Posted this before 1000 yards NRA National LR. AR10, 20 inch barrel, 4.5X scope, sling, prone. Launching 168 Hybrids. 200-15X not bad for a gas gun. Shooter is my former teammate in TX.
Are all of these folks shooting ARs?

Who said they don't shoot???
This is a constant statement from the ney sayers. Heard it again from several folks last week. Sometimes, people just don't, (or won't) get it. Hard-headed people, take note.
No, the only gas gun is Keith's. The rest are bolt gunners
What about David Tubb? It still says miles about this subject when the #2 shooter on this who's-who list is an AR shooter! And a military brother.
Keith was picked up by the Reserves after he won the President's Hundred in 2016. Like in 1st place win among over 1000 shooters.

Keith shooting what caliber?
At 1000 yards, 308 Winchester to be a legal service rifle per NRA rules
At P100 in 2016, an AR15 223 with the barrel we chambered in my shop.

That is only true of some auto loaders. I have zero dings in my 3 AR-10's cases. you would never know that my 308 brass came out of a semi. Years ago I had a AR-15 that scratched the necks on the 223's. It was a stainless 18 inch with a SS BCG. The only thing that I could see doing it when slowly manually ejecting the empty polished cases is that the ejector was swinging the case causing it to drag across the very sharp barrel bolt lugs.
I removed the barrel and rounded/polished the chamber sides of the locking lugs and the problem was gone.
I've also see dented cases caused by short gas tube length guns. I only use rifle length and r+2 inch. Higher pressures of carbine and mid length are much more violent because of the increased pressure at the gas port. The key to pressure drop is longer and smaller diameter gas port holes. I only use the heavy full auto bolts, light flat wound springs, and the lighter buffer tube weights.
Do you use an adjustable gas block?
not on my ar-10's which are just gas guns and I run full up near max loads. Not service rifle! 308 using speer TNT 125 grain varmint bullets and TAC powder is a real pig killer at 3200 fps. I use caldwell brass catchers and blaze away at hogs on feeders from stands and quads.
I welded up some bars on my quad for a solid rest when you pull up to a field. We had a dusting of snow yesterday. I can strap on 3 ar's on the bars in soft cases like for squirrel and PD days.
I only have adjustable gas blocks on my piston ar-15's. I've always use the smaller steel gas blocks for what ever diameter barrel. I grind a dimple for the set screws so the blocks won't move.
I have an Adams and two Superlative arms rifle length pistons kits and both of them have failed out in the wilds from going out of adjustment after hundreds upon hundred of rounds. Then you have muck with them if they haven't lost a screw or something
adjustables are just another point of failure compared to non adjustable. You just have to put some thought and change the weights of items to get YOUR ammo to cycle right and all the rounds landing out there at 2:30. No reason to use an adjustable. spend you money on SS match grade barrel and specify smal diameter gas holes with rifle or rifle + two inches
