The proof of the pudding is in the eating, as you might say - when I have the gun, I will post a picture of the slot in the standing breach to confirm Lovel's statement.

This is largely beyond my ken, but I did notice that the top surface of the locking part of the extension is not flat but is angled up left to right. If the fastener cams, wouldn't it be better to have the bearing surface angled slightly up to increase the downward pressure as the cam moves across the extension? Or would an angled bearing surface be used regardless of the type of fastener used to hold the extension down?


Such a long, long time to be gone, and a short time to be there.
