F4 Tactical Rail-Mounted Pepper Spray

New from Pro-Defense is the world’s first rail-mounted pepper spray system. Called the F4 Tactical, it mounts to a Picatinny rail and is capable of spraying either short burst or a continuous stream of pepper spray up to 20 feet. The F4 Tactical has a snap safety similar to ones found on most hunting rifles as well as a second buffer safety spring. It comes with one 2 ounce canister of Sabre pepper spray. It retails for $99.99 and is available in black, camo, pink and safety orange. Check out Pro-Defense.com for more info.

    Dear Grand Jury; I actually wanted to spray him, but pressed the wrong trigger. I am very sorry.

    • noob

      It’s okay. All you did was set his eyeballs on fire by turning on your Crisis Intelligence Alpha-1 50W LED searchlight you had the pepper spray mounted to.

      actually, if you were in a place less permissive than the California (but more permissive than Australia where pepper spray is LEO/licensed security guard only) a flashlight/spray combo might have some utility as a home defense tool. Certainly less likely to cause permanent injury than a baseball bat.

        Attach a ZiP to one of the other rails, just in case.

  • Dan

    If I’m not mistaken, for a non-LE to utilize this product outside of a situation in which leathal force is already justified would constitute a Felony.

    • Vhyrus

      Depends. Not every state has laws about pointing guns at people, and since it is too big to go on a pistol, the assumption is that it would only be used by non LE in a home defense situation. I am pretty sure if someone broke into your home you could point pretty much anything already legal to own at them.

  • wetcorps

    So if you want to use it on someone, aren’t you supposed to “muzzle something you don’t want to destroy”?

    • bbmg

      This, mounting a non-lethal weapon on a lethal weapon does not seem like a great idea.

      • dude

        And yet, doctrine says all nonlethal weapons will be backed up by immediate availability of lethal weapons. Like Stingers in the M203 while the rifle’s loaded.
        But then, nonlethal isn’t. That’s the inherent problem with the designation. If you point a taser or mace or whatever at a target, you’re pointing it at something you want to destroy.

        • Dave The Great

          “intend” or “are willing to.” People who “want” to destroy something are psychopaths.

    I have just invented a rail mounted signal device that, when activated, will summon my Mom to the trouble area where she will assault the attacker with a large wooden spoon.

  • gunslinger

    why. i don’t see why pepper spray on a rifle is a good idea.

    almost like those 12ga less(non?)lethal rounds (maybe taser?) oops. loaded my defens round instead of the taser round…

  • Michael Pearce

    This is a supremely bad idea. If someone points a gun at me in a threatening manner, I am justified in using lethal force in self-defense. It doesn’t matter whether they meant to spray me or kill me; what matters is what is reasonable for me to believe.

  • hami

    I imagine in reality this would be used on non-lethal weapons. For example coupled with a bean bag gun.

  • Mike

    This is a colossally bad idea.

  • Andrew

    Obviously this was invented by someone who was never in law enforcement, has never been to a staffed gun range, never had any formal firearms training, and just doesn’t have a clue about safety in general.

  • Anon

    Pair this with a rail mounted taser and have it on a that p90-flashlight thing and BOOM perfect less-than-lethal weapon

    • Mazryonh

      We have rail-mounted tasers already. Rail-mountable Taser X26s have been seen on TASER International’s X12 shotgun, and I’m sure they’re working on making rail-mountable multi-shot tasers available for long guns soon.

  • BA47

    Eh, seems too unwieldly for what it is to me.

  • Shayn Striegel

    i was speaking with pro defense as SHOT show for awhile about this product. It is more designed for police and military in peace keeping operations. If you’ve ever been in a situation requiring the use of both lethal and non lethal capabilities it would come in handy. Say clearing a room in a school with a hostage situation our controlling the street of a grey city. The product itself is shit. It was a poor design and feels like it could easy be ripped off of the gun. If it had a more stable design i would consider buying one but because it feels like a toy i will never.

  • Ivan Kurniawan

    Want to see pistol-rail mount compact version.. I think it’s work well in this configuration althrought the spray canister capacity more limited.

  • guest

    Comming soon to a protest suppression task force in a city near you!

  • Mazryonh

    All this talk about the dangers of “muzzling” someone with your long gun makes me wonder about “standard operating procedure” with other underslung less-lethal weapons, like the FN 303, where you had to muzzle someone with a lethal long gun if you wanted to aim the attached less-lethal weapon. Does it say anywhere in the “rules of engagement” that you should set your lethal gun to “safe” if you are trying to get an apparently-unarmed but unco-operative person to comply with your less-lethal underslung weapon, so as to minimize the chance of lethally shooting him/her?

    And where did they say the safety switch on this “pump-action” pepper spray was in order to keep one from unintentionally discharging it? Can the inert training versions of this spray be used to “mark” people who run away from an officer-involved situation so as to identify and catch them again for questioning, just like certain tactical paintball rounds can?

    No your honor, I really meant to spray the suspect, really
