feedback on Seekins ph3 barrel swaps

[Beanz]

Looking at getting a 6mm creedmoor for hunting/plinking at distance and the PH3 seems to check all the boxes for the price point. Biggest concern is the aftermarket support, have the bolt heads and barrels started trickling in to stocking dealers? Another option would be a Proof Elevation MTR 2.0 in 6mm found one sub 2,700 so that may the better option with aftermarket support. Just looking for honest feedback and opinions.
