    This is really awesome that you are using a new block for each round. Thank you for incurring the expense to bring us this much education and entertainment (edutainment).
  • For those of us trying to keep track of which guns are being used: Mark 18 -- 10.3 inch barrel, 5.56 mm Quickhatch -- 8.1 inch barrel, 5.45 mm SIG Rattler -- 5.5 inch barrel, 300 blk Arsenal SAM7K SLR -- 8.3 inch barrel, 7.62 mm FAL OSW -- 11 inch barrel, .308

    Would really like to see the 300 black tested with supersonic ammo. Using subs in one caliber and supers in the rest is not an apples to apples comparison.

    Team 300 Black here. Being able to instantly switch from crazy quiet subs to very respectable supers, without having to change a thing on my gun, makes it the most versatile for me. Caveat - I hardly ever shoot past 300-350 yards.

    Ive never been more excited for Mike to show me the results of something so short !
  • @matthewmason831
    Damn, .300 blackout should’ve had supersonic options tested too. Great video!
  • @tommygunn3260
    Video suggestion: if there’s a SHTF situation and you can ONLY grab 1 rifle & 1 pistol, what are they? And what’s your kit? I think lots of us wanna know!

    This was one of the most subtly funny yet informative videos I've seen. Great job guys

    Every time that I go to order gun parts I hear Michah saying “primary arms” in my head so that’s where I order things from now.
  • The informational and gear videos will always be my favorite, thank you for the knowledge Mr. Thumb
  • Wow, this is an amazing vid sir. Absolutely stunning the results with the 545. 556 also very stout on the gel. 300blkout punching through the block was awesome and 308 did work on the block! Awesome content this was great thank you!

    Everyone always asks, "Where is Charlie?", and not "How is Charlie?"
  • @CatTechSupport
    300 and 8.6 Blackout are the quietest options you have.
  • @jakesalerno1932
    Awesome video! Would have been interesting to see how a SBS 12 gauge would have compared the the various rifles.
  • @robertbernard651
    This is a question I've been trying to get an answer for 15 years, excellent clip. Thanks 😊
  • @TheTopGun920
    300 Blackout is my preferred round for SBR, but man 308 is such a beast.
  • @lukeletkeman8835
    The accuracy issue on the AK wasn’t the ammo, it was the MRO😂
  • @tiredoldman
    .300 Blackout is probably one of the most effective round for an SBR. It was designed for that purpose. I’ve used various SBR’s during my time in the Corps and even own a few. The SBR is meant for close quarters and short ranges. I really appreciate the video though. It’s especially helpful for those who are new or have little experience with SBR’s. I watch your videos often, this is just one of the rare occasions I have something I think is useful to add.
  • Great video. It's a shame the 7.62x39 rifle was being so fussy. I'm partial to that caliber in shorter barrel lengths.
