Marine Corps Systems Command has announced that it has awarded an indefinite-delivery/indefinite-quantity contract to Trijicon Inc, for a total cost of $8,169,996. This contract specifies that the optics will be the Trijicon 4x32mm Rifle Combat Optic (RCO) with the TA31 Bullet Drop Compensator reticle graduated for the trajectory of the M855 round. The award specifies that 28,092 RCOs will be built and completed by September of 2018. This contract further cements the use of the rugged and reliable fixed magnified Trijicon RCOs within the Marines for a number of years to come.

From the contract award description

Trijicon Inc.,* Wixom, Michigan, is being awarded $8,169,996 for delivery order M67854-17-F-1238 under a previously awarded firm-fixed-price, indefinite-delivery/indefinite-quantity contract (M67854-12-D-1000) for 28,092, TA31 rifle combat optics with M855 reticles.  Work will be performed in Wixom, Michigan, and is expected to be completed by Sept. 28, 2018.  Fiscal 2017 operations and maintenance (Marine Corps) funds in the amount of $8,169,996 will be obligated at the time of award and will expire at the end of the current fiscal year. The Marine Corps Systems Command, Quantico, Virginia, is the contracting activity.

Not specified is which weapon system these TA31 RCOs will have reticles for. The Marine Corps is going through a transitional period from having a force armed with M4s and M16A4s, to attempting to arm the entire force with M4 carbines. Unless this RCO contract is a scheduled overhaul of current RCOs that need to be completely replaced, then this contract is most likely purchasing RCOs for M4s to be newly issued within the Fleet Marine Force, Reserves, and recruit training depots. Equipment breaks and needs to be replaced, but we highly doubt that roughly 30,000 of the possibly 100,000-150,000 RCOs currently in service need to be completely replaced through this contract.

  • Major Tom

    But if you listen to the armchair generals we don’t need no stinking magnified optics because allegedly NOBODY ever shoots even 300 meters.

    It appears yet again, they are wrong.

    • Big Daddy

      Everybody has an opinion …….I don’t have an opinion I have knowledge. That knowledge tells me you can never be ready for a specific war you have to be ready to to adjust quickly and have something ready in case. You need to adapt quickly and be aggressive that’s how you win a battle from a street fight to a world war.

      • FarmerB

        Exactly right and completely predictable. If you are prepared, trained and equipped to fight war (a) then why would a potential adversary fight it on your terms? They’ll be looking to fight war (b) unless they’re stupid. Plenty of examples from the last few decades (including the stupid).

    • Gun Fu Guru

      Prior to GWOT, they were mostly correct.

    • Joshua

      No one says that… Like no one.

      PID is a thing and a magnified optic even at 200M plays a huge roll in PID.

      • RealitiCzech

        Aside from the “bring back muh M14 and iron sights!” crowd.

    • Blackhorse

      I haven’t read anyone say “NOBODY ever shoots even 300 meters”.
      Now lots of people say most engagements happen under 300 meters, which is totally different.
      A side note, 4X32 (fixed magnification) is about medium for these types of sights and on the extreme low side for “magnified optics”. Considering they’re called “Rifle Combat Optics” for a reason, and they’re quite good at CQB.
      Real “magnified optics” would be worthless at CQB.
      These aren’t sniper scopes after all.

      In this episode of “Major Tom twists arguments made in order to make himself look right when he arguing something else entirely before….”

  • Gary Kirk
  • FWIW: It isn’t a new contract award; it is merely a new delivery order under an existing contract.

    Here is how to break down the Procurement Instrument Identification Number (PIIN) code for solicitations and awards.

    This is contract M67854-12-D-1000.

    The first six characters give the DOD Activity Address Code (DODAAC) or Unit Identification Code (UIC) for the procurement office. In this case, “M67854” is Marine Corps Systems Command – Quantico. You can also determine the service branch or agency by the prefix to this code. “M” is Marine Corps, “N” is Navy, “FA” is Air Force, and “W” is Army.

    The next two numbers show the Fiscal Year in which the solicitation or award was first posted. “12” indicates Fiscal Year 2012 (October 1, 2011 – September 30, 2012.)

    The next letter indicates the type of solicitation or award. “D” equals an “Indefinite Delivery/Indefinite Quantity” contract. “P” is a purchase order. “C” is a definitive contract.

    The last four characters merely indicate the sequence of the solicitation or award.

    You can also see additional Supplemental PIIN characters to indicate additional modifications or orders,

    The use of a new number M67854-17-F-1238 for the delivery order instead of adding a Supplemental PIIN (M67854-12-D-1000-0014) adds yet another wrinkle. “F” type contracts are defined as “Contracting actions placed with or through other Government departments or agencies, or against contracts placed by such departments or agencies outside the DOD.” Clear as mud right? However, this would seem to indicate that the RCO are actually intended for someone outside the DOD.

  • Dougscamo

    Miles, thanks for the link to the interview of Sgt. Vasselian. A regular guy doing what his country has asked and then some more. Keep it up.

  • Sianmink

    The acog in that second photo looks like it got dragged behind a truck for about 10 miles.

    • Drew Coleman

      Probably still held zero.

      • BeGe1

        Until the 10 cent bottom mounting screws that the armory sergeant won’t allow to be loctited loosened and made its zero worthless anyway.

    • Blackhorse

      If you look closer at the first photo it too shows “rub wear”.
      Considering the second pic is of the left side and that’s the side that usually rubs against the body and gear while on patrol or just carry, this is expected for painted aluminum.
      Otherwise it looks to be in pretty good condition.

      • BeGe1

        Anodized, not painted. The anodizing is actually harder and tougher than the aluminum underneath.

        Those things just get beat to hell though 🙂 You’ve never seen the apex of what equipment abuse really can be until you’ve watched Marines get issued equipment.

        Put a Marine, completely naked, in a padded room. Give him nothing but a bowling ball. Come back 2 hours later. He’ll be bleeding (but not know where from), the bowling ball will be broken in half, one half will be on fire and the other half will be pregnant.

        That’s just how we get things done.

        • Blackhorse

          That’s true and that is still rub wear and not abuse on that Trijicon.

        • Sliced Veggie

          The visual of that. dear god.

  • Curious

    I’m curious about the price per optic they are paying for? If you simply divide the cost of the contract by the amount to be dilivered then it comes out to $290 per optic. Surely this can’t be right? I see it says indefinite quantity, so is the 8 million an initial payment? I’m definitely no expert on military procurement, so I’m interested to know.

    • Flounder

      Dude… That is exactly what I was thinking! Do the marines really get that much of a discount?!?!

      • Beju

        Or, from another perspective, does Trijicon really mark them up an extra ~$1000 for civilian sales?

    • Sliced Veggie

      Remember, they are buying something like a metric crap ton of them. Not a SINGLE ONE like in the civilian market. Also, they have something like 4 levels of disti to get it to you and packaging as well. Plus – its capitalism, everyone needs their cut.

  • BeGe1

    I’m actually a little surprised. Scuttlebutt was that they were gonna start putting dots on the RCO like they have on the SDO in order to standardize reticles.

    Guess that didn’t happen.

    • USMC03Vet

      Never trust the scuttlebutt on the starboard aft of the well deck near the stanchion next to the ladder well where the port hole is.


      • ItsDrazi

        I have no idea what anything you just said means, but it made me laugh!

        • USMC03Vet

          It all common nautical language. Since he used my favorite naval term, scuttlebutt, I felt it appropriate.

  • Kurt Ingalls

    Kind of sucks…..because this will keep the civilian market for ACOGS’ higher than a kitty-cats a##…… 🙁

    • Suppressed

      Giraffe’s @ss works much better, I have to bend down to scratch my cats’ behinds.

  • noob

    ah defense procurment naming.

    Advanced Combat Optical Gunsight -> Rifle Combat Optic -> Enhanced Combat Optical Gunsight -> Improved Combat Optical Gunsight -> Objective Combat Optical Gunsight -> Interim Combat Optical Gunsight (the last staying in service for 120 years)

    • pun&gun

      Now waiting for a fancy night-vision optic called the “Precision Enhanced Nocturnal Interdiction Sight”.

      • noob

        Initial reports say it is hard to use in the mornings.
