My DA never thought of going to same manufacturer as the lower. That is definitely the best thing to do to get this thing together. Hate to hear that one Delta since I bought that yesterday. Is it poor quality, CS, or both? What's the reputation of diamondback?

Ive searched and read several different things and and have ended up more confused than when I started. I've built a few different ar-15's and this is my first AR-10 build. I need some help/guidance. I'll admit, it's it's different animal. I've learned that the stripped lower I purchased is only compatible with armalite uppers. Are there any armalite alternatives that have the same fit? If I purchase a stripped armalite upper can I fit other brand rails, barrels, gas blocks, etc on it? Here is what I have: Diamondback stripped lower - multi cal I've purchase a lower kit from delta and am confident it's compatible. I appreciate your help!
