I took everything apart. the spring is sticking out of the magazine assembly when I put the follower back in the spring it was fairly snug and it seems i just need to crimp it onto the end of the spring.
as to the spring and follower being inside the inner magazine assembly tube. I dont see how it would be held in and judging from the picture of the replacement part it doesnt look like the spring comes crimped inside the tube. I think the spring is supposed to be sticking out a few inches so the "follower" follows the last round up to the receiver. I have never taken this gun apart before so i dont know what the magazine assembly should look like when it comes out of the gun. what does evrybody think can i just recrimp the spring onto the follower?
