Just throwing it out there, have you guys looked into producing AIA m10 magazines in .308? Same metal mags as m14 minus the square hole in the front of mag, produced for the SMLE Enfield in .308, so Beowulf type rules apply. Last I could tell, AIA went out of business so not sure if that facilitates or makes the process more difficult, but food for thought for all the m1a/m305 shooters in canada. Capacity is 10 rounds of .308 legally.
