I know this sounds stupid, but how in the heck do you remove the bolt handle from the bolt on this thing? Manual says "remove the bolt handle with a firm tug". My a**!! I've tried pliers and visegrips, pulling from various angles, twisting, etc. This thing will not come out! Any suggestions? Otherwise, this thing looks very simple to dissassemble. BTW,it is the original factory handle. Thanks for any help!
