ARC, Archimedes shoulder barrel prefit tennon is the same as?

Boatninja · Dec 28, 2024

I'm aware that ARC's are Savage Small Shank and will work on other SSS with a barrel nut.
I seem to remember one or more ARC shouldered barrel tenons were the same as one of the Impact actions.
Any intel on this? I could very well be mistaken.
Appreciate it!

Pretty sure none of the Impact prefits will fit any of the ARC actions. Impact is 16 TPI and ARC are 20 TPI.

If i recall you can use an Orgin barrel with a spacer that PVA used to make. Thats been a few years ago and i could be mistaken.

I believe the Archimedes has .020" less headspace than a TL3. I have a Bugnut SPR ARC barrel in a TL3 and it screws all the way down onto a G0 gage with about .005" of adjustable depth left. It should have a lot more if it were in an ARC action and it's only luck it fits in a TL3.

Yea, My mistake! Totally wrong action, it is Aero Solas action will fit a Zermatt Origin shouldered barrel.
I've looked at so many actions and barrels I'm getting cross-eyed, they are all running together.
