No weight limit but you will not want to be too heavy for your own sake. 28-30" barrel of Medium Palma contour or so. Without the weight of bipods your rifle/scope weight will probably be in the 12-14 Ib. range. Your Manners could be modified I suppose (forend rail if not so equipped, adjustable cheekpiece and butt plate). If you are going the conventional coat and sling route you will want good iron sights as well as most of the matches you will be shooting will have iron-only components to them. The learning curve is a bit steeper than other classes but you will learn a lot and appreciate what you have accomplished in the end.
