hi, does anybody know what is the receiver of the sumatra 2500 made of ? is it cast aluminum or something else ?
Is there any airgun you don't know about yo?
I'd put a magnet on it to see. Use a super long wide flat head screw driver pop off that round rubber plug on the butt pad stick your screwdriver in then unscrew. The whole receiver cover in question comes right off by pulling straight up with a little wiggle fore and aft while the stock stays attached. Yo!
