Sorry for the poor quality of the photo. I just purchased this gun and I'm getting ready to do a complete cleaning. Can someone explain to me the purpose of the two machine screws that appear on the forend assembly? Thanks for your help.

They connect the metal to the wood and some were a #4 screw 1" long but not tapered. There were a few different styles, one that had a tip that was turned smaller and had a round nose to act as a guide. These were shorter.

I think that the ejector forends all had the 1" wood screws and I've seen extractor forends with both types as David described. I much prefer this screw pattern as the forend is fastened in both directions. We've all had problems with the rear screw pulling loose from the wood over time

Thank you. I will proceed with caution.
