Home Forums Hunting & Shooting AR and Tactical Rifles What's the deal with the 30 Remington AR?

Is it dead? Was it ever alive? On paper it looks like a decent round in that platform.

Good question. I am not sure but I think it came along at the wrong time.

.300 Blackout pretty much killed it.

Performance is close enough and you don't have to change bolts or mags.

Not hardly:

The 30 Remington AR is a nice idea, just too much competition to make it relevant. The 30 Remington (vs the 30 Remington AR) is largely dead.

Wonder how that OSSM feeds in an AR?

I would assume the same as the other WSSM cartridges. D-Tech builds a lot of them, I have no personal experience.

The 30RAR was an attempt to take advantage of the Freedom Groups already flagging 450 Bushmaster. A barrel swap was all that was required to switch calibers. Any chance it had was certainly killed by the 300BO. All of these niche cartridges are hampered by the same issues and will never be the commercial success the 300BO has been. There will always be those guys who spend untold sums of money shooting and reloading them. That Olympic cartridge is nothing short of an abortion.

I called Stag and ask them if they were ever going to offer a Bolt and Carrier in LH for the 30 AR and they said never . After their reply i wrote the 30 AR off and built myself a LH 300 BLK.

Remington supported the RAR about like they do everything else...they didn't and it is dying because of it.
The 300 blk and RAR are both 30 cals but that is where the similarity ends. The 300blk is slower than a 7.62x39 and the RAR is almost as fast as a 308. 300-400fps isn't even close to the same performance.

The 30 RAR is in a different league than the 300BO regarding ballistics.

The 30 RAR offers a 600 fps velocity gain over the 300BO with 125 and 150 gr bullets.

That's a wider spread than comparing the 308 to the 300 WinMag.

The BO is just a bit above 30 carbine level performance (in my opinion), however if you shoot magic bullets like the 110 grain VorTX it performs well for deer.

as has been said many times on this forum, still many don't understand, the bullet and your ability to shoot makes a lot of difference. I have seen 150's out of a 30-06 kill a deer but not exit, I have seen 60 grain TSX 22 caliber bullets shoot thru similar sized deer, I have seen deer lost with big 30's etc.

I consider the 300 ACC a rifle to just play with and i don't take it really serious for hunting, even tho i believe it is capable if you stay under 150 yard with the 110 to 125 gr bullet . I built mine for calling coyotes in the woods. To tell the whole truth i built it because i didn't have one and wanted to see what all the hype was about. I'm using the Speer 125 gr TNT with Lil'Gun, it shoots ragged holes at 50 yards the longest i have grouped it on paper.

I mean to get a 300BO upper put together one day myself. Seeing as I already shoot the 208 Amax in the 308/30-06 rifles, it seems like the only right thing to do....grin.

its capable sub sonic with 194 lehighs to 150 no issue, so I suspect super sonic with the 115 barnes rounds it should be a 200 yard no issue round at a minimum.

maybe the next Military round for the M4

Despite the industry's use of the term Modern Sporting Rifle, I just don't see the need to make the AR do things it was not designed to do. If I am going to hunt deer I am going to bring a bolt gun(actually I usually bring a bow) with ample power, you know, like a 30-30. (do i really need to add a smiley to make people get the joke?)

I have a 300 BO only because I bought a suppressor and the 223 was far from quiet.

Don't under estimate the 300 BLK it is better than the little round would make you think by just looking at it, kind of like the 357 magnum .

that is me, I like to try new things. So far the BO with the 110 Vor-TX is 1 shot for 1 dead deer.

I see the appeal of the 300 BO for use in a suppressed rifle, which is what the cartridge it is based on was designed for specifically. I was more looking for something for hunting and general shooting that had a bit more punch while maintaining the nicer qualities of the AR-15 platform vs. the AR-10 style rifles with the added weight and size. I've looked at the .25 WSSM uppers, and they are neat, but the whole concept looks to me to be something that no one is going to carry very far unless they are training for something.

From what I've seen, I'm guessing it's dead?

The 300 BO is great for doing whatever a 7.62x39 can do as well, not just subsonic/suppressed stuff.

If you really want more power in an AR platform, the 308 is a pretty sensible way to go, and doesn't have to be that much heavier. I have a pair of 223 and 308 ARs set up almost identicaly (SS15 handguard, same Leup scopes, Magpul stocks, etc) except for barrel length (18" 308, 16" 223), the 308 is right about 1 lb heavier. It's also slightly larger in most dimensions, but not unmanageable.
