Ca m24
I have had my M24 for years. I've decided to upgrade the spring to get 450+ fps. I have all PDI parts inside of her. So I put in a new APS2 150 spring. I can fire it once then It won't cock! I noticed the spring that I pulled out of her was a lot thinner coil? Should I be using an AEG spring or an APS2 spring? Thanks
