Page 54 shows the front assembly. I do not have the front sight, only the bayonet base that is held on (?) by the taper pins. It looks like the base holds the hand rail cape in place. I have looked at picaninny front sight rails, And a three d view seems to indicate that the bayonet base must be removed and the front site rail takes place of the bayonet base to hold the hand rail cap in place. Does it look like it to you? Thanks for the quick reply! Much appreciated!
