Angry, I built my first AR in 223 and I don't even like 223. Now that I have it I want to keep the upper and find a new upper in a different caliber but that won't happen for some time. I also wouldn't mind rounding up an AR10 to add to my collection.

I was looking at this. I'd be stupid not to go this route for building it. Everything assembled and all I need to do is pin the lower to the upper.

At least build the lower. It's not hard and very rewarding.

I can't find a .308 lower for cheap enough to justify not going with that though.

It has 1-10 twist. In AR-15 language, that would be a twist rate intended for, like, 50 grain .223 rounds. But .308 rounds are often closer to three times that size (150 grains). What is the conversion equation for which twist rate(s) Angry would want to look for?

Not a bad price for the upper and lower. If it were me I would have nothing to do with the adjustable stock - having to swap that out might make assembling your own lower more attractive. For right around $1100 you can find quite a few deals on DPMS LR308's in different configurations. Check out their site - DPMS: AR-15 Rifles, Parts and Accessories. - see if you can find what you like then shop for that. I would bet a local dealer in your area can order whatever setup you want and then add on the transfer fee.

Yeah, but I can take the stock off and sell it... That stock and a standard AR-15 stock are interchangeable, right? If so, I still can't beat the price. The cheapest I've found a lower is 200, and it's on back order...
