Modern Sporter - Build Discussions

ANY pencil thin barrel will deflect from heat faster than a heavier barrel will. The Proof or BSF barrels have the advantage of using the carbon fiber to stiffen the thin profile barrel down so it does not deflect with heat. The downside is the cost.
If you are planning to run big mags and blast away all day a pencil barrel will not provide the accuracy, but then again what sort of accuarcy are you requiring. Some guys use volume of shots as a replacement for precise placement of shots. It is known as spray and pray.

The MRA barrel I have been shooting has proven to shoot well and is a good value. The Proof barrels on my MH and MV shoot very well and are close to the same weight as a light profile barrel, but cost is considerably higher.

Thanks! I don't think I'll be shooting a lot in a session anyways, maybe at most 100 rounds or so and definitely not in quick succession but maybe CF helps with longevity? Do you think it's worth the extra $500?

Proof claims that their CFW barrels last longer as they cool better but I truly believe this is marketing hype. The stainless steel barrel liner is still subject to the exact same instant heat and flame from the burning powder. I went CFW barrels stricly for the look cool factor, but they do shoot extremely well which is a bonus. Do they shoot any better than a conventional match grade barrel? Not in my experience.
 
Still looking for the price per .oz post

Im a cheap bastard and buy everything on sale :) or factory 2nds. The only parts here that I didnt get a deal on is the upper and lower. Heck that geissele has seen over 5k rounds thru my ACR...lol

My price per oz is probbaly pretty low. But im still not gonna look into it.

Deciding between barrels and can't choose. It's going to be for a multipurpose rifle for target shooting, hunting and maybe some competition. Is a MRA pencil barrel good enough or go for a CF wrapped barrel like BSF? Looked into Proof but too expensive.

If your doing any type of bench shooting, small groups , load development,etc, then the pencil barrel will suck.
After three rnds :)
I’ve read of a couple of issues with the BSF carbon wrap, separating from the steel.Not sure if it was a one off or not, but enough for me to steer clear.

I got a Christensen arms CFW ( am I allowed to say that?)
I’ve had a couple of proof CFW and a couple of CA CFW and both performed equally.

But if I couldn’t have a CFW I’d go with a maximum profile.
My gun should weigh just under 8 lbs.

Any gun that can’t shoot sub MOA is useless , to me.
 
I hope you’re better at building guns than math. ��

You’re at 6.6lbs ( 3KG x 2.2 ) without an upper.

Looks like a good build though, just poking fun where I can.

Under 7lbs shouldn't be an issue. Im at 5.1lbs (3kg) without upper.

Something being worth an extra $500 is pretty subjective. I would look at one of the fluted barrels to bring down weight if it is that big of a concern. Just dont go with a bull barrel and I am sure you will be fine.

Lug around a large frame semi and anything on the sporter build will feel light.
 
Talk to them yesterday. The uppers will be a bit yet. I was told end of the month mid February before we see them. 3 out of 4 mills broke down and set them back big time. Everything that happened before xmas was covered in the email blast sent out on the 27th.
 
Anyone know when then next preorders are up? I'm losing my will to resist these...

We're monitoring them on a day to day basis to see where we want to cut the preorder off. We already had to extend the numbers once due to the website accepting a large surplus of orders over one weekend, so now we're keeping a bit closer of an eye on it and trying to come up with an exact answer to this very question.


Were 1 week into January. Any updates on on uppers?
As was mentioned, we had a number of machines break down and require significant repair. I'm getting good reports that the machines we're running op 3 in should be back up and progressing very soon, but it's not an exact science, you fix one thing and discover another. We absolutely missed our goal to have uppers out for the end of 2018. As Greg mentioned, we are trying our hardest to get some out to anodizing ASAP and realistically i think that looks like the end of January (ie, 31st) or first half of February for the first parts.


The AT website is still accepting pre-orders.
And as long as the website says 2nd production run, that's what it will be. We'll update it before we switch over to taking orders for a third run.
 
In no way is this a dig, but could you just update the website more often? example: it still shows everything on track, with outdated dates, etc

I have it bookmarked to check up on it like probably many other, but its understandable if its not realistic to be modifying your site all the time, just a suggestion. Thanks

We have been putting absolutely all of our efforts into getting the mills back into operation and getting uppers machined. As a result some of our other normal day to day stuff has been neglected such as website maintenance. This has been addressed now. Soon we may actually get a chance to clean the floors, bathrooms and other housekeeping chores that have also been neglected.:cool:
 
Maybe some of the members here who keep asking when the uppers will be ready could come and do janitorial service in order to keep the production going.

dibs out from my end, it's a 4 hr drive to get there.....



I don't think asking for updates is too much to ask. I guarantee I'm busier than these people and work more hours. So why the sass?

The more they put into anything but machining means the less machining they can do (pretty obvious). I could care less how much you work, but I want ATRS working on building my receivers not answering everyone’s questions, since that means I have my receivers at an earlier date. They have the update before your post too btw, did you read all the posts? Do you want a hand written letter from Rick? I have hundreds of questions I could have asked Shaun or Rick but I shut up for the greater good.

Sorry for the rant but I’m tired of the whining, unfortunately your post was the one I quoted.

Whether they're working 6 hour days or 16, every minute they spend on a phone or in front of a computer responding to customers is a minute they don't spend working on the product. I'd rather they only focused on essential updates on the process and timelines than making regular ones that may or may not be of any meaningful substance.

What part of we will call you when it's ready and we expect our second run to be done August 2019 did your not understand???
 
So ATRS....do you need help? What can WE do to help you, aside from crowd funding some new mills? Would it help to have someone pack box's, inventory, stuff like that?

Thanks! I appreciate the response. I'm not in a rush; I just wanted an idea of what timeline to expect if I were to place an order today vs when I'd have the product in my hands.

I'm just a quick trip (500km) down the road from them. I volunteer my time to show up with a case of beer to clap and cheer loudly for them from the corner of the shop of your choosing while they work.
