[ARCHIVED THREAD] - 300 Blackout Question

Posted: 12/27/2012 1:26:52 PM EDT

I am wondering if anyone has built one of these? If so what setup did you purchase? I think this would be a great setup. Did you do anything different to your lower like a heavier buffer or just run the same lower as a normal AR15? Just trying to get something different before they try to take our guns

Thanks in advance

the only thing that is needed is the barrel . EVERY thing else is standard 223. (an exception may be a gas tube , I am using a 16 inch barrel with a pistol length gas system)

I use a lighter buffer because the standard buffer didnt function 100% of the time.

Stainless ar-stoner 1:8 twist 16in medium profile barrel
Fail-zero bcg
Spikes upper/lower
Yhm rifle length forend/low profile gas block
Standard buffer/spring
Moe stock/grip
palmetto lpk/di tube
aac 51t breakout

That's the way I build mine. Took down a spike last night with it.

Thanks it runs rather well, its my favorite rifle right now. I also forgot to add that I put in yellow jp spring set in it. 300 rds so far with zero failures on cci, remington primers and hornady factory rounds.

I've got a Noveske 10" that I'm running with the following: Auto carrier, standard Brownells CS action spring, ST-T2 buffer.

So far I've only run supers through it as a pistol build and it runs perfect. Need to get some subs to try and may change out the action spring to a standard weight Sprinco white spring.

I put one together using all off the shelf 5.56 parts, other than the barrel of course. Standard buffer, bolt, etc. Had the carbine length gas system. Runs 100% prefect. Oh, and I ever do my own ammo using 5.56 cases. I have a little production line set up....

See this is why I like this place. You guys are awesome! That is awesome so I can get another stripped upper and then just switch with on and off with my 5.56 and I am set. Did anyone have any headspace issues with adding the barrel to a stripped lower?

I hope you meant adding a barrel to a new upper and not "lower." As long as you use a new bolt with a new barrel from reputable manufacturers, I can't imagine that you'll have a problem. I try to keep bolts and barrels in matched pairs if they've been shot more than 500 rounds or so.

Sorry I didnt explain myself fully. I meant that I would build a 300 Blackout Upper and just put it on my normal AR lower

Posted: 12/28/2012 5:14:19 AM EDT

[#11]

That'll work just fine.

Here is my 10.5" 300 Blackout and my 10.5" 5.56 Upper. Just pull a pin and slap it on the lower. Lots of fun.

Awesome. Now I hope I can get a stripped upper to finish this up LOL

Built this blackout using a Sota arms 16 inch barrel, Surplus Arms upper, Yankee hill gas block under the handguards, Armalite clamp on A2 front sight base......PSA bolt carrier group.........

Killed a Doe a couple of weeks ago with this setup using Nosler 125 ballitstic tip and 18 grains of H110.......

This is great. thanks everyone for sharing. I will do this LOL

Except for the barrel, all standard parts.

Changed my mind, went with longer handguard.
