AR-15 in .300BLK (300 Blackout)

[esrice]

Oh, and for those wondering if the .300BLK has some punch to it, just ask the dueling tree and those that witnessed it.

This was my second time shooting .300BLK (the first time is shown in the OP).

I was extremely surprised at how hard the rounds were hitting the steel when compared to hits from .223. Part of the time was spent shooting a dueling tree, but we had to stop because the paddles would simply bounce back into place after being walloped.

Stranger still was the fact that it delivered that kind of punch without any noticeable difference in recoil (compared again to .223).

Justin gave me one of his .300BLK rounds as a souvenir. When I pulled it out of my pocket at home later that evening I noted how much heavier it felt in the hand. I set it on my dresser to taunt me into another short upper.

A few more pics. . .

You and me both! I just have to decide, a short 9mm or the .300blk upper first? I can drive 3 minutes and shoot the 9mm, it takes me over an hour drive to shoot the rifle calibers...

Short .300BLK upper. Buy a .22 conversion for your .223 if you wanna shoot close by.

I already have 2 conversions. As you're shopping for yours, shop for mine as well. I guess you saw my 2 additions to the NFA timeline thread. Both are designed with the .300BLK in mind.

That rail on jblomenberg16's CMMG was interesting. I'm not a fan of the anemic mounting system, but it was SUPER thin and had a good feel to it. Then he had to go and show me what it looks like on an 8.5" upper. . . .

I was trying to start you off slowly. . . .

I'm REALLY glad they are out of stock!

I'm days away from getting my SBR stamp and a few expense checks away from getting that Noveske 8" barrel.

The next big question is do I get a real 30 cal rifle caliber suppressor or just stick with the subsonic through the 9mm can. Hmm...

I think you should get a real 30 cal can. Until then, you can keep doing the subs only through the 9mm can though

Looks like it is working now. 147gr FMJ ammo for $12.99 / 20. Not bad at all for new ammo.

 

[jblomenberg16]

Is it here yet?

It is now. Haven't moved onto blowing things up yet, but this is a good start.

**sigh** if they were only in stock.

If I order one now I wonder if it would come before I get SBR approval...

I know what you mean. If I could find a barrel I like, I'd go ahead and build one. Heck, I can't even do that!

Now that I have my stamp you can just ship it to me. I'll grant you full visitation rights.

Hmm... wondering if I should let loose of some info...

I can't say who yet but there's a small well known manufacturer who will be making 300 BLK barrels and my H&K style 3 lug 9mm pistol suppressor will fit right onto the end with no adapter needed. If your Google-fu is strong you might be able to figure out who I'm talking about. I can't say yet.
