I just bought a M1A Scout..I figure this rifle will never see more than 6000 rounds ever prob....I will use it as a duty carry rifle. I didn't really want to have to put GI parts in it per say, but i also want a AK reliable rifle....I've read that i can change to a GI extractor. with this done what benefit would i have to going with a GI bolt,op rod or trigger system?? Ive thought about doing this, but the 600 or 700 cost seems like it be better spent on ammo??? thanks for any help.
