I have followed dis\assembly instructions as per my manual 5 times now and each time the result is the same. The bolt will not operate without extreme force. The rails require extensive fiddle####ing to ge them where they need to be. My springs are pretty much ####ed as they just bind up everytime I attempt to cycle it. What am I doing wrong? I am really at the point of just parting this POS out. I have followed instuctionsto the T, it's gotten me nothing but wrecked springs.
