Bore diameter is 314. Barrel is on a original PU sniper. I want to put a Ex Pu sniper barrel on this
rifle and restore its accuracy.

As you know, PU sniper rifles never had .308 barrels , only a few Fin models had them.

However, considering the fact that a gunsmith has yet to be found that has the experience to do this
and only because of that, I have elected to take the ex PU sniper, re sniper it and shoot that restored
rifle. The old PU original sniper is retired.
