Introducing 300 Blackout Wilson Combat® Rifles, Uppers & Barrels! PICS!
Introducing the latest Wilson Combat rifle caliber, the 300 AAC BLACKOUT (300BLK). This new caliber was developed to reliably launch 30 caliber projectiles from the AR platform without a reduction in magazine capacity and to remain 100% compatible with the standard bolt. The 300 AAC BLACKOUT is optimized for sound suppressor use with supersonic or subsonic ammunition.
Full power factory 300 AAC BLACKOUT 123 grain ammunition easily matches the ballistics of the 7.62x39mm, has 37% more energy than 5.56mm M855, and 9% more than 6.8 SPC TAP 110. From an SBR barrel, the 300BLK has more muzzle energy than 5.56mm M855 from a 16 inch barrel.
When 300 AAC BLACKOUT is used in a 16 inch barrel, it has 23% more energy than 5.56mm M855 from a 16 inch barrel - with much higher-mass projectiles for a more dramatic effect on the target. Subsonic loadings are optimal for use with a sound suppressor that vastly outperforms a typical 9mm carbine in penetration and long range accuracy.
Due to the high efficiency of the cartridge, less powder is used than 5.56mm, which results in a rifle that is a comfortable to shoot - even with a short barrel. Reloading dies available from Forster products. Loaded ammunition is available from Remington.
• Create a reliable compact 30-cal solution for the AR platform
• Utilize existing inventory magazines while retaining their full capacity
• Create the optimal platform for sound and flash suppressed fire
• Create compatible supersonic ammo that matches 7.62×39 ballistics
• Provide the ability to penetrate barriers with high-mass projectiles
• Provide all capabilities in a lightweight, durable, low recoiling package
Ideal for hunting, tactical or SBR use, the 300 AAC Blackout is destined to be the ideal choice for suppressed AR use.

Wow is all i can say. You guys hit it out of the park on that one.

can you use standard USGI mags with this round?
Also, the barrels state that they are optimized for sub sonic ammo, will higher velocity not shoot well in these barrels? any plans for a chrome lined barrel?

My guess is they are pistol length gas systems.
ETA: I see now where is says pistol gas system on the third barrel. That would be my guess though as the pistol systems cycle subs betters
Please excuse my ignorance, but is this any different from J.D. Jones' .300 whisper, or the copycat .300 Fireball? In any case, I love this concept, and I hope this iteration is successful enough to get some major ammo makers on board.
Ok...color me confused.
I just got an email back from you guys today. I was asking about what gas port size you used and if I might need an adjustable gas block to run mostly supersonic (e.g., the factory Rem 123gr. loads and the like up to about 147gr. ball). I asked such things as:
What size gas port would such a barrel have?
Would an easier (and perhaps better) solution be to just buy an adjustable gas block (I have used PRI ones in the past with good luck)?
What size (internal diameter) gas blocks do your lightweight barrels require (the common 0.75”, or other)?
Here's the response I got today:
"We don’t have anything optimized, or even suitable for supersonic ammunition."
Now, I think I could live without "optimization" becase I assume that your "supressor-built" barrels would have a larger gas ports than ones geared toward supersonic loads. Thus, I could put on a PRI adjustable gas block and be GTG...right? It's just the last part of your Reps' response that got me here...
***update –– followup from WC on 2/11***
Here's a follow up asking them to clarify (for reference, the 16" bbls I was asking about have carbine-length gas):
Chris,
The concise answer is the specific market segment we are pursuing is subsonic. There are barrels out there that are better suited to supersonic use, ours is not one of them. Rather than sacrifice quality by trying to be "good" at many areas we would rather be "the best" at one.
Thank You,
XXXXXXXXXX

I post this only as info for those trying to figure out what barrel will be best for the type of build they have in mind. I wanted to go with a WC bbl, but it seems I will have to look elsewhere. YMMV.

There are several already producing ammo (Remington has 2 loads, BTW). Do a search –– even google - and you'll have a night's worth of reading.

I'll wait until it gets passed the flavor of the year....
Just assembled a WC 300 blackout lightweight 16" barrel last night, I used the PRI low profile adjustable gas block and the port size for my barrel was .106". Used a Troy/Vtac 11" battle rail handguard and it fit fine, the set screw for the port lines up with the slot in the rail for easy adjustment. I need to make up some brass and load some cartridges to check it out, hope to have some time this weekend. Will be using Redding 300/221 and a set of modified 7.62x40 Hornady dies first to see how they work. Have heard mixed reviews on the 300 blackout dies from Forster so would rather not buy them unless I have to.
Hope this helps.

That was close to the build I had in mind –– I would be interested in how well you get some 123gr and 147/150gr. supersonic loads to function in it.
