turn gasblock to fire AR10 single-shot

[sansone]

thinking of removing gas tube and turning the gasblock to eliminate gas system while working up a good load. Anyone else feel this will help by removing the gas system from the equation? We use lead sleds, target scopes, voodoo cleaning rituals, everything to eliminate variances when testing loads for accuracy. What about eliminating the gas too? of course when the magic load is found return to gas system

But isn't how the round is loaded/fed into the chamber another variable that affects accuracy?
I'd load the mag up and shoot it as you normally would in the field. You want the gun assembled as close to your actuall use in the field. You're baselining your working setup. Removing the gas system would be different than what you actually use. Probally counterproductive.

You want to reduce variables, not add another.

You paid good money for a SEMI-AUTO rifle.

Now, you want to convert it to an awkward single-shot on the shaky premise that it MIGHT deliver better accuracy that way. So, do you intend to keep it as a one-shooter? I can assure you that, whatever results you obtain with the rifle as a single-shot, it will NOT deliver the same results if it's reverted to semi-auto function.

Do the load development in the rifle's original (and proper) semi-auto condition. If you need a super-accurate shooter, you may want to buy a good bolt-action....but the AR-10 may surprise you!

1. Don't do it.
2. Buy a bolt action.

So, you want to change your rifle to find a load, in the hopes that it will still shoot the same after you change it back? I'm with Bruce, in that it will not shoot the same before and after, defeating the purpose of your extra work.

Anyone else feel this will help by removing the gas system from the equation?

Nope. But it's your rifle - dance a jig and sacrifice a pig before every shot if you want. I just don't think those will help any either.

If you decide to, let us know what differences it made.

Screwing around with a good reliable rifles gas block is some seriously bad mojo.

I've had a few frustrating gas block problems. Now I only run pinned gas blocks that can't move or loosen. If your gas block is working well and solid I wouldn't dare mess with it.

this makes sense to me. Zero is saying my cancelation of the gas system will alter the results, therefore diminishing the idea of load developement.
Those implying I'm permanently turning the rifle into a single shot have misread my meaning

 

[GRIZ22]

I see no sense in temporarily turning your SA into a single shot. You need to develop your load under the conditions it will be used.

OK bad idea, I'm convinced, thanks for your input
