AQ planned for years and sent their A team to carry out the attacks, and on Flight 93 they were thwarted by a pick-up team made up of United Frequent Fliers. Many people look at 9/11 and wonder how we can stop an enemy like that. I look at FL93 and wonder, "How can we lose?". -- FromMyColdDeadHand
Regardless of what I intend to use a 5.56mm carbine for, I will test it with a magnified optic and good match quality ammo that is appropriate for the twist rate of the barrel.
OP if you have a magnified optic and want to see what the carbine can do, mount the scope and go find a box or two of match ammo and shoot some 10 shot groups or 5 shot groups if 10 shot groups are too much for you. Then you will know what the barrel is capable of if you ever need to press it into a different role.
My Colt, DD, and KAC will all hold right around .9-1.2 MOA at 100 yards with good match ammo for 10 shots if I can keep my concentration up long enough to shoot a clean 10 shot string. That’s with 15X Nightforce on top handling aiming duty. I don’t use that optic on any of the carbines for anything but testing because it’s huge and heavy, but it’s worth knowing if I’m getting trash results because of ammo, sights, or the barrel. I have yet to see a quality barrel running quality ammo fail to turn in nice groups with a decent magnified optic. So I don’t sweat it when I get 4 MOA groups out of the same gun when I’m running blaster practice ammo out of it with a red dot.
Here's my best group with a Centurion Arms 16" lightweight barrel at 100 yards with a 3-15x Vortex scope. This was PMC Bronze .223 55gr.
To the OP; a few comments:
1. M193 is not match grade ammunition. Even if other posters have 1 or 2 good groups to post; I'd be willing to bet they cant do that on command; like a mk262 load can.
2. Most people posting good groups are using magnified optics. The higher the magnification the easier it is to get a consistent POA.
3. Are you using a bipod or front/rear bags? They matter a lot.
4. Are you a good bench rest shooter? I was NOT when I started, but with practice am much more consistent now. Still not perfect, but more consistent.
