PRODUCT DETAILS

The PMAG 30 AR 300 B GEN M3 (https://www.magpul.com/products/pmag-30-ar-300-b-gen-m3-300-blk?utm_source=GL9%2021&utm_medium=GL9%2021&utm_campaign=GL9%2021&utm_term=GL9%2021&utm_content=GL9%2021) is a purpose-designed magazine for rifles chambered in 300 Blackout. Since it’s inception, 300 Blackout shooters have had to use a magazine designed for another cartridge, limiting it’s performance and compatibility. One of the nice features of 300 Blackout is the compatibility with 5.56x45mm parts, but with the magazine it is a compromise to do so. Due to the wide variety of projectile weights and shapes potentially decreasing overall reliability, a dedicated 300 Blackout magazine was a logical step for the PMAG line.

In addition to the performance gained by a dedicated mag, the PMAG 30 AR 300 B (https://www.magpul.com/products/pmag-30-ar-300-b-gen-m3-300-blk?utm_source=GL9%2021&utm_medium=GL9%2021&utm_campaign=GL9%2021&utm_term=GL9%2021&utm_content=GL9%2021) also offers a safer way to feed your 300 BLK rifle. When using 5.56 mags, the potential to chamber and fire a 300 BLK round in a 5.56 rifle with catastrophic results requires diligent ammunition management by the shooter. The PMAG 30 AR 300 B’ (https://www.magpul.com/products/pmag-30-ar-300-b-gen-m3-300-blk?utm_source=GL9%2021&utm_medium=GL9%2021&utm_campaign=GL9%2021&utm_term=GL9%2021&utm_content=GL9%2021)s distinct rib design provides the shooter a distinct visual and tactile difference from any other PMAG to mitigate dangerous cross-loading issues. Along with optimized 300 BLK performance, the PMAG 30 AR 300 B brings along all of the GEN M3 features such as our next-generation impact and crush resistant polymer, aggressive front and rear texture, an easily removable slim floor plate, a paint pen dot matrix for marking and identification, and a dust/impact cover.

• Dedicated, purpose-designed magazine for rifles chambered in 300 Blackout
• Optimized internal geometry accommodates the wide variety of bullet profiles used in 300 Blackout cartridges
• Distinct rib design provides the shooter a visual & tactile difference from any other pmag to mitigate dangerous cross-loading
• Carries forward the physical & performance features of the rest of the gen m3 line

Just out of curosity - anyone here that shoots 300BLK with PMAGs, ever have any problems?

Supers and subs, no issue. What I've heard has issues with PMAGS is the subs with round noses.

Yup.

[BoilerUp]

Interesting. Are people having feeding problems with their 300 BLK? I've never had a feeding issues with mine and haven't been seeing a lot of complaints on the interwebs, but this suggests that Magpul believes that for at least some portion of the market the 300 BLK isn't delivering on one of its promises. If Magpul would make a purpose-designed magazine for the 6.8 SPC, I'd buy it, but this product is more likely to create a problem for me (a new calibre specific component) instead of solve one.

[SINNER]

Had a few over many rounds. I use a few mags specifically for .300 so they get used heavily. And smokey. lol I'll still buy a bunch of these.

I wish it was a normal 6.8 mag. I've not had a problem with 300bo in large and small pills.

Part of the appeal of 300 was that it required only a barrel swap. Not it's a barrel and a mag. Next will be dedicated 300 bolts...

And to think that after SHOT last year, Ken Hackathorn said it appears the 300 was dying... not sure what he saw but it seems to be exploding.

[Uffdaphil]

I hope these eventually come in sand. It would be comforting to dye all my 300BLK mags a unique color. I do like the large recessed panel below the magwell for a sticker or paint.

[JoshAston]

I wish it was a normal 6.8 mag.

That won't happen. Not enough room in the magwell, that's why the Six8 mag was designed from the ground up as a 6.8 mag and then the magwell was designed around it.

You don't need dedicated mags. The PMag was the only mag on the market having issues and then only with a few certain bullets. Any mag without the internal rib will work perfectly fine with .300.

Maybe I interpreted it wrong, but I think what he means is, with the creation of dedicated 300BLK mags, now manufacturers are going to start creating dedicated 300BLK parts - all as a marketing gimmick.

Precisely.

Plenty of factory 6.8 ammo fits in the normal magwell.

My comment is simply that a standard 6.8 mag would better serve the industry than this. My 300 rifles shoot fine with gen 2-3 pmags.

[Joelski]

Didn't we recently decide that Magpul was above pandering to the tacticooly privileged?

[JoshAston]

The ammo fits, but it also takes up more of the magwell than 5.56 does. This leaves you with not enough room to make a 6.8 PMag that fits inside a STANAG magwell.

so far this is the coolest thing of the year and I don't even own anything in 300BO.

[Deadwing]

I use the translucent Lancer AWM mags for shooting 300 Blackout, and only 300 Blackout. Zero chance of misidentification for a mag loaded with 5.56.

I did test a bunch of 300 Blackout ammo ranging from 110gr supers to 220gr subs through various magazines when i first started shooting it. All rounds fed flawlessly through everything from USGI mags to Lancers to Gen 2 and Gen 3 PMAGs.

[Uffdaphil]

I dedicated my translucent Lancers for the same reason. Also added rubber ID bands as an added reminder. Hopefully it will get to the point where just picking up a mag without the band will feel wrong. I still worry about grabbing the wrong Lancer in dim light and have too many to designate all to BLK.The black mag is a D&H 300BLK specific that I need sell or paint something garish to avoid mixups. If these new Magpuls come out in sand I would switch to them and dye a unique color.

[Deadwing]

The rubber band is a good idea for cheap insurance. The vast majority of my AR mags are either USGI or PMAGs, so it was easy to dedicate my Lancers to 300BLK duty. I've got some black Lancers squirreled away someplace, but none are in use. The number is small enough that I should probably dedicate those to 300BLK as well and eliminate any chance of a mix-up.

I've got a pile of D&H 5.56 mags. What's different about the 300BLK version? Just the follower? Or did they actually make changes to the mag body?

[Uffdaphil]

Yes, they changed a guide rib inside. From the reviews it seems some have problems with certain projectile shapes. I have not experienced issues I can be certain are mag related.

From Wilson Combat site:
New D&H Industries 30 round aluminum AR-15 300 Blackout/7.62X40 WT optimized magazines.

These magazines have the internal rib positioned to improve function with a wider variety of projectiles in 300 AAC Blackout and with other .30 caliber AR rounds like 7.62X40 WT. Because these magazines are based off 5.56 parent magazines they will still feed and function in 5.56 rifles as well.

These quality military grade magazines feature a slick black Teflon finish and Magpul anti-tilt follower.

Sweet mercy... $23 a piece!

I think i'll give the Magpuls a whirl, or keep using my 5.56 mags.

[Joelski]

Leave it to WC to figure out how to sell a $7.50 mag for $23!
