Chaser/stormrider .25 cal hybrid

Have a chaser/stormrider hybrid i built from spare parts   its a chaser  airtube cut down and rethreaded and I installed a valve and end cap on it from a stormrider/pr900w. I also installed a 10in .25 barrel and breech.  I built it to use for bench target shooting with a bottle. It has a very very small air capacity. 1 full power shot per fill at 200bar. Ir is very accurate and no pal needed as it is not over 500fps. Guaranteed only 1 in canada like this . Asking 250 or best offer. Shipping we can discuss . Trades also considered
