Even better if you could shoot them to compare. As for the HK being more solid. It is very solid but I don't know if it is any more solid that an ACR or any of the modern MSR's except the SU16. I would say it is 100% reliable. Never ever choked. I have an AR15 magwell on it just so I can get more ammo in the mag legally. Not really an issue for a DMR type rifle for someone who might be just using it for hunting. I do have .50 Beowulf mags that get me up to 16rds of 223. Just because I can. If you don't make the magwell conversion your stuck with 5rds in the HK mag, but like I said it ain't an issue for many.
Bottom line go look at each rifle and try them if you can. Then you will know what you want. In my opinion If you are going to use only 223 and your looking for the utmost in semi NR accuracy and keep the cost a bit lower then the choice is clear. SL8. Please note if your going to go blast money at the SL8 to do things like I have done (hera lower, ACR stock, AR magwell), that those things will quickly rise the cost to what the NR ACR would cost or even more. Unfortunately those items will make the ergo's better but not shoot any better.
Your not going to go wrong with either. Just don't waste your time dumping everything into trying to make an XCR accurate. There I said it. Now I duck for cover.
