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

This looked to me like trigger manipulation somehow lost control of the sear, and then fiddling with the safety droped the FP/striker assembly...possibly a dangerous situation if it was a complete suprise and happening wrong/time wrong place...etc.

I'm sure its not exactly the same issues, but SIG had a 2-stage trigger on the cross rifle have some kind of similar issue, ie droping the firing pin,

for reference...



step 1 - Manipulates trigger,attempting to fire, rifle doesnt fire.
step 2 - Moves to make safe (open bolt)...and sear drops...live round downrange.

If Barrett is looking at the same scale/scope of issue, they probably need time to figure out a fix, do a recall, and then replace the fire-control units (ie triggers). Sig fixed that issue pretty quick. Its not instantaneous to do these things.

Again not saying any of this is or isn't happening, but its the nature of the things involved that is possible to happen.

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 have the Barrett MRAD in 6.5 CM and 300 PRC. Not sure if the muzzle brakes are the AM 30 or AM 338 models ?
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. Thanks again.
 
Correct. It’s just a small dimple notating the change.
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?

I don't know if anyone else is using the MRAD as a base rifle for "non-standard" calibers... The MRAD loves the 300 PRC but I wanted to change. So I am going to shoot a couple of ELR matches this year in 7 PRCW. The problem I ran into is the MRAD does not like this caliber and it does not feed reliably. So I started exploring my options and found that this caliber will feed from a MDT magnum magazine that has been fit into an MRAD magazine. (weird right?). So far my initial test are great, and its working fine. If you have any interest in this unusual project let me know.

So 6.5 PRC and 7PRCW have issues feeding through the mrad?

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?

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.
 
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.
I didn’t have a clue either and it could just be a false sense of security for all I know.

If I recall correctly, the dimple referred to is an indentation just below where it is stamped T30 Plus on the chassis.
That’s what was said to be the indication of the new receivers.
 
So 6.5 PRC and 7PRCW have issues feeding through the mrad?
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 fully 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.
