I am not an expert but if it was me I would definitely put in a 03-A3 triggerguard and get the "correct" stock. After all it IS a 03-A3. That C stock looks to me to be worth at least $200.00, and the 03 triggerguard as a complete unit about $$50.00-$80.00, maybe more. Get a W.W.II style web sling and the cleaning kit for the butt trap, plus a nice W.W.II bayonet (probably the short blade one) and you are all set!
