Assume MSPR & AXMC/AXSR 300NM 26” prefit
Carbon Proof Barrel
Cost: $1,199.00
Weight: 3.937lbs
Cost/lb = $304.55
SS Proof Barrel
Cost: $709.00
Weight: 4.75lbs
Cost/lb = $149.26
Difference in weight is 0.813lbs
I just don’t see a good return on investment going to carbon. If it’s a hunting rifle that sees like 10 shots a year then it’ll last a life time and you’ll have < lb of savings so maybe that matters if you’re a mountain hunter. But I’d rather chop 4” off the barrel and call it good.

Attending the Polk high game this weekend. Number 33 is the guy to watch. Going to be better than the superbowl.
My 11” Carbon Bartlein 308w takes a pounding at the range. Lots of long strings. Mirage is apparent much faster than like for like non-CR barrels. Even still, dial back the magnification and it corrects the problem.
My ASR will be getting the Bruce Jenner cut shortly, too. Another shorty 308.
When that barrel is toast it would be interesting to cut in half. My gut says the inside layers of carbon will be completely delaminated but if it's stacking wtf cares.
Most of the highest temp rated resins I'm aware of start to reach tg around 600 f.
I just switched from a steel 20" M40 contour to a 24" CF straight 1.250 contour and saved around 2lbs. To me, there is hardly any weight difference going from a Proof Sendero contour to a straight contour. I'm more inclined to go for more straight contour Proofs as it looks mean as hell on the rifle.
Someone on the Hide was selling one about a year back on the Hide. I really need to go ahead and put in a order for a 30 cal straight contour for a upcoming build.
Part of the disparity in my comparison is that Proof has a weird contour for their SS AXMC/AXSR Prefits that is pretty light out the gate so it makes it look like the cost & weight saving between the two is almost meaningless.
I was in the carbon kick a few years ago considering I was getting 50% off Proof. Today I careless. Bergara has an interesting carbon/SS concept coming though
I tried running a carbon barrel with PRS style course of fire and it didn’t perform well at all. I don’t readily remember how bad it was but it was enough for me to say never again.
But if it works for other then so be it.
I’m curious how Bartlein carbon barrels are. I believe they make the steel sleeve thicker but I’m not sure.

I have had a few Proof CF barrels. They all have shot great but the one I chambered in 338 LM AI showed severe fire cracking long before my heavy Bartlein. My best guess is due to more barrel whip? I am not a engineer, hopefully someone much smarter can chime in 
The longest string I have had was 60 rounds in 45 minutes. Maybe 30 minutes. Been a few months. Either way, no idea what temp that is.
Unique to SBRs running suppressors.. the can gets insanely hot without much effort. Not sure it’s avoidable with majority of powders not designed to be burnt in such a short tube. A good can cover does a great job mitigating mirage.
Downside to Carbon.. seems to insulate heat longer than a traditional non-CF barrel.
No doubt. This was a bit of an experiment for me. Idea being it could be yanked out of a chassis an thrown into a hunting stock.
I haven't weighed this system, but it's most definitely not light. I'd say 14-15lbs with S&B, AXSR chassis, Raptar, TBAC and bipod. The carbon barrel probably didn't drop it a half lb, but Frank Green was upfront and entertained my shenanigans anyways.
It's a handy system tho. Repeating my results with the ASR.

I would like some advice.... New to the AI game - Picked up a AIAX SA / Sage green from the PX
Is there a parts schematic or reference I can find somewhere? Looked but came up empty. Im considering replacing a couple of small items and it would be very handy. Thoughts?
Thank you

Well…..short of trying to find my old paper manual that came with the rifle I’m not sure if there is one online somewhere. However your two main vendors for AI’s are going to be MileHigh and EuroOptoc. You can search their sites for “accessories” and find a lot of the stuff like but pads, rails, barrels, triggers, and various other small parts.

They don't have a full-blown schematic, but you can probably find what you need there.

Your best bet is generally to call Mile High Shooting, or email AINA directly with specific parts requests. They will help you out, get part numbers, etc, but you can only really get replacement parts from Mile High (unless it's a warranty issue direct through AINA).

Apparently AWSMs are going for $10k now lololol
Ok here it is. AX mark 3. Have been waited for this baby for a year and a half……
Sure thing sir. Will take more pictures today.
I don’t believe you that it is that slick. Send it to me so I know for sure. Lol
Nice! Do you have an AXSR bolt you can put it side by side with? From what I hear the AXSR is slicker/easier to cock than the AXSA/AT...so i'd be interested to see what they changed to improve it again.
Thanks!
While it has many similar features , I believe it is a separate model....and he just compared the feel to an axsr....
More to come.....
The gold and elite sand (put some respek on it) look sick together

This is AX Mark3 not AXSR. Very similar but not the same
@tomirwin or @Scott Seigmund , can you weigh in ? Is it just the AXSR action in a different chassis, or have there been tweaks to the action too?
Thanks
From the information that I gathered, mk3 has different bolt than AXSR… they are not interchangeable.
