Default CMMG Echo conversion kit grouping?

What kind of grouping out of my mid length 1/7 twist PSA upper with this kit installed should I expect? I know the twist rate isn't ideal but I'm shooting it and just wondering what other people are getting. Wondering if my grouping is normal or what. Basically I'm trying to figure out how much is the gun and how much is me. Lol

I had one that I put into my M400 1/7 twist, and I got about 5 MOA accuracy. BUT I wan't shooting fr accuracy and I am poor-average with iron sights, so you could reasonably expect 2 MOA.

Most dedicated 22 LR barrels have a 12 -16 rate of twist. A 7 rate of twist in a 223 would be for heavy bullets.

I've been looking at these also. Can't justify buying one until I can find ammo to use with it.

I was able to out shoot my conversion kit. It did about 4 MOA. Get a dedicated upper. Buy once. Cry once.
