AAC 300 Blackout Uppers In Stock

Mike, congrats on the XDS, brother!

 

Now, here's my $0.02.  I can't see why you'd build a 300Blk upper.  To swap onto another lower, that the 20" lives on already?

 

Why not just build another lower.  Then you have two complete rifles, instead of 1.5 rifles.

 

 

I'm just sayin'...

I am going to hold off on 300blackout I have 3 5.56 guns and the ammo for the blackout will chamber in a 5.56 gun and my wife is not as savy as I am and she enjoys just going out in the yard and blasting a few round and that may be a case for a potential problem still thinking about it.

You won't be able to get a Blk round to chamber, brother - it won't seat and the bolt won't close.  The .30-cal projo will stop short of chambering in that .223-sized chamber.  If the bolt's not fully seated, the rifle won't fire.  <thumbsup>

watched a guy do it yesterday, if the crimp is not strong enough it causes bullet setback and the bolt fully closed and would indeed fire it caused a setback of approx. 35 thousands he was using 150's, now i realize this was reloads but their are alot who do not crimp as well as a factory load so for me right now being as they are the same mag etc i am going to pass till I get the wife up to speed.. then If factory ammo ever gets where I can afford it I will have me one iknow it would be a perfect match with my 762-sbn-6...

We do the same here

Red =5.56

yellow= 7.62x51

grey= 45acp

green= 9mm hers....

 

right now those are the only calibers we have in quanity in boxes of over 20, hunting ammo is in boxes of 20 like 270 or 308...and 7mmSTW will not fit into anything else....  my concern is out shooting both 300BO and 5.56 that she or I for that matter might get one or the other in the wrong mag.... I will discuss it with her and see how she feels but it is a concern to me after all I am getting older while my memory is getting shorter... lol
