    It’s been a while since I checked the ballistic calculator on my given ammo but I seem to recall that it slows below the speed necessary to fragment somewhere around the 200-225 yard mark when fired from a 12.5” barrel. I could be mistaken though.
    Maybe. But the bullet will still make enough of a hole to cause a notable leak in the hydraulic system. Add to that, if a foe were to take offense at having such a hole put in their hydraulic system, they'll have to have to cover that 300 yards or so to register their complaint, risking more leaks being placed to greater effect.

    I have read on numerous occasions of our guys putting bad guys down with MK18's at 200 yards. Of course I can't verify that.

    There was a whole thread on here several years back about an article detailing the increased use of Mk18s in Afghanistan.

    https://www.m4carbine.net/showthread...OF-on-MK18-use

    I think that it's fair to say that an SBR/10.5" or so barrel is still perfectly acceptable for most combat ranges a 5.56 weapon will need to engage it. Beyond 250-300m, it's best to get something a bit bigger. (be that caliber or longer barrel, I leave to another thread) That article/thread finally got me off my ass and caused me to invest in an SBR barrel for my SCAR, and a DD Mk18 upper AR pistol.
    It's f*****g great, putting holes in people, all the time, and it just puts 'em down mate, they drop like sacks of s**t when they go down with this.

Frankly for those who’s job doesn’t involve kicking doors down, and SBR to me seems more of a toy than anything.
    Do you own an SBR? 14.5” or 16” is general purpose for whom? You? Its not for me. Personally a 12.5" with a LPVO and a can would be my general purpose rifle. I would add that accuracy has nothing to do with barrel length. Velocity and the range of your given ammo has to do with barrel length.

    But lets take that whole argument out of the equation. If you need to make a head shot at 100 yards and your gun is 4 or 5 moa, that could very easily be a miss. If your short barrel bullet hose is 1.5 MOA, its a shot you can be confident in if you do your part.

    It wasn’t until reading that other article on the MK18 that I realized Dano is no longer on this forum. I had noticed I hadn’t seen posts from him in a while...now I know why. Sucks to lose the SMEs who have actually BTDT.

    Completely agree. Such a bummer.

    On using the Mk18 at 200+, guys aren’t doing that because they have 4 guns in their backpack inventory they can switch to like a videogame. They’re using it because its the gun they have in their hands at the moment. Not because its the optimal tool for that particular shot. They are carrying it because the benefits for their task outweighs the drawbacks.

    Soldiers, even well trained ones, tend to overestimate distance in varying degrees, especially at night. So when I hear about a longer shot that I wasn’t present for, I think about how they determined/verified the distance, time of day, and who’s telling me.

    Also, ammo type can play a role, as does chance and placement. Pop a melon, and it doesn’t matter if your ammo fragmented or expanded optimally. And dropping a dude like a lightning strike has a different scale of urgency at knife range than it does at “that idiot can’t hit me” range. Nobody likes getting shot, so a dude dropping face first to the ground at 300 does not always mean he is DRT. It may mean he doesn’t know what to do about his current problem, and hopefully he’ll be dead when you get to him. Of course, you’ll never find out if you shoot him a few more times just for luck.

    I’m not saying that any of these reports are BS, or that the Mk 18 doesn’t do the job, just providing a little clarification. Choose what works best for your task.
