Eagle6 Airsoft recently completed an upgrade project for a customer's Tokyo Marui MP5 SD6 NGRS. Richard, a member of their technical team, showcased the upgraded build which underwent a range test of 65 meters with 0.30 ammo. The FPS results were impressive, with 348 FPS measured on 0.20 gr BB and 285 FPS on 0.30 gr BB.

The scope of work included an upgrade and service, with the installation of several components such as an Eagle6 M100 NGRS Spring, Psionic R Hop Patch, modded TM hop Rubber, Psionic S Nub Tensioner, Prometheus Tightbore Barrel, Prometheus Hard 18:1 Gears, Prometheus Bushings 6mm, modded FPs Piston AK, FPs Piston Head, FPS Cylinder, FPS Cylinder Head, and a Firefly Air Nozzle.

The upgraded build was tested on a 1300mah 7.4v Lipo. Eagle6 Airsoft recommends a service interval at 50K rounds, although this is optional. It's important to note that using 11.1v is at the user's own risk on any build not tested on 11.1v.

Prior to dispatch, the RIF underwent their "4 point testing" to ensure quality and performance.
