battle rifle question
ok so im in love with my garand but i think i need to find a more modern large cal rifle that fits my lanky self . i have an ak74 (way too small ,size of rifle) , still havin a hard time gettin into the ar platform (too much plastic for my taste ) , i keep thinkin about maybe an ar with a wood set up or an fal or g1/3 type rifle and well there is always the m1a (m14) .

i guess the real question is whats the best large ,cal hi-cap (at leats 20 rounds ) ,with the most common parts and ammo rifle that you can think of ?
im just tryin to step away from the c&r thing a little and not go broke in parts and ammo , thanks for your input
