+1 ZRTS

[YugoGo]

I bought an Sig 516 upper and didn't do my due diligence. When I got it, something seemed off about the threading. I took it over to them to give it a once over and I was correct in my suspicions. they cut off the fugly non-concentric thread and had it turned around back to mein less than 4 hours. Truly first class service.
