For combat purposes the M7 and M250 are firing high velocity high pressure penetration type ammunition. That’s not match grade. 3-4MOA is the accepted accuracy of a service rifle. With match grade reduced velocity reduced pressure more specialized tips you can get better dispersion.

From what I know, unmodified qbz191 reliably shoots with errors under 2 MOA with the most common service rounds. It also have smaller recoil than other common assault rifles and have a whopping 30000 shot barrel life. Putting in effort can improve a grunt rifle, but cranking in ridiculous chamber pressures is probably the wrong way to go.

Chamber pressures vary based on caliber and how the cartridge is designed.
Also Press (F) to doubt.
2 MOA with accurate ammunition and a good shooter is possible. But that’s not using combat ammunition. 20,000+ rounds is realistic for an intermediate caliber rifle. The only way to pull off both those claims is if the data is manipulated.
4 MOA isn’t an outlier it’s what you expect from a combat weapon.

Well, obviously not both at the same time, accuracy wears out much faster than reliability. 2 MOA with combat ammunition is already achieved with a new rifle.

And despite the repeated meme. some early reports on M7 were in between 1-2.8 MOA range. 3-4 MOA is the accepted standard minimum. Sig and the Army both stated at least a 10000 round barrel life with some even going to 20,000. However that’s either generic situation reports or early unverified accounts.

The M7’s step away from the established norms is such that any report is taken and repeated. Even if said report is coming from left field or unverified. Glowing or otherwise everything should be taken with a grain or salt.
Farther the M7 program may be changing again as Sig is now floating a generation 2 version based on soldier feed back the M7 Product Improvement Effort. A pound lighter, improved barrel, non folding stock, improved suppressor, modified handguard. With option of going from 13” to 10” barrels. This isn’t uncommon for new weapons systems procurement. Once the soldiers get ahold of them a feed back loop of constructive criticism will be fed into it. One of the obvious issues was the weight. The new 13 inch version weighs lighter than the Scar H, just lighter than the AK12. Well the carbine version weight is identical to the Scar L.
