Which AR upper has precision guarantee?

[BAGunner]

FNAR Match has factory sub MOA guarantee. Is there any AR upper claiming similar precision from the factory/builder?

Thanks.

There are lots of companies that list the accuracy guarantee on their webpages. Keep in mind that the accuracy guarantees only apply to the use premium match grade ammo shot by people that can hold such tight groups (or in a rest).

The Stag varminter comes with a 1/4 MOA at 100 yards guarantee.

If memory serves, all of the Rock River uppers have a 1 MOA guarantee. Their varminter uppers have 1/2 MOA guarantees.

The guys lauded as making the "finest" uppers in the industry don't list accuracy guarantees. They don't have to list accuracy figures for their equipment to sell. Compass lake engineering, Krieger, and White Oak Armament are regarded by many well ranked competitive shooters as being the best in the business. Also, their prices on their uppers (or the cost to built one with their components) is not that much different from many factory varminter uppers. The big difference is the wait time to get one (like 6 months generally).
