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

[Ehtacs]

What is that standard muzzle diameter of a the larger 30 cal magnum calibers like 300 norma on the standard, factory steel Barrett barrel?

My 26" 300WM and 26" 300NM are showing 0.9" OD at the shoulder. Threads should be 5/8-24.

ETA - Still need to snap some better pics but I finished shooting session #2 with the A419 Mk22 Arcalok rail. I'm a fan overall but the Arcalok adapter has been reassigned to Garmin Xero duty. Went to the ADM adapter and I'm much happier with it. @Swatdude1 I was just working through the skis thing myself! My Atlas CAL soft, super sticky rubber feet are already noticeably worn after only 122 rounds. My range doesn't have anything to really load the bipod into so recoil control really comes down to me. Just moving the rifle around the table has it jumping and bouncing on the soft sticky rubber feet... Skis rolled in earlier this week and I finally installed them today. I'll be curious if allowing the rifle slide smoothly back has any noticeable effect, besides more felt recoil.

Noticeable affect is better accuracy due to consistent rearward motion. It is easier to duplicate a light touch to the shoulder than pulling the gun in hard with your bicep. You will never be able to duplicate the amount of force you apply each time with a strong pull. Also, front loading a bipod with one that has ANY give at all will also introduce effects that keep the barrel from recoiling directly back in a straight line. Think about it... with the bipod legs pushed back hard, the height of the barrel is reduced. When fired, as the rife moves rearward, the barrel will actually increase in height as the bipod legs hit their full height through recoil. There is also the benefit of getting your sight picture back quickly to witness impacts.
The proof was in the pudding when this extreme newb to even bolt guns in general hit two consecutive shots at 2 miles in 13-20mph winds. And at that time I was using a crappy bipod without skis (not loading it though). Note: the weight of your rifle will have a big effect on how free recoiling feels to you. My MRAD all decked out with ATACR and AccuTac bipod weighs 27 lbs with the 33XC barrel and after shooting almost a hundred 33XC rounds that day with Chase, I had minimal shoulder discomfort.

Mike, get those bipods pushed out to the front of your ARCA rail.

 

[Sgtsideways]

Got to agree with Swat on the bipod location. It was one of the big mistakes I was making in lr shooting. I was always of the opinion that force on a bipod had to be forward directed and that you hold the rifle grip tightly. It kinda screws up the center of gravity with regards to recoil.
My groups didn't straighten out until I went with a adjustable bag rider, a straight rifle grip, and a good bag. Getting the trigger finger at 90 degrees, along with trigger control/follow thru was also very helpful.
I'm no where's near an expert, just someone who saw a dramatic improvement in performance. Long Shot Precision products might be a good place to look at.

Also, you mention the sticky rubber feet. Those will screw up the shot. I ended up putting furniture glides under the feet and there was a noticeable improvement. You'll like the sled feet.

 

[Pseudohero]

Propane torch. 20 seconds per side for fairly circumferential heat. distal threads. Came off easy. Barrel touchable hot immediately after. Why have I not tried this before?

 

[Pseudohero]

Also this is standard 5/8 thread. Not 3/4. Bought it this year. Going to direct thread for now. Looking at the J mac custom hub adapters. Gives you the same points of failure as a direct thread along with a sacrificial baffle and a brake when unsuppressed. you can permanently attach it with Rock set. One issue I see if you’re moving the suppressor is that you’re using the threads on the can itself which is the serialized part. It would be hard to cross thread it, but it’s a consideration.

I should add I'm no expert either. I talked my wife into spending big $$ to train with Chase, and I feel blessed to have been able to get so much knowledge so quickly, as well as avoid costly mistakes. I still have much to learn.

You, as well as I, are blessed to have wives that understand. I'm really lucky to have a wife that is a shooter also. She, in many ways is a better shooter than I and goes along with the $$ of this craft.

So who's the good lookin' guy on four paws? My two won't sit still for a shoot, they just love to play in the woods.

 

[ohiofarmer]

Has it ever been answered whether or not Barrett licenses some portion of LMT’s patents to produce the MRAD? The similarities in the monolithic upper and barrel retention system are pretty stark.

There would be absolutely no need for that. I’m sure LMT‘s patents only extend to AR style uppers as there’s plenty of prior art for the retention system.

Anybody have the Barrett .30cal bore guide and use it with a 6.5 barrel?

 

[Sgtsideways]

Anybody have the Barrett .30cal bore guide and use it with a 6.5 barrel?

Yes, I have it. One thing I'm not too thrilled about with the guide is the metal tube construction w/ O rings. I'd rather it be a composite like delrin. It is nice that the butt end of the guide fits the chassis well. Just kinda bothers me with the metal to metal contact in the chamber. One other thing they should have added is a side port for adding cleaners.
If you can find a similar guide made of delrin or similar (would have to be long and that's the rub), let me know.

I ordered a custom rod guide from PMA Tool, though you'll need one per parent case size.

Is anyone experiencing POI shift on the MRADs through use?
I've the Mk22 ASR setup with Badger C1 rings the Mark 5 scope.
I zeroed, then attended a tactical match on the weekend and found my POI had shifted .3 high and .2 left.
As part of the competition, we aren't allowed to leave the bolts in the gun, so between serials i had to open the receiver, remove the bolt, move to the new position, open the receiver, insert the bolt again. Could this be causing POI shift?
It seemed to be pretty consistent and my spotter was calling it so I still managed to get back on target but i went and confirmed today and sure enough, impacts were high left.
Is there anything specific that might be causing this?
The gun is babied so hasn't copped any knocks and isnt' carried/lifted by the optic.
Cheers
Carso

Have you tried a different scope, with just some rings? Opening the receiver should in no way impact POI as it's the whole upper. What is your barrel torqued to?

 

[Zigjib]

Barrel is torqued to 140"lbs using the Barret Torque kit. Same with all rings and mounts etc.
I'm more worried about the shock of closing the receiver on the optic, rather than just the act of opening the receiver.
I've heard some complaints in other areas about the MRADs having POI shift but this seems to be a solid zero shift as opposed to varying POI in different positions.

Temp or elevation change? Are you running a Kestrel?

nah it's not temp. It's a solid zero shift. Was pretty strange. Confirmed at 100m after the match.

 

[schmi015]

There have been some statistically insignificant internet grumblings. I would mount it to a vise and hook up a target cam and run a it through the elevation and windage dials and see if it jumps.

 

[schmi015]

For this mk5 7-35 the elevation error is so minimal but I'd be curious how high your dialing and how much back and forth you're turning knobs in a match.

Nothing crazy mate. Just what I'd consider normal range use. Certainly no back and forth during serials

Have you swapped scopes and had it out and attempted to recreate the shift?

 

[Shooter50]

I just received my new MRAD soft case/drag bag. I contacted Armageddon Gear and requested the soft case that they are making for the military's new Mk22 ASR (MRAD). A great design that will fit in a hard case and also can be used as a drag bag. It also comes with removable shoulder straps on the back which makes it even more versatile. A great bag made in the USA.

Thank you! This is a four year old post but it solved my dilemma. I'm ordering from barrett the MK22 case and foam for my MRAD and barrels and it does not come with the soft case. I couldn't find it for sale on barrett store. Searched snipers hide and DONE. back ordered but found it. Now $449.95 . I will confirm with barrett tomorrow if the case they offer is in fact the one that will accept the soft case.
RETAIL PRICE: $1,200.00
SKU: 32422
"This is the Pelican case for the MRAD MK22 rifle system. It holds the rifle with scope, suppressor, cleaning accessories, 2 additional barrel kits, and 15 magazines." Anyone know ?

I would also add - what mount options might be the best - Clearly we have some points on the gun and i assume QD is the way to go, but curious what is actually being used in the real world, unlike my unreal world where hauling a 20lb gun is not actually something you need to train to do before doing it. This might be my new work out plan.

Only sling I find tolerable is a biathlon sling. I'm pretty sure mile high has them. It rides like a back pack so if you packing gear it kind of gets in the way of that. I hunt light as I never leave my property so it's great for that. I hunt primarily with a scar 20s and occasionally a TRG 42 so it's very convenient for a heavy rifle. The mrad is so heavy though I think I might hire a sherpa or a pack donkey to carry it. Lol

Fondled one of those yesterday. Is that the stock mount that makes it sit up so high on the rail? Be nice if it sat a little lower. Has any one thought to mount on the side of the forend?

I have carried for coyotes in an eberlestock backpack and it was fine, sling wise I have a padded backpack sling that works awesome, otherwise a 2 point and AR carry style works well too. Its heavy but not as heavy as carrying sleeping children for hours so I'm used to it haha

 

[Ravn83]

Hi,

Does anyone know about any aftermarket rear stock that fits MRAD? I saw a video on YouTube where it was fitted a stock that had more adjustment. Particularly that you could rotate the recoil pad. I feel for my own part that the rifle twist into my shoulder pit when I shoot with 338. It also looked much better.

We would be a new America - About 100 lbs lighter on average just from walking - let alone pack and rifle.

That sling is ok. It's not my favourite but it works. I'm not a fan of those slings that have a bunch of loose straps and tensioning parts flapping around. The Magpul MS1s are the go to normally. They work for retention, carry and unsupported positions without having having loose bits about.

[Sgtsideways]

Just received a .308 Win barrel for the MRAD from a vendor, and realized that the barrel has a 1-8 twist as opposed to the 1-10 twist that I have had in the past. Since I shoot mostly 185gn Berger OTM's, I ran the calculator on Berger's website and the stability factor is well above 2. Also, will heavier bullets, like the 245 or 230 gn Berger bullets even fit the magazines, let alone the capacity of the cartridge brass? Looks like powder charge may be a problem with volume fill.
Figured that you guys with more experience, might be able to assuage my concerns.......Thanks

 

[TheOE800]

Not really your question at all, but the factory 1:8tw shoots FGMM 168gr lights out, at least close in.

To me it just seems like Barrett didn’t bother buying any stock for their .30cal inventory other than 1:8tw.

That may very well be the case about inventory. Waiting to hear from Barrett on this.

Hey mate;

The bergers are totally sick through the 1/8
We've been pushing them out to 1000y in the 17" with the Factory GMM ammo loaded with the 185s.
The kestrel has us trans at 800m and sub at 1000m in standard atmospherics.

The heavy bullets will fit your magazine, but it'll depend on just how long you want to go. Having said that. We compared the 185s to 200, 208 and a bunch of other heavies and the design of the 185s is so good that they typically performed better than the BA predicted and made the 208s etc very very similar to the 185s. So much so we just gave up on trying to get the heavies to fit typical mag length and just went with the 185s.

We haven't done the Ammo test in the 17" barrel yet due to the primer shortage but the 16.5" will be close enough for comparison's sake.
