Weird cycling issue... thoughts?

Have you tried any quality factory rounds, to eliminate the gun -maybe?

I rarely shoot factory, but for the 25ish factory rounds I've had through the upper they've been problem free. Small sample though

This past weekend I took a low round count course

The ammo I was shooting was a handload of mine

There's your problem, and why many courses (all the good ones, JMO) prohibit using handloads/reloads.

Everybody ends up fiddle ****ing around wasting class time trying to determine what's wrong with their ammo

My money's on the ammo being the problem.

Even if it's the ammo, doesn't mean that a chamber brush won't help. Have you been shooting steel or using any 22lr conversion kits?

It could also be the BCG itself sticking. That's pretty classic NIB behavior, and the fact that you were able to unlock it so easily makes me think that might be it. It seems like when cases get stuck they get stuck good.

A lot of guys don’t know how to make handloads for ARs. I took a KD4 course with handloads, though not recommended, but I’d fired thousands of them through my rifle. Not a single hitch the entire time.

Check your hand/mortar ejected Bullets for rifling marks. When I had this issue, I needed to add crimp; the Bullets were jumping forward when they were fed into the chamber and hitting the rifling.

When I set a crimp, I do a chambering test. Single round in the mag, drop an open bolt on it 3 times. If it gains or loses more than 0.002”, I tighten the crimp. They still shoot ragged holes so it works for me.

Bull crap.

If NiB coatings were doing the garbage you suggest with ANY sort of regularity it would be all over the web and everywhere else but it is not...

How many reputable companies offer NiB now and for how long have they been doing so with none of the 'problems' you suggest being reported?

Your lack of knowledge and facts here are what keep the myth going for dummies that blindly believe everything they read on the internet.

It is. Google "nickel boron bolt sticking." This ain't new. Not by a long shot.

Not going to lie, my buddy has a NiB Fail Zero bolt carrier group in his rifle. We called it the “Fail Often” until he has the cash to replace it. It indeed would stick. I didn’t know it was a thing known about them or even caused by NiB, but his did it.
