Yes the rifle came with the Boyds Tacticool stock which I modified like 3 days in. Sanding out the barrel channel and bedding the action made a difference from the OEM stock. The Mcree G10 is what I shoot on all of my rifles so between the improved inlet, more rigidity and comfort behind the rifle... being identical in every way I did shoot more accurately yesterday. Makes sense since consistency is accuracy!
The other thing that is really nice running a G10 on a 16" barrel is that the weight is so well balanced. I use my 22 trainer for positional shooting and was damn accurate in various positions.
Lastly the Mag Well on the G10 for the CZ is awesome. I run a DIP extended lever and between that and the relief cuts, you can get a great purchase on the mags for changes. I show that in the 2nd pic above. Other 22 chassis leave the AICS mag cut out and you have to give the rifle a reach around to swap mags. This is very clean!
