If you don't have a dedicated suppressed home defense setup, then a 7-9" 300 blackout is a nice addition to your toolkit. Just do a little home defense scenario larping when the wife and kids aren't home and you'll see how much of a difference it makes to navigate the corners and spaces in your house with a shorter barrel and suppressor.

Ex: My 8" 300 blackout with suppressor is still shorter than my 13.9 P&W 16" carbine by over 1.5" without a suppressor on it.

Sure, there is the MK-18 as a solution. But 5.56 gets real gassy at shorter barrel lengths and you'll need to tune your buffer weight, spring, and preferably your gas port.


13" 308 is cool, but what's the real application scenario there? Is it going to be a hard-hitting battle rifle that brings more oompf than 5.56 in the same range territory 5.56 normally covers?

I wish we saw more manufacturers doing 13.9 or 14.5 barrels in 308 expressly meant for pin and weld. I freaking love the length savings on my 5.56 with a 13.9 barrel.
