AAC SquareDrop Freefloat Handguard

“Needs” and “wants” are frequently interchanged by consumers in the firearms industry. As in “do I really need another pistol?” For the majority of us, I am going to postulate that the ‘wants’ outweigh the ‘needs’ nine times out of ten. In similar fashion, I could pose the same question to manufacturers. Such as, “do we really need another type of attachment system for AR handguards?” Probably not, but AAC is banking on the fact that you might want their new SquareDrop freefloat system available in three different lengths.

I for one am not of the fan of the Keymod attachment system, so I am happy to see an alternative that is also backwards compatible with previous accessory rail sections and attachments. Being a fan of Magpul’s MLOK system, I can’t help but wonder if AAC Has made the SquareDrop silently compatible with that system as well.

Either way, the system looks like a complete package that is both attractive and well made. Will it be the next must-have accessory for the AR platform? Only time will tell.

The AAC SquareDrop Handguard is a proprietary 100% free-float attachment system that allows infinitely adjustable mounting positions for any Keymod or SquareDrop accessory, enabling you to create your own mission specific configuration. Offered in 8″, 11.2″ and 13.5″ lengths, the unique SquareDrop Handguard features extended alignment flanges to ensure a repeatable fit eliminating torque or rotational force movement. Innovative turnbuckle mounting design allows users to quickly and easily install and remove rail system. Full length internal ribs offer superior strength and durability. Smooth snag free design eliminates “cheese grater” effect. Assemblies include handguard, barrel nut, turnbuckle and install wrench.

    As long as it doesn’t have the same problems as keymod and costs about the same (or less), I’m on board.

    finally a rail for authentic honey badger

      Except this one might be compatible with the other 14 standards. 😉

    It looks to be potentially worse mechanically than regular keymod, using keymod accessories…

    So people buy this thinking it’s a better looking version of keymod, only to later find that their old keymod stuff does not stay tight… Forcing them to buy new crap…

    Unless this can prove itself stronger than m-lok I don’t see it doing very well.

    Magpul backing m-lok has pushed it to the lead quickly over the existing keymod, that had a several year lead.

      “Magpul backing m-lok has pushed it to the lead…”

      Magpul created MLOK.

      • iksnilol

        Yeah, that’s why they’re backing it. Duh-doi.

      • marine6680

        Yeah, that is what I was implying…

  • Frank Grimes

    My god.

    Every time those pierced face tattooed covered freaks stay off the junk long enough to “invent” something that already exists and is already stupid, they manage to increase the stupidity of it ten-fold.

    Very honey badger, especially the mounting system.

  • MrBrassporkchop

    How about molle handguards and picatinny vests?

    • steveday72

      You can get a Molle->Picatinny adapter plate. Will that help? ;o)

  • iksnilol

    Squaredrop: at least it doesn’t look like male genitalia.

  • mig1nc

    I wonder if they will release a fat version that will be able to cover a suppressor, basically the actual Honey Badger rail.
