<p>I just took apart a cranky A12 back to lube and grease it and everything is running super smoothly. The only issue is that the crank mount won't 'catch' on the gear inside the back to allow me to wind the back.<br>
I <em>think</em> the issue is with the little spring pictured <a href="http://imgur.com/a/eRoVL">here</a>. There is no tension in the little arm because the spring seems to be in the wrong position. But I don't have any empty magazines to double check against.<br>
Has anyone ever had this issue? Any solutions?<br>
Thanks!</p><div></div>
