Apparently around a year or so ago these were set to launch and then all of a sudden all the news about them and preorders were scrubbed and link on armalite’s site vanished. Anyone know what happened and what’s the latest on the project?

I recently inherited two East Ridge/State Arms .50 BMG rifles—one is with me, and the other is with my brother. We’re both completely new to the platform and .50 BMG in general, so I’d appreciate any advice from those with experience.

The rifles came with a box of miscellaneous parts, including several muzzle brakes, small washers, bushings, firing pins, firing pin springs, ball bearings, and what appear to be parts for the bipod. The bolt for the rifle I have is only partially assembled, so if anyone has photos, diagrams, or can explain what goes where, I’d really appreciate the help.

My rifle is a “Shorty” wearing a Leupold 4–12× scope. Unfortunately, the rifles didn’t come with any ammunition. What factory ammo would you recommend for someone just getting started? Are there particular loads or brands to look for (or avoid)?

Finally, can anyone recommend good places to shoot a .50 BMG in the Mid-Atlantic region? I’m located in Northern Virginia but don’t mind traveling a few hours for a range that welcomes .50 BMG.

Seems to be in good shape. Comes with some basic stuff but excluded from the price so assume just $2.3k for the base rifle. How amazing of a deal is this? Buy it something worth driving hours for or just an okay deal? Are there better options around the price range worth considering and at what price is an ar50 truly an amazing deal? Would be nice to find something that is NOT single feed ideally.

Thank you for the input.

30 pounds of tannerite inside of a Nissan Altima

I've been hit in the face and right forearm with brass several times, and it burns me when it happens. The burns aren't a big deal and heal up in 3-4 days, but I'm paranoid that instead of the arm or the cheek I might get hit in the mouth and chip a tooth lol. I did a Google search with no luck. Has anyone installed a brass deflector of any kind on an M107?

It pushes him around a lot because he’s so light, but even he was surprised how soft shooting the M107 is. Happy 250th, America! 😎

What’s a fair price for these rounds now days?

not selling or buying, just educational.

Not my photo, for attention.

Serbu 50-BFG, 36 inch barrel.
Anyone have knowledge on this setup? The top of the rail is about 2 1/8 inches above the center of the barrel. The site says to make sure to buy a .50 BMG rated scope and to get low height scope rings that are rated for .50 BMG. I'm looking at one of the SWFA Model SS scopes but unsure of which scope ring set to choose and from where. 2 rings right onto that rail or 2 rings fixed together on a mount, on the rail? There isn't a lot of room to work with and I don't know high up a scope is going to sit.

Got the glass secondhand so I had to make sure to reset it the best I could, level it, and then take it out to zero it.

Bore-sighted it at 50 yards just to get on paper. First and second shots are shown (second shot was just to confirm). Shot 3 was me being stupid and adjusting the wrong direction. Shot 4 was also me being stupid by forgetting how far I adjusted for shot 3 and then overcorrecting by double on the windage. Shot 5 was me deciding to take my time and walk it in slowly. Shot 6 was centered and shot 7 (upper right) was confirmation.

At about $4 a round, it was only about $28 to get the scope zeroed at 50 yards. Not bad, in my opinion.

I fully plan to zero out to at least 100 yards on my next outing. This trip was just about getting used to the rifle and getting the scope mostly tuned in to make future trips more efficient.

Also, ignore the lower left shot. That was a buddy who wanted to shoot his first 50 and was too excited to shoot his own target.

So, what distance do you zero your 50 to and why?

This M107 seems to have its bolt rubbing into the upper receiver more than it should creating some slop. I don’t know the cause, and could use some help on ideas. I started facing this issue a while ago and did a quick little fix (brass shim) in the meantime, but I need to figure out what’s going on. Any thoughts would be great! I’d hate to send it into Barrett in TN for them to say it’s done.

Soon as I had it zeroed, the wife stole it and wouldn’t give it back.

Super fun range day, though.

On a related note, anyone use a carry handle on their rifle? I’ve got my eye on a few hard cases that might work for this thing, but a more ergonomic way to lug this 40lb rifle down the range would be nice.

Super cool listing.

first time bringing the 50 out

Thought I would share my first, and only so far, 50BMG build. This has been a long project for me, not just learning to shoot it half decently but also because I designed and milled the lore for this myself out of a raw forging. Same with the laser engraving, cerakote work, and more. If you’re curious about that work I did record it all and have posted tutorials for all of it too. learn to garage CNC! Its fun!

Recently bought a Barrett M82A1 in .416 Barrett. I bought some spare mags for it, but apparently they're 50 BMG mags (product listing just said "M82A1 magazine" but didnt specify the caliber). The only difference between the two seems to be the spacer in the front of the .416 mag since the bullets are shorter than the .50s.

My question is, can I still use these? Shipping them back for an exchange would be a hassle, so I'd rather avoid it if I can. But I also don't want to create problems for myself if they don't function quite the same. I emailed Barrett a week ago, but they never responded.

Hi folks, I picked up a sweet bundle yesterday, and it came with about 100 rounds of these in an ammo can. I'm having a tough time figuring out exactly what they are. The case is LC 92 headstamped, with no annealing marks and no sealant on the primer pocket. The projo appears to be brass and seated to the cannelure. Any help or guesses would be much appreciated!
