Seekins ph3

Just watched the guns America YouTube. Looks interesting. Like the quick change barrels, although ths pinned collar seems like it might lend itself to play, and the supposed lightened bolt lift. It'll be interesting to see some start trickling out.
Not sure how they lightened the bolt lift going from a 90° to a 60° since that will give less of a mechanical advantage and you're trying to cock that firing pin the same amount with less ramp to do it. That said, I've never had a problem with any of my 90° bolts, Havak Hit included.
 
I was told by Seekins that old hit barrels work in the new hit rifle but not the other way around. New barrels won’t work on the old action.
I'm struggling to understand how this would work....all a barrel/action interface is is threads and headspace, which either work or they don't. How can it work for one but not the other?

AI AW/AX barrels will work on an AE but AE barrels won’t work on them. True AE barrels aren’t threaded under the lug. If the statement is accurate (I have no clue) I’d say something similar changed in those regards since the clamping paw is now inside the action instead of in front of the action on the rail. It could be just like the AI AE’s where the old ones weren’t threaded all the way to the shoulder and now they are. There could be a relief in the new tenons where they’ll still work in the old actions but the old barrels won’t work in the new. There’s plenty of ways they could be backwards compatible and it’s not as simple as a thread is a thread. It could also be the bolt nose recess and not be the threads at all.

Wouldn't the bolt nose recess affect headspacing and therefor only work one way? I'm curious from an engineering perspective to know how this all works.

what I’ve seen is the the new rifles support more of the case head. The new barrel tenon is slightly longer and would interfere with the bolt head of the old rifles

Send my PH2 Seekins Stock back in for an Mlok rail addition for an arca rail.
  1. Contacted them and they emailed a RMA w/ FedEx label that afternoon.
  2. Shipped same day
  3. 10 days later(including TWO weekends) back home, MLok installed.
I just cannot say enough about their customer service! Looking at getting a PH-3 from Scheels next.
