I've only fired three groups with factory ammo in my Vanguard, but none of them (two 3-shot and one 5-shot) went over 7/8". That was with Fiocchi Extrema 40gr Vmax. I tried to work up a deer load with Nosler 64gr BSBs, only to discover that I had an early production S2 with a 1-14 twist. The bullets landed point-on, but the smallest groups were about
1 1/2" or so. No biggie, and my fault for lack of due diligence.
Newer ones are 1-9, good enough for up to 65gr or so.
The rifle has no issues with fit or function, apparently not the case for a lot of rifles these days.
Some (Boxer/Stick?) have said that some of the RARs have long 5.56 chambers, but short magazines that can give trouble accuracy-wise. Not sure about the details, but it's something to look into before you buy. Research is half the fun.
