I built a poor mans faux M40A1 but I used a long action 110 since that was all I had. Turned out nice. I'll try to post some pics tonight.
If you build one and use an HTG I recommend a scope that you can mount low, the HTG stock has lots of drop. Also if your're using the rifle for hunting and plan on using a lighter contour barrel, the stock may look a little goofy.
