Marines Using Geissele Products

A recent solicitation originating from Quantico has come out and is specifically requesting Geissele products. Although the solicitation RFQ is worded as open to the public, it lists Geissele items and nothing else. These are the commercially available “Super Modular Rail Mk7”, and the “Hi-Speed National Match Trigger Set“. Although it doesn’t mention anything about the Marine Corps Shooting Team, the choice of these exact parts and the fact that the Team uses a number of Geissele triggers, I believe it is somewhat safe to say that the parts are intended for the Team. The Team’s headquarters would not comment on the intended usage of them.

On Geissele’s website, both of these product descriptions are worded for usage within Civilian Marksmanship Program matches. The rail having CMP legal features with lead weights and a sling swivel mounted at the end. A catch about the rail system is that the RFQ specifies that it must be able to be mounted to an SR-25 upper receiver with an appropriate barrel nut. SR-25s are rarely used by the Marine Corps Shooting team but they do have them and use them occasionally in High Power matches. Currently, I’m not sure what makes the trigger set ideal for CMP usage as I would assume any finely tuned trigger would be excellent for these matches. The Marine Corps would like to order 10 of the rail systems, and 66 of the trigger sets. It would appear that the 10 handguards would be equipping the Teams SR-25s, and the 66 triggers are for the majority of the team’s M16A4s being used for service rifle competitions.

From the solicitation (emphasis mine)-


CLIN 0001: Super Modular Rail, MK7, SR-25, with lead weights

• Rail must be of quad rail picatinny design.

• Rail must have fixed sling swivel 13 inches from the magazine well +/- 0.5inches.

• Rail must free float the barrel and provide space at the front for a front sight A-frame and gas block on the rifle.

• Rail must be capable of adding lead weight easily with screws or other fasteners so the weight can be altered to accommodate specific shooter preferences and does not shift freely while firing. • Rail must be black or tan in color.

• Rail must have a rigid design so it is not easily bent far enough to contact the barrel while stress is applied by a shooter wearing a sling.

• Rail must come with a barrel nut over 2 inches long threaded to fit the Knights SR-25 upper receiver.

• Rail dimension must be compatible with the optics rail height on the SR-25 upper receiver and must not require modification to be installed on the SR-25 receiver. • Geissele MK7 Super Modular Rail, National Match, Black, w/lead weights

CLIN 0002: Geissele High Speed National Match-Triggers-Service-Rifle-Small-Pin

• Pin location and size should be compatible to Mil-spec for M16A4 service rifle lower receivers.

• Trigger/hammer design should be of such to prevent the pins from walking out while firing.

• Hammer spring should be designed to decrease the time between hammer release and the hammer striking the firing pin from the standard military hammer spring.

• Must be a two-stage trigger (first stage in pull takes up slack and stops, then more weight is applied to overcome this stop until the hammer is released) with at least 65% of the trigger pull weight being applied to the first stage of trigger pull and the remaining weight applied during the second stage that when combined exceeds 4.5 lbs to meet the Civilian Marksmanship Program Competition Rules for Service Rifle #6.1.1.

• Must have a curved trigger bow.

• Must be adjustable for trigger over travel, second stage weight, and second stage travel so it can be tailored to the individual shooter without the need to modify the design by the end users. The use of screws and springs in the design to achieve this is acceptable.

• Must have necessary tools for adjustment provided with each trigger.

Although this order only appears relevant to the Marine Corps Shooting Team, I’m seeing it as an indication of Geissele’s increasing usage within the U.S. Military. Already mentioned is the Geissele trigger in use by the Team, in addition to Geissele handguards in use throughout the SOCCOM community. In fact, if you take a look at the trigger product page, you’ll notice Geissele’s SOPMOD trigger

The Geissele Super Select-Fire (SSF®) Trigger is a select-fire combat trigger that Geissele Automatics developed for the U.S. Special Operations Community.

I take this as an indication of products to come and of Geissele’s continuing success in the industry. The big breakthrough would foreseeably be a large contract that stipulates the companies products being used on something like the M27 or a mass issued DM rifle.

    …..and that’s how the yearly training budget is reduced to 0, infantry companies.

    POGs and their toys. ?

    • Drew Remington

      I’d agree with that. For an organization that takes pride in its warfighting, GCE, and expeditionary roots, the Marine Corps treats its main effort like trash. Between WW1 and now, the Marine Corps has expanded its ranks to create units that don’t actually support the fight, all the while placing less of an emphasis on training and maintaining quality warfighters. When I picture Marine infantry, I see a large Ranger Regiment.

      While replacing M4s with IARs, suppressing carbines and machine guns sounds like it’s going to make Marines more lethal, Marines still have leaders that think “bullets hydroplane out of wet barrels”, resting the magazine on the ground when prone creates stoppages, and the annual rifle qualification actually maintains proficiency. So, I don’t know, maybe a bunch of dudes that shoot 3-gun comps for the Marine Corps, going to different infantry battalions, explaining to guys that their support hand fixed to the magazine isn’t the preferred method of shooting wouldn’t be a bad thing.

      • That is the point of the military shooting team units. They don’t just train and shoot in competitions. The do training for units, and train the trainers clinics.

        • Drew Remington

          On paper, maybe, not in practice. Maybe we worked for different branches but, the only time I’ve ever interacted with a shooting team is when my sniper team competed against them in an F-Class shoot in 29 Palms.

          You’d be hard pressed to find someone that has done a clinic with them. I also don’t think it’s very relevant or applicable to combat shooting. While I do appreciate what it takes to score 470-30x in a service rifle comp, in combat I will not be standing in a shooting jacket, wearing neoprene gloves, or wielding an M1 Garand.

          Basically, the marksmanship units do nothing to improve or develop new TTPs that will enhance the rifleman. The basic shooting fundamentals have not changed since Marines first taught civilians how to shoot pre-ww1. This is apparant when you go the rifle range and see shooters at the 100yard line assuming a wide stance, near-split, while resting their support elbow on the can of grizz wintergreen in their breast pocket.

          • What is described is what I was told by AMU members. I have no idea of what happens in the USMC.

          • USMC03Vet

            All units including infantry have their own marksmanship instructors that go to the school and get qualified to teach(laugh at their unit) and range officer for annual range qualification and unit ran ranges. I have no idea what the marksmanship team does.

          • Risky

            I think the marksmanship team is much like the silent drill team. They’re a competitive and exhibitionist platoon, used to raise the idealistic “stock” of the USMC. The Marines are as much about image as they are warfighting.

          • lookinoutforu

            I’ve fired against the USMC teams. I can assure you, son, they”re not in it for “image”. You need to stop sucking “the bone” and get a life ya’ wannabe, “been there done that” no account “hidey hole diving” coward.

      • Holdfast_II

        ” . . resting the magazine on the ground when prone creates stoppages”

        Ever shoot with the old Thermold plastic mags? Shudder.

        • Drew Remington

          No, I haven’t. I have used issued mags from Hartford, Brownells, Magpul (when units could OPR them pre-2012), and H&K. I’ve also used Lancer polymer magazines. I’ve never had a malfunction from resting my magazine on the ground.

          If a magazine fails because it was rested on the ground, it points to a design flaw, not operator error.

  • Joshua

    They want a 7″ rail on the SR-25?

    That makes no sense at all.

    • Take a look at the solicitation, it specifically asks for an SR-25 adaptor.

    • Jon R

      See my photos above, they are out there in very limited numbers….

  • Renov8

    This is how certain companies and manufacturers get their products in with the military….they help write the specs so that no one else can meet them and then the spec writing company fulfills the order….surprise, surprise? No, its been done this way for some time now.

    • I seriously surprised they had to do this. Typically shooting team purchases are small enough that competitive bidding isn’t required.

  • yvette99

    It is open to the public, and it is a competitive bid. It is, however, a small business set aside. Any small business that can supply the Geissele items can bid. There’s nothing in the RFQ that says the government will only buy directly from Geissele. Your LGS could bid if they wanted to. “Lowest price technically acceptable” will win. There is nothing unusual about an RFQ that specifies an exact COTS item, except for the small quantities that make it hardly worth bidding on — even at Geissele’s MSRP, 10 rails and 66 triggers only add up to about $23K. What is a little surprising is that the Geissele items aren’t included on an existing MAS.

    • More than likely ALG Defense will win the contract. ALG defense is owned by Bill’s wife which makes it a woman owned company which gets a leg up on these contract. On top of that she can buy the rails and triggers from Geissele at prices that he wouldn’t provide to any other vendor.

    • clampdown

      So I guess we’ll see a big ceremony with POTUS handing a $23k chunck of his salary to the USMC soon…?

  • Jim N Jenna SK

    I’ve been using their products for years. I’m glad to see our troops start to realize the potential of these triggers.

    They would be more prevalent if there was a set standard amoung SR-25 / AR10 style receivers.

  • Ken

    The Geissele NM trigger is adjustable, so you can keep it at 4.5lb as it wears to keep it match legal. But yeah, other manufacturers do make CMP legal match triggers.

  • durabo

    Combat is one thing, but DoD range rules require eye protection gear. Edit your photos better.

  • survivor50

    Every AR including the 7.62 versions in my collection wears a Geissele just like this. For a reason…they work just as advertised. I’ll use anything that makes me shoot better right out of the box.
    If your rifle won’t accept their triggers…you may have the wrong rifle…

  • uisconfruzed

    Can’t argue, my Geissele NM trigger’s fantastic.
