Muzzle diameter of 24.3" barrel on a Tikka T3x lite in 6.5 PRC

[North of 60]

Looking for the muzzle diameter of a 24.3" barrel on a Tikka T3x lite in 6.5 PRC. Can somebody mic it for me who has one? Thinking chromemoly or stainless should be close in diameter, if not identical.

Curious if it is .630" or larger for threading purposes with a eurooptic deal, or if i will just purchase one of the newer (more expensive) ones already threaded 5/8x24.

And yes, i want the the longer barrel for this particular rifle with a ZG 6.5 suppressor for the velocity.

TIA

I just had my Eurooptic roughtech superlite threaded 5/8"-24 with a shoulder added, and the barrel was around 0.64X" at the muzzle (D16.5 profile? I'll check and update). You just need a barrel diameter slightly above the major diameter of 5/8" thread which is 0.6239" as long as your gunsmith can add a shoulder. I think the thinnest tikka barrel profile is D16 (16mm) which is 0.629" diameter.

Thx much Andouille, was your superlite 24.3" in length?

And do we know if the superlites have thinner barrels than lites?

If the T3x lite in 6.5 PRC is .630 or better at the muzzle, it may be a little cheaper to have Karl Feldkamp in ID thread it for me than to get a new model already threaded.

Well, i assumed there's a few inches of constant diameter near the muzzle, but that's not the case.

my roughtech superlite was around 0.640 at 20", so im not sure if the taper is the same as a longer barrel. It's now 0.657 at 19" length (1/2" from flutes) so thats not helpful.

Plain stainless Lite and superlight non-roughtech are the same barrels, the latter having flutes. I just measured a 24.3" 300WM stainless lite and the very tip of the muzzle diameter is 0.618". Too thin for 5/8-24 without losing about 2.5-3" to get to thicker diameter, but you can absolutely go 1/2-28" with a nice 5/8-24" thread adapter permanently installed by a gunsmith.

If you're looking at a gun from Eurooptic, you can ask them what the barrel profile is (D18, D16.5, D16), i think they can tell from the codes on the box
