More upgrades to my Baikal MP654K

I have added a new brown “star” grip and an upgraded internal part.
parts upgraded/changed:
grip
valve (Benz valve)
magazine head (with groove and BB centering screw)
barrel nut (to fit grooved head)
seal (to barrel nut)
valve spring (slightly weaker spring)
valve assembly (larger internal area to hold more Co2)
All items purchased through Ebay (usually from Russia)

Have done a these mods and upgrades. Increase in power is bugger all. Parts aren’t cheap either! Still a nice gun,

The valves are bore up or replaced with mercy holes, and are the valves replaced with those that are more flexible?
