[QUOTE="TRG65, post: 2677743, member: 103919"] I built my upper using a heavy billet side charger from brownells, forget the brand. I used a 20” proof barrel. If that is your barrel choice be sure to get a jp bolt. I tried a brownells bolt and it really didn’t match up well. Also I tried a jp spring system and light weight bolt that didn’t work reliably. Great for 223 not so much for 6ARC. I ended up with a tubbs spring, h1 buffer and a full mass carrier. I’m running a slr adjustable gas block. Since I played with the buffer system I haven’t reset my dies, but with the light system I had to resize my Hornady brass 10 thousandths, with in my opinion is way too much for reliable cycling. I have not had great luck with my handloads. I’m only getting 2530’ish. That was a node across multiple powders. I managed to push to 2600 but it was showing pressure and over 2600 I popped some primers. In the summer, I saw 2700 with factory, but it was leaving bad ejector marks. All that said, I like the arc. It does everything I want from an AR better than 223. But it has been very a challenge to get all the bugs worked out for a rifle that can do both some competitions and some hunting. But it and my 6.5Creedmoor AR 10 are the ones that get shot the most. [/QUOTE]
