Looking at a DEL-TON, Olympic (Flat Top Upper) or a BCM Upper. Whats your opinion on these three companies? Ive heard lots of good reviews on BCM's products. For the base price of a just an upper of the BCM I can get a DEL-TON with a whole kit setup without a stripped lower, with trigger and all. The Olympic upper I was interested in is the flat top with parts kid, needs barrel and lower assembly. I havent heard much about Olympic. I'm not looking for anything top quality, But I also don't want a rifle that ill have to scrap in a year. Any opinions? Suggestions? Thanks
