If one opts for a complete rifle from Volquartsen, the accuracy potential is likely much higher than a factory 10/22 Carbine. However, it is not much different than a DIY rifle. The differences is in acquisition cost. The Volquartsen rifle, while expensive, is less expensive than modifying a factory 10/22 unless one gets lucky. I have been lucky once and unlucky many other times. Many of the differences are in the tight-chambered Volquartsen barrel being threaded into the receiver and the TG2000 trigger group. A Kidd trigger group feels nicer to the trigger finger, but my experience with the TG2000 and Kidd trigger groups on the same rifle showed the less expensive TG2000 was not disadvantaged.
My most accurate rimfire is a Winchester 52D with a Leupold M8-12X on it. It sometimes shoots groups under 0.2" at 50 yards with certain lots of Lapua ammo from a Randolph rest. Switching to a different lot of the same Lapua ammo results in groups more than triple the size. It is extremely ammo picky and I dread having to find another lot it "likes" as that means a lot of trial and error. It will shoot eight rounds into a small group while the other two rounds more than double the group size. The groups also are also weather dependent with smaller groups on hotter, humid days. It will do 0.5" groups with many loads and fail to do better with most.
My "lucky" most accurate 10/22 is a factory 10/22 VLEHP model with the factory trigger group having a Kidd kit added to it and a McMillian stock from a Volquartsen rifle to aid in shooting from the rest. The VLEHP came with a factory 0.920" diameter 16.25" cold hammer forged barrel in a pink Hogue polymer stock. It cost me less than one quarter of any of my Volquartsen rifles as I got it from CDNN on clearance and outshoots all of them. The stock more than doubled the investment the rifle. It has shot 0.3" groups with certain lots of Gemtech Suppressor ammo and hates the Lapua ammo the 52D loves. I can usually shoot 0.5" groups at fifty yards unless the wind is wild or I fail to do my part. It is purely a bench rifle now. For going afield, I much prefer a Tactical Solutions rifle with the sleeved barrel and a Kidd trigger kit wearing a Leupold M8-8X as it is much easier to carry and shoot offhand.
Hard to beat this for an accurate field 10/22. https://volquartsen.com/inventory_co...75?clearance=1 or https://volquartsen.com/inventory_co...34?clearance=1
