    I would never buy a <10.5” 556. Thats what 300blk is for. The blast and reliability are the two biggest reasons.

    Also, if I need something tiny, Ill probably just use a pistol.

    Lastly, Im beginning to think what you lose in terminal ballistics can be “made up with” in many situations with speed and maneuverability. Something offensive would be different, but for surprise defense use, getting a holstered pistol out and on target is going to be faster than digging out a rifle.

    Under 10.5 with a 556 you are buying a range toy in my opinion. You are money ahead to get some type of PCC if you need a working gun.

    That blast hurts, you better be running dual ear pro.

    Yup. Both of these are what I was getting at.

    I guess ultimately, a 7.5" 5.56 is a limited role niche weapon with serious drawbacks, but in 300 BO is probably just fine. Which was my perspective from the get go. Some folks just need to justify their purchases.

    I honestly don’t like anything less then a 14.5” barrel.
