It is very reliable and accurate (at least out to 200 yards, which is as far as I can see with open sights). I use composite Magpul magazines in it, and It has never jammed or failed to feed.
I have no experience with "high-end" ARs, but I definitely got my money's worth with my "cheap" High Standard.
For my next one, I'm thinking about building my own starting with an 80% lower - just for the fun and the experience.
And it’s made in TX!
For noobies, if your new rifle has hiccups after the first 100 rounds through it, try different weight buffers and put a flat wound spring in the buffer tube and you will have a gun that runs like a sewing machine. Standard guns with mid-length gas system use a 3 ounce buffer, but your gun might need something slightly heavier --an ounce or two-- or lighter if shooting heavier or lighter bullets than standard 55 grain ball ammo. ... And the CMMG .22lr conversion kits work great in the AR platform, just put a strip of one side sticky Velcro on the front of the .22lr mag where it goes up into the mag well --not on the mag well-- so the mags don't wobble around when shooting.
