Screw Fell Out of My Impact

I was shooting off my bench and had shot all I wanted for that period of time. As I lifted the rifle out of the rest I heard a plink and saw an anodized screw laying on the bench. My first thought was it came out of the scope. Nope! I went inside and started examining the rifle. I looked it over for a good period of time with no luck. As I was rotating it to put it back into the gun vise the tubular handle on the cocking lever (bolt) fell off. It was the round handle not the lever itself. I could see no holes on the outside of the tubular handle. I got a bright light and saw a threaded hole way down inside that tubular handle. The screw went through that and threaded into a place that would keep it connected to the cocking lever. A little blue Loctite and Ill probably not have that happen again. I had no idea there was a screw in there but you might want to get a light and look down in there. Get an allen wrench and check if it's secure. I was about ready to come on the forum and ask what it might be.
