13.7-14.5 300 Blackout barrels

[Whitey375]

I am trying to put together a 300, but can't seem to find the barrel I want, other than a $500 Noveske. I really want a 13.7" barrel with a pistol length gas system. Anyone have a lead for me?

I haven't seen anywhere. Everything for .300 BLK seems to be either 16" or for pistol/SBR they're 9"/10"/12". I might have seen 14.5" at some point in the past but I don't believe I've ever seen a 13.7" in any caliber. Are you sure it exists? Seems too long for a pistol build, too close to rifle length to be worth it for SBR, and too short to bring over 16" with a muzzle device to make it a legal rifle. Are you trying to build a rifle, a pistol, or an SBR? If it's pistol or SBR, you might as well go 12". It's only 1.5" shorter than what you're looking for and more importantly it's readily available.

Here's a pretty nice upper for not a ton of money.

I'm actually not sure it exists. Plan was to pin a KX3 on it to get 16" out of a 13.7. I thought I had seen a Noveske in that length, but who knows. Just didn't feel like paying $500+ for a name that isn't worth it anymore.

Don't blame you. I just checked and Palmetto actually has that 12" barrel by itself in stock right now for $200 ($250 but they have 20% off right now). But it sounds like you are actually wanting a rifle build. Not sure why there aren't any in 14.5/14.7/whatever though. It's a popular length for 5.56. Especially with all the people wanting to put a supressor on .300 BLK and keep overall lenght down. Or maybe everybody that gets a can goes ahead and SBR it while their at it?

Yes, I want a rifle so I can hunt with it. Yes, I know the 6.5 & 6.8 are "better", but if I need longer range, I have other guns for that.

Does anyone know if they count the barrel extension as barrel length, because a 12.5" + a 3.28" KX3= 1/4" too short...

Just buy a 16in barrel with a pistol length gas system and take it so get cut/resized.

Here is a barrel extension that would give you the length you need http://mfiap.com/i-7605745-mfi-m4-blank-style-fake-silencer-universal.html

If it is pinned and welded then it is considered part of the barrel.
