There are synthetics available from several suppliers, and Remington. I have a 20Ga Express with Adjustable LOP, that is quite handy, and allows me to quickly shorten it for the times a daughter or wife wants to go along.I have been considering a synthetic replacement stock for my 870. I have noticed on a lot of the syn. stocks the fore end looks like it is longer than my original. Will this still work on my wingmaster or do I need to go with the same size fore end?
