Okay, my Google fu is weak. I will admit this. I just want a 510mm barrel, with a VSR-10 cut, in 6.01-6.03mm ID. PDI makes them in 430mm length, but the particular project I'm building (TSD SD700 base) means I need a 510mm barrel.
With the one local party I know out of the business, and EdGI basically unresponsive, I've come to you AP: where does a guy get a custom barrel cut these days?
