    I purchased a banish 30 suppressor, states it isn't recommended for 16" or less due to first baffel premature wear. It's marketed like a 308 suppressor… Would you think 10-12" 300 blk out is safe to use/ have you experienced suppressors damaged with short 300blk? Wanting a 300blk gun for hunting, want simar size as a 30-30 in length with suppressor. Thanks for any input

  2. Every time I watch u video I’m like “I need to live somewhere where I’m on a lake and can shoot outdoors near by”. Passion 1 bass fishing, #2 shooting! Neither very conducive to living in shitwhole Philadelphia

  3. Thank you. This video helped me decide. The Tactical Games just approved 300 as an ammo option, so I bought a 12.5" BCM 300 barrel, to swap out in my 12.5" 556 build. Will be my first 300. Let the games begin. Cheers!

  4. Been eyeing this upper for a pistol build.. Would this still be classified as a pistol when the OAL goes over 26" (SBA4 brace, normal carbine buffer, etc)? What's the legality of that?

  5. Awesome channel sir. Wish BCM would (1) offer a fully nitrided option (exterior, chamber, bore), and (2) have slightly less gaudy brand markings on the upper.

    I’m in the market for a 12.5 .300BO, and still deciding whether to build yet another or press the easy button and buy one assembled. I have a nitrided ToolCraft BCG already, so checking if BCM sells complete uppers sans the BCG.

  6. Sounds like their lightening choices for the barrel profile is costing them some accuracy. I ran the same federal ammo you did with less than 1.5", and that's with a standard 30 cal profile DD 10.3" at 1:8" twist.

  7. Great video and I have a video on 300 Blackout at the range and it will shoot 1in MOA with well made ammo. My video show 3 brands squaring off and 1 brand is impressive the other 2 brands are not nearly as good 👍. Thanks for sharing.

  8. I have a question I've been hearing that running a suppressor shortens barrel life, as it blows gases back into the barrel causing the barrel to get even hotter than it normally does , thus warping the barrel and harmonics, have you heard anything about this?
