The new Arsenal Warsaw stock I put on the 7.62 has a trap door-the Saiga cleaning kit goes in, but gets stuck, to get it out I have to take off the buttstock plate. There is a spring inside that the cleaning kit compresses when it goes in. All comments and suggestions to resolve problem welcome.

Are you putting the kit in the correct way? I don't have it in front of me but I think there is a sloped side and a flat side to the cleaning kit. The sloped side goes in first if I remember correctly. If you put it in backwards it will get stuck.

you are correct, but that was not the cause of the problem. I have resolved the problem by inserting a longer spring, that has more power and ejects the toolkit with ease. Thanks
