Personally I would more favour the HW95 or 85 if you can find a good un!. The '80 is a lovely rifle but is more suited to FAC energy levels or sleeving down the piston (i.e. Venom http://smg.photobucket.com/user/Airs...ml?sort=6&o=58) or shortening the stroke if you want it in sub 12ft.lbs. Why carry round that extra weight when the '95/85 does just the same job?
