Anyone using the 300 Blackout round yet?

OK, I just ordered a barrel from Ole's gun shop in Salem, OR. I was talking with some people on Arfcom and one of the guys there highly recommended them. I found some other good recommendations online so I gave them a call and talked to the gunsmith who produces them. He seemed very knowledgeable and had a lot of good recommendations so I went ahead and placed an order.
I'm going to be getting a 10.5" barrel built off of a Shilen blank, with pistol length gas and 1:8 twist to stabilize heavy subsonic bullets. Apparently if you're going to run suppressed subsonics in a barrel this short you need pistol length instead of carbine to function reliably. Kevin (the gunsmith) asked me to send in my bolt so he could headspace the barrel extension to my specific one. With AR's headspace usually isn't a problem as long as the extension is in spec, but he said proper headspace is critical to accuracy with this cartridge so he likes to headspace each one individually. According to him .5 MOA accuracy is pretty common with a good barrel in this cartridge, with some examples shooting as well as .25 MOA. Good thing I have an extra .223 bolt laying around.
Price should be around $220, which is dirt cheap for a Shilen barrel. He also chambers Green Mountain blanks for about $50 less but for that price I couldn't pass up the Shilen. It's not unheard of to pay twice that.
Guess I had better start working on that stamp for a can.

Check this out. Pretty sweet. If you're not familiar with the Honey Badger joke just go to youtube and search for it. Honey Badger doesn't give a *#!% ;D

So it's threaded same as a 223 barrel, right? Think that's same as a 9mm piston on an Osprey... ;)

Nope, it's threaded 5/8-24, same as a .308 barrel. That's to keep you from running .308 caliber bullets through a .223 can or brake.

That makes sense. While nothing is foolproof, that sounds pretty idiot proof. So you're looking at...
5/8x24 piston: $75
fixed barrel spacer: $45
45 Osprey: $850
Tax Stamp: $200
Add to that a little sales tax and the BATFEIEIO waiting period and you'll be in silent but deadly by next summer!
