I stripped my HW35 and found the horrible chopped off stock spring so swapped it for a VMACH HW80 spring with guides, it wont cock now so I assume the guide or spring is too long, love to know which to save more experiments in cutting my hands...when I see kits advertised they normally say HW80/35 so I assumed all would be well.

A shame as I had a right fight getting the block back on with no tools!

Any help appreciated
