What caliber(s)? If you're still looking, fairly recently I got a 204 Ruger complete upper from ar15parts.com. Shaw barrel 20", stainless medium profile,1/12. Very satisfied, super accurate, fit and finish of all parts are top notch. Quick ship also. I was so satisfied with them I just the other day received the 24" Satern 223 Wylde barrel I ordered, but this one is 1/8 and heavy profile. But it shoots even better than the 204. Groups touch at 150yds with 75gr over 22.4 gr of H322. I'm going to use this one from now on for coyotes as this year I had to chase a couple that I hit with the 204.
