Looks like a second Rokstok has hit the classifieds.
Iv had this issue with manners and McMillan.This one was 7.5 twist so they do do that. It’s not a full 1.2” shank it’s just a little above 1.115 or whatever tikka action faces are. The lite contour ace blank I got is a little bigger too, not quite as big as the pva though.
To be honest imho this is on PVA and not any given stock maker. PVA deviated from the Tikka shank diameter. If stock makers made this area oversized “just in case” a barrel maker exceeded the stock size from the manufacturer there would probably be more people bitching the stock is “sloppy”. Seems like either PVA needs to fall in line or someone ordering a PVA needs to realize they need to sand the stock for the out of spec barrel. The tail doesn’t wag the dog and this specific thing isn’t on stockys imho.PVA doesn't have a contour spec last I looked. Factory Tikka shank measures 1.125", the PVA 750 taperless measured 1.165"ish. This is just with calipers. I took the PVA barrel off and put my other one back on after seeing the contact and not having anything on hand to quickly open it up so dont have pictures. Not difficult to address at home but IMO stocky's should open up the channels in this location more.
This is the Tikka prefit correct? I think the standard Proof Sendero is like a 1.2 or something.

So is a 1.2 too big for a Tikka action?Yes. You are correct that the standard proof sendero contour is larger like most common contours. 1.2 and 1.25 is the majority of aftermarket blank contours.

Thanks for the info! I sent a Bartlein CF barrel to Unkown so they could build a 7PRC with a Tikka action. Waiting on a Rokstok at this point. My barrel has a 1.2 shank. I didn't realize that it's bigger in diameter than the Tikka action when I started this process. Do you know if this is something that could be machined down to match the action?Depends what is meant by "too big". A 1.2" shank could still function fine. Tikka actions have a chamfered face so a barrel tennon shoulder above 1.125" is larger than the dimension it shoulders to on the face of a tikka. It just results in a little ridge where the barrel shank is larger than the face of the action. Basically the only downsides are the aesthetics, a little extra weight, and possible contact with an inlet set for a factory Tikka shank.
I've had gunsmiths turn down the shank on other sporter blanks when chambering for a tikka and it has been a non-issue.
It seems the ACE tikka lite contour blanks are set at 1.13" and they have a very small ridge.
You'd have to ask UM but kind of doubt it because I think the carbon comes up to full shank diameter. Before the tikka prefit market took off it wasn't that uncommon to have the chamfer machined off to have a square 1.2" face on tikkas to more shoulder engagement/diameter. I have one tikka done up that way.Thanks for the info! I sent a Bartlein CF barrel to Unkown so they could build a 7PRC with a Tikka action. Waiting on a Rokstok at this point.

Yes to the ctr inlet and no the Howa mini is not an option on the current rokstok but will be in the lite model.
If you end up not liking it and want to sell it for what you put into it, please let me knowPlain carbon, no scallop, 3b tikka inlet delivered today, July 29th, 2024. First day order.
In looking it over and putting it on my rifle, the finish is fine.
It's definitely different. I'm still trying to decide if I like it after shooting about 40rds this afternoon.

Right!?Or you can list it and make $350...
