I just got my second Boyds stock for my M14S and I would like to install a bipod/sling adapter in place of the front swivel.Which one (that we can get with out a lot of trouble here in Canada) is the best.Harris,etc and what are the model# to go with them?Have read a few things which suggest that possible spliting of the forend could be a problem,usually with the usgi fiberglass stock,any suggestions?
