If you go back a few pages some Barrett CS emails are in here. Just reach out to them and they’ll get you a label for the rifle and you’ll be fixed up quickly.
The "New" Barrett MRAD Thread!!!!!!
- Thread starter IanHusaberg
- Start date
So if I don't have a dimple on my MRAD I need to call Barrett to get an upgraded chassis? Or just the MK22
I have this exact weapon 2.3k rounds using 6.5CM 139gr Lapua reloaded, never had a single failure with it nor with the firing pin. At some point it comes down how you use your bolts and take care of 'em, the millitary will find some issues with the mk22 that you'll not see in the civilian area. Heads up most people don't take care of anything that is granted to them because they did not spend any money to play/train with it.
I already got a RMA to return my chassis. No complaints best service I’ve seen from a gun company.
Barrett store info is such a disaster to get sorted. Not sure if it helps, but my AML338 compatible brake has a 1" OD at the muzzle (1.013" measured) and on the wrench flats (1.000" exact). I suspect it is the 18404, but it came with my 300WM barrel so I'm not certain. Same dimensions on my 300NM barrel, too.

Thanks for taking the time to get the measurements. I'm getting .9855" across the wrench flats and 1.243 across the threads. My calipers are getting low on its battery so the measurements may be a little bit off. I sent an email to Barret asking for an explanation of the two models. If I hear back, I will let you know.

I purposefully bought a pre MLOK version MRAD because I thought the chassis just seemed more robust. I've since upgraded all parts to the current versions and got the 2-stage flat trigger. Are there any known issues of the chassis cracking in the pre MLOK version?
It’s worth mentioning that video is of a brand new mk22, and that trigger failures were observed in the first 1000rds fired. What do you think was poorly maintained on the rifle?
I’ve never seen or heard of any issues with non-MLOK rifles.
Unfortunately the video was deleted. But before it was I was reading a lot of the comments and someone said they were just new uppers at one of the sniper schools. You know how that goes though, someone says X and someone argues Y lol.
Deleted for fear of repercussions from command probably!
I personally think the failures are less user inputs and more design. Just my assessment.
I've already saved and reshared the video, and it is listed here in the previous comments above. Correct, these are not poorly maintained rifles. Just like @JustSendit said, these are practically new. It is not a maintenance issue.
Norma 230gr and Berger 215gr factory ammo. All 5 shot groups, bottom left group has a low/right sighter from my unsuppressed zero. All groups shot with the AML338 can.
Can somebody explain the trigger issue (and how you'd attempt to reproduce it) in simple terms?
I'm not a high volume user, but I'm just curious what to look for should anything ever happen.

Unsure how to reproduce it as a few seem to have tried on here with no results.
Just examine your trigger pack every so often, pop the pin out of the pack and remove the sear and make sure it’s not dirty inside of it. Reinstall. You’ll most likely never have an issue.
Two MRADs and 8,000 rounds with a mix of calibers and never had any issues like that (or others to be fair).
Can you only see the dimples when it smiles?
That's my smartass way of saying I have no flippin' idea what you're talking about.
I'll read "up" and see if I can find something.
If I recall correctly, the dimple referred to is an indentation just below where it is stamped T30 Plus on the chassis.
I didn’t have a clue either and it could just be a false sense of security for all I know.
That’s what was said to be the indication of the new receivers.
I can only speak to my issue. The magnum magazine would release the cartridge prior to the bullet tip entering the chamber and lay flat and get the bullet tip pushed into the base of the barrel. This caused it to be unreliable, it would work but had issues -especially on the last round in the magazine. My assessment is it only applies to short magnum calibers. I don't know anyone else who is shooting a 6.5 PRC (or similar cartridge) in an MRAD. My 300 PRC works perfect. 308 based cartridges - perfect.
Quick range report regarding POI shift;
Earlier there was some commentary regarding a POI shift based on front support/bipod location. There is an ongoing thread in the Semi-Auto sub-forum where folks are talking about this and testing it for themselves. I am using a recent production MK22 rifle, 300 NM barrel, with the AML338 suppressor. I have a full length ARCA rail. After moving the bipod as far forward as possible and then rearward, I observed zero measureable shift in my groups.
If anyone has observed different I'd be interested to hear their testing protocol to see if I can recreate their results.

I am very interested in the MRAD platform and I am considering selling a couple other rifles to consolidate into one multi caliber Barrett system.
I have a question for all you MRAD aficionados. Does anybody know what the largest ELR cartridge is that will reliably mag feed from the MRAD? Or inversely, if bolt heads/magazines become available, what might be the smallest cartridge that would work in the MRAD ELR.
I would like the flexibility to shoot higher volume, less expensive .308, 6.5, 300 NM but the option to shoot larger ELR cartridges as well. Is this a pipe dream, should I just plan to get an MRAD and later an MRAD ELR?
I think it would be cool to have the ELR but with a smaller/lighter caliber to practice fundamentals, with lower cost per round. Then put on the .416 Barrett and send it.

The largest cartridge it will feed is 338LM or 338NM. I have a Cadex build with 33" barrel in 41XC, which requires single shot loading due to length of the 41XC cartridge. I'm getting 2870 fps with a Warner Flatline 505 gr in that build. I was eyeing the MRAD ELR but was disappointed to find out the Barrett 416 cartridge has lower velocity with the same bullet in its 36" barrel. It's an expensive option for less performance and the only advantage over my Cadex being the ability to mag feed. You can actually run a 41XC in the standard MRAD since it utilizes a 338 lapua cartridge diameter but it won't mag feed. Several months ago I had Bugholes spin me up a makers kit with a 28" 41XC Bartlein barrel but still haven't had time to do the load development on it yet. But pushing a high BC 505gr from the standard MRAD platform at even 2750 fps (estimated) with the shorter barrel really appeals to me, even if I have to single feed it. You can definitely get on target at 2 miles with this setup. The 505gr is a beast at one mile, with more ft-lbs than my 308 has at the muzzle.
Thats sounds amazing. While it would be convenient to mag feed, a smaller, lighter rifle that can run smaller cartridges as well as something like a 41XC, single feed may make more sense for me than a larger, heavier rifle that can only do the big stuff.
I wouldn't mind having both but I am running out of room in the safe.
Anyone have experience with the Carbon 300 PRC barrel conversion? I’d like to see some photos of the barrel installed.
There is a dude i found on ebay that can 3d print you a mag shell and then insert the mdt mag into... I'll post some pics tomorrow of what it took to run wsm/saum cases.
I worked with this guy, it’s ugly but I can shoot wsm and saum cases now.

ok, New to MRAD. My first...Way more info on here than I can digest quickly at my age(60+)
I have 2 quick questions and I only went back to December of 2024 on the thread, so hoping for some help.
1st...is there anyone that makes a reasonably priced bore guide for these? Barrett $70 and Dewey makes one for 338 reasonably priced but I have 30 cal barrels.
2nd... I would like to use one of my already owned suppressors, but I'd like to use the existing threaded muzzle brake that came with the MRAD. it looks like a larger version of the Q type threaded taper mount. I have standard thread rear suppressors so I'm hoping someone can shed some light on what and who makes a mount /adapter/rear suppressor cap for the muzzle brake?
Thanks for any input. I'll be reading up on these threads to get educated a little more on this interesting rifle system.

Dewey makes the Barrett bore guides. If you ask them they'll make you a 30 cal bore guide, just put it in the notes of the order.
I'm not aware of any third-party cans that are compatible with the Barrett brake. Remove the brake, install what you need.
