SIG SAUER - Never Settle

MDM – CSASS Goes M-Lok

The Compact Semi-Automatic Sniper System rifle will transition from the HKey Mod attachment system used on H&K’s solicitation winning submission to the M-Lok attachment from Magpul.  In this case, it’s a Geissele Rail (and optics mount).

    First mlok rail officially used by any military?

    Keymod is a sucking chest wound with no medic in sight…

  3. D says:

    Happy to see that it’s wearing a Giessele rail. Hope that becomes the rail for the CSASS.

    Those offset fold down irons tho…

    I can’t help but wonder how HK feels about this. I’m not involved in DoD purchasing or know if this is normal, but I’m curious if HK feels slighted by having to source the rail from a third party instead of re-tool their pre-existing rail to be M-LOK. Maybe some end users are just big fans of Geiselle. Pretty interesting.

    • BGB says:

      Rumor has that certain special operation “Unit” required their HK416 came with the Geissele rail directly from HK factory. If that is true. Then for HK it is just another Geissele rail for another DoD customer, no big deal. I wonder about the cost and weight. Geissele rail is tough, however is neither light nor cheap. Is this change cause a rise in price and weight?

      This is quite common in the defense contracting world.

      You keep the customer satisfied.

    Didn’t see that coming…

    And the OSS suppressor?

  8. YOGI says:

    I needz this handguard in my laif :/

  9. Bobby Davro says:

    With open source availability of mloc and so many high quality producers this just make sense

  10. Diddler says:

    This will be SO SO SO heavy. I love HK and Geissele, and own a bunch of their stuff, but boy that makes me tired to look at it.

    Time to go lift weights to prep for when I get issued that beast.

  11. SecondGradeMath says:

    It still meets the CSASS weight requirement Diddler

    • Diddler says:

      Never said it didn’t. HKs awesome 556 carbine with the long Geissele rail is insanely heavy, like heavier than a M110K2.

      I’m sure the gun is great (and meets requirements) as pictured. Doesn’t make it a lightweight.

    Good news is if you gonbongo on ammo it makes an excellent club

  13. Nick says:

    Really can’t express how happy I am to see HK dickmod slipping… granted I was on the losing side of keymod/mlok but with HKs mod attachment everyone loses

  14. AbnMedOps says:

    I’m not a machinist or a procurement guy or anything, but…why the heck are BOTH these competing “standards”, Key-mod and M-Lok, apparently designed in INCH specifications, not in metric?? I understand that a bunch of the US civilian firearms industry is saddled with 100 years old production equipment and designs, but NOT the rest of the world, which has been metric since forever.

    • Jay N says:

      Because ‘Merica!!!

    • chris says:

      a large portion of american engineering is done in inches because that is the legacy of the aerospace industry, which is not changing anytime soon because of the sums of money invested in designs, drawings, and tooling scaled in inches. Also, decimal inches work just as well as the metric system. I often see people express your sentiment when comparing fractional inches vs. metric, which is a debate for carpenters. I work in aerspace and measure things in 10ths, 100ths, and thousanths, it makes sense to me.

      • Chand says:

        No it doesn’t make sense. Do we use “decainches”, “hectoinches”, or “kiloinches”?

        The factor of 10 conversion and an appropriate prefix makes the system much more convenient and communicable to others. That, and we’d probably have more appealing products for export.

    • bloke_from_ohio says:

      I shall paraphrase a far better author than myself.

      The metric system is used by countries not saddled with the burden of having walked on the moon.

        Remind us again who smashed a probe into Mars because they could not into international standards?
