Has anyone made a bolt stop to allow users to shoot .308 or 6.5CM without the long action throw? I know the DT has ones for their system to take them from a long action to a short action. Thinking it would be easy to 3D print something to place in the rearmost sleeve to achieve this.

The "New" Barrett MRAD Thread!!!!!!

Honestly, I have never noticed, I don't use it in my DT so maybe muscle memory, run it and run it hard!
I’m so close to just listing up the AT and saying screw it, and giving the MRAD a try. I’m kinda AXSR shy at the moment, mainly due to cost, but also the trigger failing in the ASR trials (this gives me hesitation). Also, not digging their keylsot handguard, I much prefer MLOK. 
The only barrel I can seem to find right now is the Carbon fiber .300 PRC from Euro. Looks like I’d be starting out with a 22” .308 MRAD. Would then be searching for a 300PRC/Norma barrel most likely right away as well.

Where are you located and Barrett has barrels in stock. Gunbroker too. If you're close to CA you can play with mine...I’m so close to just listing up the AT and saying screw it, and giving the MRAD a try.

Man I wish, haha! Thank you tho. I’m about 2hrs 45mins from Barrett, lol!Where are you located and Barrett has barrels in stock. Gunbroker too. If you're close to CA you can play with mine...
So Barrett direct has barrels in stock? I didn’t find anything on gunbroker besides that 300PRC carbon barrel… me search fu must be weak.
Dang… never even considered that was a possibility. I need to do this asap. Hell, I wonder if they will just go ahead and sell me a rifle directly too?
I have no experience with the AI so take these comments with that in mind. I like the fact the MRAD is designed for the military so it is basically idiot proof. The plastic sleeve that seals the bolt area is a godsend in the desert. Super easy to service and with the upgraded bolt removal lever, barrel changes are a breeze. And the rifle is built in such a way you would have to really try hard to put it back together wrong. Everything is easily removable and serviceable.
As far as barrel kits go, unfortunately, Barrett is buried in military contracts. I would call them and ask about parts availability. They showed the 338 makers kit in stock so I ordered, but then after 2 months they said all barrel interfaces were going to military contracts. I contacted them and reminded them the kit had showed in stock when I purchased, and they made things right and shipped immediately. My first 300PRC kit is perfect. Southern Precision can usually get Bartlein barrels faster than most dealers and he has now done a bunch of maker's kits. Depending on barrel, they run about $1700 to $2000 but you can usually get in 2 to 3 months. I would highly encourage going with the Bartlein Mod BB. At shot show, Chase Stroud told me he attended some testing of the modBB. He had to leave before testing was complete, but said they were getting 30 to 35% more barrel life. When you are spending $1800 on the machined barrel with MRAD interface, to me the added cost of the upgrade is well worth it.

For what it's worth I actually emailed Barrett last night around the availability of a 6.5CM barrel kit. I was informed they put a temporary hold on the sale of barrel kits to the civilian market due to military order priority. Civilian sales will hopefully resume when the military requirements are met.
This alone might make me reconsider buying an MRAD right now unless you can find one in your desired caliber. Glad I ordered my kit when I did!! Southern Precision (bugholes.com) isn't far from Barrett in Tennessee. I wonder if he could get any makers kits direct from Barrett. Might be worth an ask.
Also have to agree with the other poster, the MRAD is on the heavy side. If I didn't plan on shooting magnum calibers, I would probably pick another platform for anything less than 300 WM. I have a Daniel Defense 18" barrel AR that shoots factory 6.5 Creedmor sub moa and is less than 10lbs with a Trijicon Scope.
A's are for .338 Lapua D's are 300 Norma. Followers look the same. only difference on the mag is a seam under the mag catch on the rear of the mag.
Thanks. Picked up the 300 norma kit and the bolt and barrel are stamped A but came with D magazine.
No, that's the internal thread that mates with the barrel... he's asking for the external thread where the suppressor mounts onto.
The thread for their 30cal one is: 1" 1/16-18 thread pitch
And then the 338 one is: 1" 1/4-18 thread pitch
Found on their Webstore looking up thread protectors
Looking for a suppressor for the Mrad will the AM338 screw on to the lower calibers or do i need to get the AM30 for those
Yes/No. Barrett sells two different 30 cal muzzle brakes one for the AM30 and one for the AM338. Not sure which one ships on the 30 Cal Mrads or the conversion kits. I swapped all mine out for Rearden Devices, so I can run any of my Dead Air/Silencerco/Form 1 cans.
Barrett just got back to me the AM338 fits all barrels except the 308 and 6.5 those just need a AM338 muzzle brake with 5/8x24 threads
So earlier I asked about options for a case for an MRAD with a wide-bipod, big scope and... interesting grip. Turned out I had the solution around all the time.
Back about 15 years ago, I bought a couple of Stinger Cases when they were easy to get and cheap from Sportsmans Guide or something like that. I used them to transport crankshafts to and from grinding. But they got to be too bulky and unwieldy.
So... with some measuring, these are perfect not only to fit an MRAD, but a spare barrel, suppressor, magazines, ammo, tripod spotting scope...
First step (and all I have accomplished so far) is to remove the foam from the case. And holy hell on a ham hock... is that a job! It's massively strong foam (and some styrofoam) held in with, I guess, some kind of hot glue. Put together by people who were, apparently, paid by the gallon of glue that they used. Getting the foam out of one of these is a battle! I heard that these were sold to the gummint from the late '70s into the 1990's for $2300 a case. And I think most of that was glue.
Using a Geisswein vibrating saw, and 3 hours, I finally got the foam out. But there is still a bunch of glue and 'scraps' of foam that I can remove with an angle grinder and a sanding disk. But I started to do that inside and think I unleashed a toxic cloud that will have Al Gore writing me a nasty letter. So until I can do it outside... I'm going to hold off on the rest of the removal. Then I'll paint the inside again with CARC.
I have foam on order. For those big boys, an old surplus Stinger Case is going to be just the thing! More to follow!

Just got an email from Bugholes.com. My 33XC MRAD Barrel should be here the end of next week. I didn't have time for him to keep it for another week or two to Cerakote it, but I will do that when I get back from my ELR class with Chase. Hopefully the paint doesn't change the POI too much... haha.
Hey y'all, what are your thoughts on suppressors for magnum or extreme ELR calibers? Most of the ELR guns I see have some type of huge muzzle brake. I'm inclined to think in the heavier calibers the brakes are much more effective at recoil reduction than a can, but have no info to support that. I did call Barrett and they advised that my AM338 would be fine running the XC, i.e., 500 fps faster than standard Lapua. But thinking of future builds, I'm thinking anything above 338 would get a big brake. Thoughts??
Personally I love my Surefire can on my 300wm and 338lm. Just range time and field use. MRAD shoots fine all day, <50 rounds, with a Surefire brake; but is a pleasure with a suppressor.
So I recently picked up a 6.5CM barrel for my MRAD however I ran into a snag last night when I tried to shoot the barrel...... Turns out the bolt for the 6.5 is not compatible with the bolt housing assembly for my rifle. The issue is the 6.5 bolt does not have a "notch" on the top side that my 338LM and 300PRC bolts have.
Am I missing something here around why this 6.5 bolt won't work with my bolt housing?
Pictures for reference. The bolt that works is the one with the "notch" cut, the 6.5 bolt does not have this notch.

.338 and under suppress it, .375 and over muzzlebrake. I had a .375 allen mag(cheytac improved) built on a single shot action(19lb gun) with 32 inch barrel launching 350 smk's at 3250 with 140 grains or so of re33 and suppressed recoil wasn't pleasant.

The notch was a revision to "poka yoke" the bolt. I.e., you cannot put the bolt in the tube the wrong way.
Your 6.5 bolt should have a step in the cross-pin hole also.
Call Customer service and they will get you squared away.

I do not own a MRAD and only held one a long time ago, but this is what I think is going on (pure speculation).
The bottom bolt head (6.5CM) was an earlier model where the bolt cross pin was able to be removed from the bolt body assembly. The cross pin was stepped to ensure that the user can only install the bolt head the correct way around.
Later models of the MRAD seems to have the cross pin permanently retained to the bolt body. My guess it was a requirement for a later government contract. In order for this to work, they had to cut the big notch you see in your 300PRC/338LM.
Your best option is to reach out to the people that supplied you the 6.5CM bolt head as there don't seem to be an easy fix for your problem.
Hope they can help you out and thus get you on the range to enjoy that rifle!

Bartlein 33XC Mod BB has arrived!!! Thanks again to Southern Precision for another superb Maker's kit!
Headed to Austin Easter weekend for a wind class with Chase Stroud so report coming soon.
Right now all the barrel makers kits are sold out and production is focused on Mk22 contracts. The kits are pretty much defined by lapua bolt face, magnum bolt face, .308 bolt face. What kind of 30 cal build you looking to do?
Thanks. I was wanting to do a .308 Win build, 26" barrel. Contacted Southern Precision, but without the builders kit it is a no go.
I ordered a Barrett suppressor... made for the gun and the caliber(s). .338. Spins right on the factory brake.
Looked at a bunch of options, but for the price decided that Barrett engineers knew what they were doing when they created the platform and they probably knew what they were doing when they built the brake and suppressor. So I'm not going to second guess them.
That said, I am sure there are some good 'other' options out there and am also interested in other folks' thoughts!
Cheers,

Chase Stroud's one-on-one training was worth every dime. The first day was a beginner's intro into reloading and load development, since I have never reloaded. Chase was EXTREMELY knowledgeable and supplies video's to his clients so they can go back and refer to them. I was not interested in ringing out every last fps but wanted decent velocity with good barrel life. We wound up with 120.4 grains of H50BMG for the Badlands 275gr Super Bulldozer-2 at 3180 fps with ES of 8 after fire forming. When Chase was done, this barrel was putting 5 bullets through the same hole at 100 yards and shooting a 1-inch group at 500 yds. Even Chase, an ELR World Record holder, was astonished at the accuracy. Since his reloading equipment was 15 feet from his range, me trying to duplicate this where I live would have taken me countless hours learning online and numerous trips to the range.
The next day, with Chase spotting, I was able to make two consecutive hits at 2-miles in 13-22 mph winds. When I was leaving, Chase told me my MRAD could easily compete in the King of 2 Miles (to clarify-the gun not me ). To say I was ecstatic with the whole experience is the understatement of the year!!! If you are interested in taking your ELR skill set to the next level, or the first level in my case, I would highly recommend training with Chase. He's an hour or so outside Austin and easy to get to. I've always believed the best person to learn from is the one who is doing the skill you wish to aquire and doing it extremely well.
Also, big shout out to Greg and Russ of Southern Precision (bugholes.com) for turning out such an amazing Maker's Kit-Bartlein combo. The Bartlein mod BB seems to be the ticket!! Chase scoped the barrel after 50 or so rounds and there was ZERO firecracking. The 1 in 8 twist loved the Badlands 275s!

Thanks for the report swatdude. Sounds like a real winner. Keep us updated on that cartridge. Really interesting. Btw, I think brian litz won the elr match with an mrad in 300nm in Casper last summer. The platform really seems to have been refined. I just wish I had gotten a couple maker kits at Christmas when I had the chance.
Seriously kicking myself as well for not grabbing a maker kit when I had the chance...

Looks like an awesome time! Sharp looking MRAD as well!
I left my rifle with Chase to work up a load for my 338NM barrel since we ran out of time. Debating whether or not to keep my Bartlein Maker's Kit in 300PRC. Not sure how much I want to be switching back and forth a lot between multiple calibers. I can see keeping 300PRC if the cost per round is significantly less than 338NM. Anyone have a good feel for that? I bought Hornady A-tips for the 338NM so I can mag load that round. The 275 badlands SB-2 OAL was too long.

Is the mount a 0 or 20 moa version of the NF ultramount on the mk22 deployment kits? Looking to get my order placed today if anyone can chime in and help.
