HK416a5 - selling to make room for other purchases. It has been more or less completely upgraded internally, and externally is clean with some minor blemishes:

Gate Titan Advanced (including USB link, cables)

Prometheus 6.03 tightbore barrel, new bucking and flat hopped (can include original barrel)

Upgraded spring shooting circa 350 FPS

SHS 13:1 gears

ASG Infinity 18k high torque motor

Nuprol(?) piston

The end result is something with very snappy trigger response whilst maintaining a ROF of just over 20 whilst being highly efficient with low amp draw.

A few minor niggles such as a spring being missing from the plate behind dust cover so it no longer flicks back, but can be moved manually. I have also replaced the original mag catch (as seen in pics) as the original's screw was threaded.

Comes with original magazine
