300 Blackout AR-15
I am building a 300 blackout AR-15.
Can any one give me tips?

I'm about where you are. I've got a Franklin Armory lower and i just bought a Daniel Defense 300 upper. No ammo . .

I guess the tip is ammo is pricey and hard to find! It's a nice alternate to have in my opinion.

Assuming you guys could even find the ammo, what would it cost? I bet way too much.

Here is my tip; Find out what ammo IS available, and try to find an upper that will shoot it...

Agreed. Start looking for your ammo. I'm learning that lesson now. Supersonic only for me as it's my understanding subsonic is for suppressed use only

$1.25 a round Not cheap

nope its not supressed only. some lighter loads pretty much duplicate 7.62x39 performance.

it is however a round that is best if your a handloader and are willing to make your own brass from 223/556 brass

Never made my own but it's on the to do list now that I've got this upper. I don't regret buying it but i wish i would have gotten some ammo first!

I just picked up a Smith and Wesson MP15 chambered for 300 Blackout/Whisper. I also have a hundred rounds of 220 grain subsonic and another 100 rounds of 115 grain coming. Continental Arms in Maryland has a whole shelf of the 300 blackout ammo. It's not cheap either, I pay $23 bucks for a box of 20.

I have 500 rounds of factory 220gr sub sonic and about 1000 rounds of reloads that I have loaded up! I plan on using this AR to hunt hogs! Will post some pics as build progresses along only have upper and lower and barrel should be getting parts in mail all week!
