Here is my question.

My BAS is shouldered. It fits into the cocking sleeve. All of the pics I've seen for the bolt lift kits would require chopping 1/2 " off my BAS, so I'm assuming there was a change to the screw. I know they went to an allen screw after this one. When did they go to a non shouldered bolt?

Would it be easier to replace the bolt with something from the hardware store, trim this one down, or order a new one from savage?
