Geissele’s High Speed Selector Shown at SOFIC

Known for their triggers, handguards, and a variety of other high-speed products, Geissele has been a long-time favorite of the special operations community. With their SSF (Super Select Fire) trigger being in many a firearm, the company has been expanding their offerings based on feedback from those Tier-1 units.

Responding to a USMC study that showed full-auto fire is more effective at hitting moving targets, Geissele has set its sights on getting the operator to full-auto faster. In the study, the USMC concluded that while there was higher moving target hit probability with fully automatic fire (let’s face it, what targets are generally standing still on a battlefield), too often critical time was lost from recognition of the target, manipulating the safety/selector, and ultimate engaging the target to the point that targets were behind cover before shots were loosed.

Reported and photographed over at our friends Solider Systems, Bill Geissele and team went to work on speeding up the time to engagement. Their solution? The High Speed Selector, which seems an obvious (and welcome) option for operators operating. In short, the High Speed Selector ditches the 90-degree throw in favor of the now common 45 degree throw. Thus, but using the thumb and not breaking their grip, one can go full giggle switch in almost no time flat.

    Translation: Incoming $100’s of dollars for selector switches.

    Verdict: Game changer.

    • Phillip Cooper

      Neba bin dun befo!

  • MeMyselfI

    Useless for us owners of semi-auto rifles. The only thing slightly interesting on this post is to see Geissele is making his own lower receivers. Wondering why – if he doesn’t sell them (never saw any for sale), and only uses them to test its products – why go the trouble ?

    • S Spitz

      As a owner of a gun with the giggle switch it’s of great interest to me.

      Would have been nice if they had a price point on it.

      • codfilet

        Deep-pocketed owners of full-autos shouldn’t have to ask the price of anything…..

    • Gary Kirk

      Because, they can manufacture non transferable machine guns for r&d, just like you can order a lower for the same purpose but it has to be returned or destroyed at the end of testing for a new product.. So instead of paying to purchase a legally transferable lower at considerable cost.. They just mill their own test rigs..

    • John

      Here’s to hoping they eventually offer a binary trigger with this selector.

      • noob

        I wonder if studies will show that binary is actually more effective than full auto for getting the most hits on target per second.

        • Sunshine_Shooter

          I feel like semi-auto would still put more hits/second on a reasonable target than either binary or full-auto.

          I would like to see the tests, though. Anyone have some transferables and a pile of ammo?

        • Phillip Cooper

          That would depend on who’s funding the test.

  • Peter Nissen

    I would like a link to that UMSC study “purporting” that full-auto fire is more effective at hitting moving targets. Is the UMSC going all “spray and pray” on us. Might as well break out the reserve stocks of PPSh-41’s if we are going down that path.

    • It’s not public. I wouldn’t worry about the USMC abandoning the rifleman philosophy, though.

  • LCON

    So looks like the USMC might be moving to M4A1 after all.

  • supergun

    Just get an Echo trigger.

    • Blake

      …are you really suggesting that the military ditches a fully automatic mode for a binary trigger? Really?

      • supergun

        Civilians can not have automatics. Most of them anyway. Have you watched the video of an Echo in action. Looks as close to any automatic that I have seen, and is probably more accurate. Next question please.

        • Blake

          Yeah that is just… massively incorrect. Pretty much any person who is capable of owning a gun is capable of owning an automatic gun (as long as they don’t live in the small number of restricted states). Yeah I have seen video of them, and no it’s not going to anywhere near as accurate as a gun with an auto mode. We live in a dimension where physics exists, and where repeatedly slapping the trigger is going to make your groupings massively larger than someone bursting with an automatic firearm who is just holding the trigger down. Not to mention the most important aspect of accurate full-auto fire – leaning into the weapon – is not going to be repeatedly accurate with a binary due to the inconsistent cadence of fire.

          This is all setting aside the fact that this article was about a new potential M4 upgrade for the *military*, not civilians. Next thing I need to massively correct you on please.

          • supergun

            Blank, you remind me of a friend I had in grammar school. He was probably the most intelligent boy in the school. Most of the kids did not have anything to do with him, but we clicked. He probably became some research scientist that made a hell of a lot of money. Most people don’t want to spend $20,000 for some automatics. Most people don’t want to pay the kind of money that could be used to buy guns instead of paying the toll tax to the democrats. Most people would not like the idea of the FBI being able to search your home without a warrant, which is what you give up if you have automatics. I could go on and on, but I don’t have the time that you do, to talk much about nothing and nothing at all. If that was all I had to worry about, I would have it made. The military encourages 3 shot bursts instead of full auto anyway. The Echo is the perfect trigger, because you don’t need full auto unless you are going to rob a bank and plan of dying.

          • Blake

            You’re missing the point and arguing completely moot issues. I agree that most civilians don’t want an automatic gun enough to buy one, but I was arguing against your statement of “civilians *can’t* own them”. And as far as automatics not being useful, that’s just wrong too. Besides suppressive fire being far more effective when automatic, USMC studies have also found that automatic fire is far more accurate when engaging moving targets. And all of this is completely moot because the article and original comment were about soldiers, not civilians.

          • supergun

            Good night, Blank.

  • DanGoodShot

    Man… I wanna play too!

  • Ark

    The whole “USMC study says…” bit reeks of marketing BS. A fancy selector is not going to make any quantifiable difference in the real world, nor will it make you a better shooter.

    Also, lol, fancy selector, fancy bolt catch, fancy charging handle, and…A2 grip? Bro do u even oper8?

    • pun&gun

      I’m not sure I’d dismiss it out of hand. It’s quite a bit of finger movement to turn the standard safety a full 180 degrees, and when your targets are bolting for cover as fast as they can, I could see how replacing that with a quick flick could be beneficial.
      The pictures I see of A2 grips on otherwise-tricked out rifles still mystify me, though. XD It’s mind-boggling that in a world of affordable (and even cheap) ergonomic options, some people actually like that plastic brick enough to keep it.
