Sionics - Upper received fit

[Torquetard]

Good company, I emailed them about an order and they tried calling me back. Missed the call but they tried. Anyway, I swapped rails on a Sionics upper and it had the same POI after reinstalling the barrel (it was snug but not gucci aerospace tolerances).

Heres a 100 yd sample from their medium profile. 62gr 223 hornady black, I believe they use 5.56 chambers on their barrels though

Thanks Torque (or do you prefer to go by “tard?”).
That’s really what I was looking for. Looking for something that is on the lower (tighter) side of tolerances.
I certainly believe all the good feedback on Sionics in general. I’ll be getting the NP3 BCG and all small parts there. Just looking to build out the rifle for the highest precision-type work possible, so it’s worth my asking about something as inane as the receiver fit, as BCM seems to be particularly tight.
