SOFIC – SIG MCX 7.62×39

This is the new MCX 7.62×39 from SIG SAUER. Like the MCX itself, this variant was developed for a government customer. Although they are evaluating it now, you’ll be able to get yours commercially beginning Mid-2017 as a full rifle, upper receiver group or as a barrel, bolt and magazine package. As a matter of fact, those are three components you need (besides ammo) to swap out calibers on the MCX. In case you were wondering, that is a C-products 28 round magazine, although when finally available commercially, a different magazine may be included.

    Don’t they make one that takes AK mags? Does anyone make 7.62×39 AR mags that work?

    • CapnTroy says:

      I wasn’t able to find any that work reliably, including C-products…that’s why I sold my 7.62×39 AR pattern rifle…

      I know that CMMG makes the MK-47 that takes AK mags, but I haven’t fired on yet…

    • Boyes.55 says:

      Yes, the rifle should be built analogous to.the CMMG Mutant Mk.47 that takes Kalashnikov pattern magazines.

      SAN Swissarms (formerly the original swiss SIG, not SIG-Sauer USA) wants to bring the SG55x series to the USA INCLUDING the R models that shoot the M43 cartridge AIUI. Making thus MCX a bit superflous.

      C products mags work fantastic. It is not a mag problem it is a rifle problem. I have a POF in 7.62×39. I only use cproducts magazines, no failures to feed, extract or any other kind of issue in 2k plus rounds of wolf/tula ammo.

    Dah. If only they pushed up the time frame for the trusts to be the faster way.

    Who was the original government customer for the MCX if it has been published? Haven’t seen any releases about big contracts. The biggest order I have heard of was the Met adopting it for ARV, TST and CTSFO along with some 516’s.

  4. Craig says:

    Eww, Franken mags.

  5. Cuvie says:

    I don’t really understand the point of a 7.62×39 AR if it doesn’t take AK mags.

    • John says:

      I might be picking up an MGI modular AR lower just for this, then pick up the MCX upper and ar15 adapter when funds allow.. screw 7.62×39 AR mags

      • James says:

        That’s an excellent Idea! Any of the AR47 type lowers would be as long as they are compatible ( thinking about mag seating depth and bolt carrier clearance).

        Another good use of the AR lower compatibility , with full auto being the other.

        • LastChance says:

          I was thinking something similar. But cheaper. Like the new PSA KS47 lower maybe. Or that 80% lower that hit the market that takes AK mags.

          However, all that said, these mags give you a bolt hold open that AK mags really don’t.
