Does the barrel have a sufficient shoulder behind the threaded muzzle to properly align a suppressor? My last PSA .300BO barrel did not.
Keith W on Jan 25, 2019
Is this flash hider unscrew for a surppressor?

Does this shop to my house?
Brian A on Jan 25, 2019
BEST ANSWER: Yes it will. I ordered a different build kit similar to this one and it shipped to the house without issue. Since this does not include a lower, there is nothing that needs to go through an FFL.
Does this shoot 556?
Patrick on Jan 25, 2019
BEST ANSWER: No it fires the .300 AAC (Blackout) cartridge. Although they share some of the same dimensions (and can use the same magazine), the .300 AAC is a much bigger projectile.
Does this come with building instructions? I purchased this and now I am nervous I won't know how to build it or I won't have the proper tools...
Chandler P on Jan 27, 2019
BEST ANSWER: No instructions. Just get on the net and find some build instructions with pictures.
Do you have a weight on this kit in OZ?

It's lights out for the 5.56! 300aac is where it's at!
This is possibly my favorite upper I've bought from PSA, I wish I'd bought more 300aac stuff than 5.56, this is way more fun to shoot in my opinion.
