KE Arms Picatinny Vice Block

Check out this Picatinny vice block from KE Arms. It allows you to lock your ARs upper receiver in a vice via the Picatinny rail and is pretty handy when trying to align your rail and upper during installs. I swap rails on my ARs all the time and it can be a pain for some types of rails, especially if you you don’t lock the upper down in a vise or don’t have someone else helping you with a second set of hands. At just $9.95 the KE Arms vice block is a small investment that will make your life a whole lot easier if you plan on swapping out rails often. Check them out at

Secure your upper receiver in a vice with the picatinny vice block. This block can also be used to line up the upper and rail of your firearm to ensure accurate alignment when installing the rail. Made from injection molded polypropylene.

    “swapping out rails often” . . . does someone have a problem with decision making? but yeah a convenient way to work on the gun.

        Let’s be honest, guys play with bARbies. You can date an AR based on the furniture and great choices. Rifle fashion changes just as much as clothing fashion.

    • I have more rails than I do AR uppers, I know I have a problem haha

      • Budogunner

        Yeah, you don’t have enough uppers ; )

  • Budogunner

    Inexpensive, and saves some headache for those who build lots of uppers. I call this a good product. I could have used it a few years ago when I had the disposable income to build a few uppers.

    Best tool I ever bought was a YHM (i think) steel picatinny vise… I hated myself for doing so many builds without one. Was like $80 though, this looks like it’ll do the same thing for $10. Wonder how durable it is though.

    So, this would not work too well for barrel installs, right?

    • Budogunner

      Nope. You want an action block for that.

    It’s a VISE block, not a “vice” block.

    A “vice block” is a part of a city where hookers and junkies hang out.
