thanks chip. we can only get the most basic support for these rifles in the UK, the gunsmith that did some conversions and tuning parts went out of business. i got a few spares and a target stock from archers and it was cheaper than getting parts here. my rifle is a working gun so its not as fancy as yours, i just sprayed it matt black and touch it up as it gets beat up. (the stock is for tiny little chinese guys, i had to put 1.5" spacers on the buttpad to give it a 14" reach so my son and i could use it, and its still short for me. i got a bipod for it but the stock is so short i'll have to figure out how to barrel mount it.
mine is the '79 that uses 88g gas bottles or a paintball bottle but these are so expensive here i put a paintball quickchange in it to use a single 12g, get around 30 usable 40yd rabbit shots out of it, 40 for squirrels or rats closer up.
