Does it make much difference if your build utilizes matched receivers. I'd like to build the best quality rifle I can without the benefit of a full machine shop, but I'm not sure how much better / accurate it'll be. Am I just wasting money I could have otherwise spent on other components? Thanks for any opinions and / or guidance here.

I have never really tested it out but unless the fit is so sloppy that things are clanking around and messing up your trigger squeeze I can't believe it makes any difference.

Rock River used to sell matched sets of upper/lower, I don't remember them as being a real steep increase over the cost of non matched sets so If it concerns you start your build with that.

Sometimes going the extra step be it in builds,reloading or whatever just is the icing on the cake as far as building confidence. Not likely to have any real solid results in the end but is just one less thing to worry about

There are FAR more ARs built without "matched" receivers than there are with "matched" receivers. I've played around with mating different lowers with different upper combinations and found some differences with regard to slop, which could be expected, but I have not found a combo that failed to mate. Check out the Accu Wedge. It takes care of any slop.

Thanks for the feedback. I think it would be unnecessary overkill for almost all applications. I appreciate your opinions.

I'm going to go out on a limb and say that a "matched" set means that those uppers and lowers were anodized in the same batch so the color matches and that the set was milled around the same time frame by the same supplier/forge. They may go the extra step of checking fit to find the tightest tolerances. I'm sure higher end names go that extra mile to assure satisfaction.
