No way in hell Id trust reliability out of a 5.56 platform under 10.3".

The reliability? It’ll still be reliable, you’re just not gonna have the same energy and velocity you would out of a longer barrel. Plus with it being a pistol build its suited better for close quarters anyways soon need to worry about long distance.

Since it’s clearly not designed for hunting, more of a close quarters range plinker or up close engagements when “shit hits the fan” the 5.56 will still have more then enough power to take down any human regardless of barrel length. People don’t have the hardynest of large game

I'm a huge PSA fan! Their website says that these are temporarily out of stock, though. {:>(

Waiting on the 8.5. Seems they build these and 10.5 most of the time. 8.5 stainless with MBUS to go and I am in.
