I'm working on a 110 L-D in .243 and need to put a new stock on. I have never worked with the older 110s and the "L-D" is proving to hard diagnose as to what stock it needs. I know the "L" stands for 'left" but what does the "D" signify? I'm looking to put a Boyd's thumb hole stock on and I am unsure as to which one to buy. Any help would be greatly appreciated.
