AR-Stoner 6.5 Grendel barrel short chambered.

[XcountryRider]

I shot 5 new barrels today before I had to leave for the day. All of the uppers with Liberty Barrels fired and extracted without an issue, NONE would chamber a round all the way in so the bolt would lock by hand as being described here.. It was apparently feeling resistance.

So I put the uppers on my lower, chamber it with the bolt using the buffer spring and they all fired with the factory Hornady ammo. 2 rounds, BOOM, BOOM, cycled fine and bolt lock back on the last round for each upper.

So weather is leaves marks or not I don't know because they shot out the end of the barrel, it chambers and fires factory ammo fine.

This doesn't mean it isn't rubbing as your describing. Is it wrong? I don't know but it works.

After you break them in you can load longer out. This thing is a big panic about nothing. I'm getting nice groups at 200 yards with my barrel. I hope satern changes nothing.
