I don't do steel.
I also don't do mag dumps as I consider them a frivolous waste of ammo.
FWIW, I have well over 20,000 rounds through various ARs, my SP1 is just shy of 10,000.
I bought the Sport II just to compare it to a couple of other major firearms manufacturers ARs.
BTW, it runs great. I like it and recommend it as an excellent starter AR. The only out-of-the-box issue was the spring clip on the dust cover hinge was not installed in its groove and fell off. I put one of my spares on and all was good.
Thanks

Sounds like you're doing everything right. Might double check your bolt and check out the machining work from the factory. It should be nice and smooth. "Could" have missed a step in machining and it wasn't sized to speck ?? Could just be a fluke, but something wore those rings down if they only lasted 800 rounds and it wouldn't hurt keeping a close eye on them. Keep us updated if it persists.
