Barrel Length & Scope Ring Selection

[edub1309]

Hi all. Putting together a 6.5 CM build on an AI AT Chassis. Defiance Deviant Tactical action with triggertech trigger/safety. Pairing it with a PROOF CF barrel, but I'm not sure if I should go 22" or 24", or if there is even a practical difference between the two?

For glass I'm going with the Vortex Razor Gen II on a SPUHR mount. I'm looking at the SP-4002 34mm that is 1.5" tall. Is that the right one? I imagine I'll have plenty of clearance, but want to make sure I'm not missing anything?

For anybody wondering the purpose/goals for this rifle: I'd like to consistently reach 750-1k yards, and push it out to 1,700 yards or so. I know that's a bit far, but that's the goal. I won't be hunting with this rifle.

You can absolutely shoot a 22” 6.5cm to a mile.

24” is said to be optimal for factory ammo.
If your not hunting or need a light rifle I’d skip the CF barrel.

If you not hunting and want to stretch it's legs, why give up the free velocity... Go 24”

1.5" on the mount may be a bit much. I'm using the same action and scope on my 6 and am using a 1.125" MPA mount. Plenty of room for scope caps.

Do you recommend the PROOF steel barrels? I read that the cf had longer life and the heat dissipation helped with accuracy.. is that just hogwash?

 

[edub1309]

That makes sense and was what I was thinking. I might hike with it, but 2” really won’t make that much of a difference. Thank you!

 

[edub1309]

I believe they do a 1.35 as well. I was going with 1.5 based on the MPA recommendation actually. How do you like that action?

 

[Rocketmandb]

Love it

 

[Steel head]

Absolutely!
Barrels life between the two will in no way offset the price difference.

Later this evening or tomorrow, I'll take a close up of my 6 and send it to you so you can see the height.

Thanks man! Glad to hear you love the action.. I’m looking forward to getting it in hand... 4-6 months from now ?

 

[edub1309]

Okay good to know. In that case I think I’ll go the steel route and have it cerakoted. Thank you!

Sounds like a fun build, yeah the 1.5" high mount is for a top full length pic rail, like a AR or MRAD,etc...prob jus use the Spuhr in 1.34" height imho.

This is my “keep forever” build; it’s been fun to start piecing parts together for it. Thank you for the info! Looks like the SP-4006 is the one I’m looking for. Thanks again!
