I just installed a Clark Custom barrel in my 52-1. It is oversize in all the critical areas, including the muzzle ring, which is 0.005" oversized and needed trimming to fit the factory bushing. Both external and bore finish are very clean. My sample had a Rockwell C hardness measuring 40, which is right in the middle of the usual hardness spec for 416R barrels.
While they do have a bushing, I opted to fit the barrel to the factory bushing.

I believe the 52-1 has a slightly longer hood length than the -2 as my factory barrel measured 1.280" from the radial lug edge to the end of the hood, while my 52-2 top end measures 1.272". The Clark barrel measures 1.275" so you might want to check that dimension if you have a 52-1. I spoke to Jess Clark about what I found, and he said they will adjust their drawings to allow for the 52-1 dimensional difference. They designed their barrel around the 52-2 samples they had available and were not aware for the hood length differences.

My Ransom rest grip inserts arrived yesterday, so hopefully I will be able to test accuracy in the 52-1 at 25 yards (the only range I have access to at the moment is an indoor range, and that is as far as I can run a target).
I will post some results next week hopefully.
