I bought the barrel assembly from Osage County Guns in MO. They sell a lot of Sig parts and one can buy a barrel with the extension on it for around $429.Where did you buy the new extension?

What is your dope for this loadFirst 3 rounds today...
I thought I would update my previous posts. I wish I had a little more info, but I'll share what I have. In previous posts, I discussed the extreme out of alignment of my bore and optic exampled in the problem that I couldn't zero all but one optic which was an Eotech Vudu 5-25 with an actual 25 mils of windage.
I purchased a Sig barrel assembly which allowed for the replacement of my barrel and extension. This solved the issue. I wish I would have utilized the new extension with the old barrel and tested to see if I could isolate the problem (I'm assuming thread mating on either or both), but I settled on using the new extension and new barrel. Head spacing the new barrel assembly to my bolt was too easy (Brownell's barrel vice, 50-250 lbs torque wrench, AR wrench, gauges, 1 1/16" Large Box Wrench). I would have liked to isolate the barrel or the extension as the culprit, but the new barrel is a shooter so not looking to tear it back apart.
I now have the Vortex LHT 4.5-22 mounted and my zero is almost at the center of my windage adjustment.
As to parts, I purchased the complete Sig 6.5CM barrel assembly which combined a new barrel. extension and jam nut. The Sig barrel assembly did not come with any muzzle adapters or thread protector.
I initially purchased the rifle at Bass Pro when they had an amazing sale on the 6.5 CM model. I think I paid around $1,300 before tax. After spending over $400 on the new barrel and extension, the original sale wasn't so....good. I will probably contact Sig to let them know about the fix as they sent it back to me and reported it as acceptable with no other data. In all fairness, CS was good, kind, but they failed to address the issues or provide what "acceptable" meant.
For those who have had similar problems pertaining to alignment, I suspect, you could check head spacing, maybe spin the barrel in the extension, moving your barrel in a "positive" direction...if headspace allows.
Again, not exact, I didn't isolate the issue, but it's fixed. For those who suspected the receiver face or picatinny rail...maybe, but mine was somewhere within the barrel/extension interface.
Lastly...I also picked up 60 fps with the new, same length barrel.
Blessings,
BC
I don't have calipers. I was hoping someone with a factory 6.5 barrel may have already measured and could provide some feedback. I'd appreciate it!Can you measure your barrel diameter right next to where the thread starts?
@BELLYCRAWL You mentioned in another thread that the new barrel did not have proper headspace when you installed it. This makes me wonder if the original barrel was actually off in some headspace-related tolerance? Sounds like it is water under the bridge for you, but it might explain the CS response and shooting performance of the original barrel.
A ruler to get an approximation?I don't have calipers. I was hoping someone with a factory 6.5 barrel may have already measured and could provide some feedback. I'd appreciate it!

1.00”Can you measure your barrel diameter right next to where the thread starts?
How much and how much does it weigh vs the original?Sig factory arca rail is legit…

I would think even something cheaper that wont require harding and can be soft turned and still hold up, like maybe 416RQ or even 17/40 but the design would work well or at least it should. i would be interested in purchasing these if you make them
Straight Jacket Armory, LLC
I decided to forgo the Sig Cross, due to lots of things I would change about them, and their hit-or-miss consistency, and landed on 2 Christensen Arms MPR rifles instead... Both 16", one in .308 Win, and the other in 6mm ARC. They are similar in design (feel) to the Sig Cross, which is similar to an AR platform, since the grip is a pistol grip, and the stock is setup in a straight line with the action, but after a few hundred shots I'm getting better with them. It's for sure a muscle-memory learning curve to shoot a chassis gun, but I have a feeling that with time, I'll be as comfortable as I am with a traditional stock'd rifle.Judging by how it looks, it seems like it would be similar to shooting an AR (fundamentally and feel). Which is a whole different ballgame compared to bolt-actions. Been shooting guns my whole life, but it took me a long time to get comfortable enough to shoot an AR with any real precision and consistency. And even after all these years of shooting them, it still feels weird when I jump from bolt to AR.
I would like one pleaseSince no one that I am aware of currently makes an aftermarket bag rider for this rifle. I decided to model up a prototype in solidworks and 3D print one. It bolted right up using the stock screws and worked flawless. Clearance for the screw heads was a bit tight with my printer but not bad. Might make a few small tweaks in the near future, but its made form standard PLA and is very light if thats a concern. Very sold with full infill in the print. If anyone would like the .STL file to print on their own I would be happy to send.

Eh. Most people don’t need a rail all the way down the handguard. And adding a 2 inch longer barrel doesn’t give that much more velocity. From what I see it looks like this model is about $200 more than the standard model. My 18 inch Creedmoor cross shoot under half inch groups very easily.
Yeah, not really sure why they added this along with the PRS. But I guess more choices are usually good.Eh. Most people don’t need a rail all the way down the handguard.

Beats me. If you can get over not having the arca rail that the PRS comes with, you can get a standard cross for $1500, and a custom prefit for $509, and probably have a better shooter than the PRS model for $500 lessYeah, not really sure why they added this along with the PRS.

I’d buy a 223 16-18” cross in a heart beatI still think they should have made a short barreled version in .223 for the European hunting market.
It would have to be Pin and Welded or it wouldn’t sell hereI would be happy with a 14.5" barrel, would be a fantastic light weight foxing rifle.
Count me in!I’d buy a 223 16-18” cross in a heart beat
Maybe, but the PRS has more than a longer barrel, like ARCA rail you mention, but also the heavier stock, different grip, better mag release, etcBeats me.

M16/M4/AR are not drop safe.
does .223 become a viable hunting round out of a short barrel once you get to Europe?I still think they should have made a short barreled version in .223 for the European hunting market.
In England .223 is used mainly for foxes and two small breeds of deer.does .223 become a viable hunting round out of a short barrel once you get to Europe?
that makes a lot of sense, especially at that range. curious, are foxes there a pest animal or do you hunt them for meat/pelt?In England .223 is used mainly for foxes and two small breeds of deer.
My short barreled .223 has accounted for a lot of foxes and deer with the farthest fox being 237y. Where I shoot, it is mainly small fields and rolling hills so a short barreled, light .223 is perfect for the job.
Foxes are a pest for farmers as they take lambs, piglets, chickens, etc. Same situation on game shoots with the birds.that makes a lot of sense, especially at that range. curious, are foxes there a pest animal or do you hunt them for meat/pelt?
also, that doesn't look like a short barrel in your photo, no? i know .223 loses a lot of velocity under 11/10".
Yes, I have one, but measuring this distance does not seem straight forward.Buy yourself a vernier caliper; easy to use and you can then also measure your scope height for Strelok Pro.
measure from where the ring halves meet to the bottom of the eject port on the action, which is about center of the barrel.Yes, I have one, but measuring this distance does not seem straight forward.
Do you have advice regarding the points to measure on the gun?
Thank you. Your advice gave me more insight and I tried a few ideas of my own in addition to yours. I came up with 1.2" from the barrel center (used the firing pin hole in the bolt) to the top of the picatinny rail. This was on the standard Cross, 308.measure from where the ring halves meet to the bottom of the eject port on the action, which is about center of the barrel.
Nice. Did you get a price?Sig customer service advised that the “integral base mount” pictured on page 91 of the manual has been assigned a part number, but is not yet available. Based on the recent availability of the 0 MOA picatinny mount, the rep guessed it will be available “soon”.
