I wanted to share some findings I made today. Initially I had been using the EagleVision VCK-2 adapter from AoA on my 1/2UNF moderators. I saw Fransisco was selling the Eagle Vision VCB-2 and when Brian stocked them decided to try it out as it had a sleeker line covering the end of the barrel.
I had thought it was working just fine, but I had been switching between the VCK-2 and VCB-2 when I swapped barrels. I started to notice a week or so ago that I was not getting one-hole groups at my indoor 13 yard setup. I mostly shoot the Leshiy 2 off-hand so it's not something I'd pick up all the time, but I started shooting it from the bench yesterday afternoon and I couldn't for the life of me get a one-hole 8 shot group with the VCB-2 adapter.
Light-bulb moment back to when I was trying the 14mm DonnyFL adapter. I wonder if the end of the barrel is sitting flush with the inside of adapter.
Caliper time:
Internal depth of the VCB-2 = 1.12"
Installed the adapter tightly on a barrel and put a Sharpie mark.
Compare the two measurements and there's definitely ~1/4" of space between the barrel end and the adapter end.
I removed the VCB-2 and replaced it with the VCK-2 and back to single hole 8-shot mags.
