Having an issue removing the stock muzzle brake on my new MRAD 300 Win Mag barrel ... photo below. I've removed many brakes on many rifles, but this one won't budge ... and I feel like I'm missing some nifty trick that one of you MRAD gurus might want to share. Any advice?

Loosen the nut behind the brake first, then try again on the brake itself. It's a self-timing type.

You must be talking about like a super early serial number, I've got an older one circa 2013 and it pinches the barrel around the extension.

Does anyone know of a short bolt on rail panel with a not rotating sling cup?

I hate that its spins freely I’m always untwisting the sling. I don’t even need the pic rail just the QD mount cup.

It's a long Lapua case head cartridge that you can fire 338 or 375 bullets out of, should work fine in an MRAD, albeit single fed

Interesting ... seems like a lot of cost and customization, for minimal advantage. Certainly an option that resides with much better shooters than me. Pretty happy so far with my MRAD in 300 Win Mag and a 338 Lapua conversion kit. This photo is from yesterday's 300-WM session where I made 4 shots through basically the same hole at 100 yards (working on groups during this visit). Still getting acquainted with my MRAD ... getting it "tuned" and "zero'd" for a ELD shooting class/clinic in Utah in April. Don't always shoot this well, but this result seemed photo-worthy.

- MRAD 300 Win Mag (Fluted)
- APA Fat Bastard Gen 3 Muzzle Brake
- Hornady ELD Match 195gr (Factory)
- Velocity 3015 fps (Labradar)
- Winds light and variable

The advantage is 300gr 338 projectiles and 350gr 375 projectiles at 3100fps...

It's more than a minimal advantage at ELR distances.

On the flip side I've thought of selling a couple rifles and buying more conversions for my MRAD and barrels for my match gun.

Does anyone use this bore guide ( https://store.barrett.net/p-5417-mrad-bore-guide-30-2-o-rings.aspx )?

I have the new MRAD .308 config. I've only seen the .338 breech guide previously linked in this forum though.

Also interested in a bag rider if anyone has one. For those who already use them, I'm just curious how you like it and if you use it all the time or just occasionally?

That guide is the same as the Dewey guide for the .338. I’ve emailed Barrett and they offer the .338 and .30 cal guide thru the store and I was also pointed to Possum Hollow Bore Guides for custom made guides. I placed an order with Possum Hollow and will post pics and details of the products when I get them.

Okay, thanks for the info, I'll definitely look at the PH Bore guides. I think I'm going to buy the one offered on Barretts store. They just don't have product photos so I wasn't sure if they were the same.

Do you remember the last time Barrett had the riders in stock?

My 6.5-CM conversion kit is on the way. Got the bore guides for my 300-WM and 338-Lapua barrels. I'm assuming the 300-WM bore guide will work on the 6.5-CM barrel. No MRAD 6.5 bore guide that I'm aware of ... right? Anybody know of one?

Right, it's not very clear. Have you asked Barrett directly? I haven't heard anything from them. I'm interested in this as well so if you find anything out please share.

Also, if anyone has an extra rail rider before the BFMI store has it in stock, I would be interested in purchasing one. If not that's fine too.

I'll know later today ... when I mount my new 6.5 barrel and give it an initial pre-shooting cleaning (using the .300 bore guide).

Confirmation ... the Barrett (Dewey) 300 Win Mag bore guide ... works just fine on my new MRAD 6.5 Creedmoor barrel conversion. Nice tight fit, O-ring seals nicely, only sticks out of the receiver about 3/8 inch from the way the 300-WM version seats. Plenty of support and holds in place nicely. FYI ... the 338 Lapua version does "not" fit the 6.5 Creedmoor (or 300 Win Mag) barrel, and hangs too far out the back end keeping it from being stable. Hope you guys find that helpful.

Had a great time with some friends stretching out the MRADs legs out to 1000 yards. The wind was more then we would have liked for a first attempt (15 mph, gusting to 21mph) but we all managed to tag the gong. The DTA had a 16 inch barrel, and I swear the impacts barely had enough energy to chip the paint lol. regardless, my buddy and I were both very happy with how the MRADs performed.

Barrel calibers ???

Anyone that has .338 LM, which do you prefer? The 20", 24" or the 26"

I'm looking to purchase a conversion and I'm curious if the stability and maneuverability of a shorter barrel is the way to go. Interested in what everyone else has/ thinks.

For me I went with the 26” for .338LM. I wanted it to have the legs to run as far as I could push it. For a shorty I’d just go with .308. My new love is the 300 Norma Mag. I just started using. 😍

The 26" looks badass as well. Curious how far you're pushing the .338 and 300NM? Right now I'm mainly shooting the- .308 22" beings I'm stuck on a 100yd range at the moment. But I was planning on getting out to Nevada and I'd like to have something I can send downrange 2000yds + with a little power remaining in the round.

So far I’ve taken the 338 out to 1100yds and on a nice day and with hand loads it will shoot sub MOA easily. It has shot a few sub 1/2 MOA groups out to 880yds. I’m not good enough to do it all the time. (Learning how to read the wind ) My hand loads are pushing the Berger 300 otm close to 2850fps so it’s good to at least 2000yds. I’ve only shot the 300 Norma mag 60 times so far using factory burger ammo. It’s got less recoil and is right on the heels of the 338 and so far out to 350 yards to 300 Norma mag is a laser.
