My 6mm ARC barrel from PF is a 6 groove Criterion...
Most of the star gauged barrels meant for M1903A4 sniper rifles in WWII were 4 groove barrels. Some of them just had 2 grooves & were very accurate. I suspect your 4 groove barrel will shoot just fine.

I refuse to be victimized by notions of virtuous behavior.
