Bighorn Origin LA, SA question

[Ranger188]

If I have a shouldered barrel thats on my SA Origin,
will it fit a LA Origin will no problems?
Do they have the same head space and threads?

I believe they both have the same tenon length, and should headspace out the same.

Yeah, I think all of bighorns are that same tenon spec except for the tl3 due to the aw mag cut option that makes it .1 shorter or something but I wasnt 100% sure.

Origin short action, Origin long action and TL3/SR3 long action barrel tenons are all the same. The TL3/SR3 short action is the only different tenon.

Using a TL3/SR3 long action barrel on an Origin action is totally safe, but the engraving (if a pre-fit) will be 180* off as the thread start is at 12 o'clock on Origin's vs 6 o'clock on TL3/SR3's.
