    with 223/556, a legal SBR also does the following neat and fun things:

    - lower velocity

    - increases ballistic drop

    - decreases stopping power

    - decreases reliability

    - greatly increases noise/blast/flash

    - tax stamp adds cost/time and adds your name to some fun lists

    - limits areas of country you can own or travel with it


    (ok, ok, i like 'em too, but honestly, unless one needs a shorter handier barrel (or has it in a canned 300BLK), its more about forbidden fruit and having the coolest toy on the block)

    ((oh no, i can hear all the nasty comebacks already....))

    Indoor use and OAL with suppressor is my primary reason. I'll never own anything else.

    Stopping power?

    Overly generalized.

    Actually, I thought it would be cool to have one but in the end I opted against it. I ended up splitting the difference and went for an SR so that when I finally receive my 'tax trust' I'll be able to shoot with less noise.

    ok, i'll bite: when doesn't decreased velocity lower stopping power?

    agreed and why I own SBR's

    Personally, I built mine for HD. It's a suppressed 8.5" 300blk. The 300blk was made for such instances. It's a lot easier to handle and maneuver indoors.

    He's saying it is overgeneralized because there is ammo out there made for use in shorter barrels that negates this.

    Overly generalized perspective.
    If talking velocity-dependant projectiles, like SS109, 55gr FMJ, and the like, then you will be able to see a difference.
    If using modern, purpose-designed projectiles, those differences will be greatly reduced until you get outside the prime performance range of 5.56, and you would be hard pressed to see a practical performance difference out to 200 between 11.5 and 16 inch barrels.
    Most velocity dependant projectiles also suffer from fleet yaw variability performance degradation anyway, which is why most professional users have moved away from those designs.

    This is by no means criticism, but what do I not understand?

    Easier to get on target?

    Handier than an AR with a 16" barrel?

    Please, clue me in as I've don't know what the appeal is.

    Thanks!
    They are less common. You see stuff like this all over. For example, a vehicle forum I am on, people are paying stupid money for euro spec headrests for the second row seat. No lie. Why? They are slightly smaller and not offered in North America. Its acrazy. So that's one appeal.

    The second is all the team guys are shown in military photo shoots with mk18s and hk416s with 10.3s. So there is a bit of hero worship and "they use it so it must be best for me, too! " mentality.

    The 3rd reason is that the user is a swat member or someone who uses a suppressor most of the time and works in structures and vehicles quite often or any combo of the above.

    I personally have no use for sbrs really. Owned a few. Saw no real benefit.

    There are many reasons I like the shorty ARs, (not one of them being the forbidden fruit thing) but the biggest reason is that I enjoy shooting them. Beyond that, all other reasons are secondary. That's true of anything I shoot and I don't care if I have a practical reasons beyond pure enjoyment. Practical reasons can come later. If you want to know what the attraction is, go shoot one. It's enjoyable. So is shooting a shorty AR suppressed. Or in full auto. Be careful of shooting suppressed full auto shorties though, it's nearly addicting
