Custom airsoft VSR 10 Gspec 465fps (Marui based - PDI upgrades)

Hi there, Here is a short video of my custom Marui VSR10 Gspec sniper rifle. All internals are PDI. The rifle shoots at 465fps. It shoots with incredible accuracy and it's also reproducible. Lot of work and adjustment were done but the result is above expectations !! In the video, tests = head shots at 45m (150ft), body shots at 70m(230ft). My current record = hit target at 90m (295ft).
