS refers to the tool-free base plate release mechanism, allowing easy motor access. You can quickly fix a loose connector or swap the motor for a stronger one, for example when preparing for a semi-only event.
