I have been searching for stocks for the builds i have going on now.....i think that the Duramax can be used for the centerfeed LA by installing the centerfeed mag into the blind mag cut out...may take some shimming and epoxy, but it is possible i think...i am going to get either a Medalist for my LA build, or a Manners ultralight . Looking at Stockade also...As for the factory stock...iv'e thought abought using a couple of graphite arrow shafts, and with some epoxy , install them into the fore end to stiffen it without adding alot of weight.....Just some options....rsbhunter
