Midwest Industries SCAR Rail Extension

Midwest Industries, Inc. is getting ready to release a quad-rail extension for the FN SCAR rifle.  The rail is made of 6061 aluminum and uses MIL-STD 1913 rails.  It will be available in both black and flat dark earth.

The extension adds eight ounces to the overall weight of the rifle, but gives the shooter six more inches of bottom rail, plus additional rail space on both sides and on top of the barrel.  The top rail is cut so the front sight on a SCAR can still fold down.

The rail can be removed with the barrel assembly and does not interfere with cleaning, including the removal of the gas piston.

The rail extension adds two (one to each side) quick-detach sockets for slings with push button swivels.

The rail extension is made in the United States and comes with a lifetime warranty.  An introductory price is set at $199.95.

    How is this different from PWS’s version?

    • The PWS rail is not receiver height and does not come in FDE.

      I have the FNH rail on my SCAR 17. It is Receiver height but it uses a clamp to mount the bottom rails together and bolts the sides to the sling mounts.

      Both the PWS and MI bottom rail are uninterrupted.

    not interested.

    Tango Down, where the hell are your SCAR rails!?

    I’d like to see FN come out with a “SCAR 20S” (civi Mk20) with the longer forend standard. The whole point of that short forend on the normal SCARs is specifically for using a “commando”-length barrel in it, so it makes about as much sense for normal buyers as an M203 notch.

      “…so it makes about as much sense for normal buyers as an M203 notch.”

      And yet most AR manufacturers still make their rifles with carbine-length gas systems and 16″ barrels with M203 notches. I’ll never understand why.

      • Anonymoose

        Yeah, but those serve no purpose other than to make said ARs look like the outdated basic M4 paradigm widely used by military and police. Mid- or full-length gas systems and straight heavy barrels are by far the superior choice for ARs. Carbine-length systems cause many more problems with the DI operation, and notched barrels are only good if you have an accessory that needs to be mounted directly to the barrel.

      The government barrel profile was justfied 20 years ago, but it’s silly now. Newer grenade launchers attach using pictinny rails now. There also seems to be some disatisfaction with the government profile not being able to handle heat as well which is why there seems to be a push for the HBAR barrels. Perhaps they should come up with a compromise that’s in between the government profile and the HBAR.

    • Esh325

      I guess it’s subjective. A midlength still works at significantly higher operating pressures than a the rifle length.

      im going to speculate and say it would be fair to anticipate the release of a Mk 20.

      I would drop the money for one…

  • Samopal

    If anything I thought the SCAR could use LESS rails; I’ve always wanted a version with a more traditional handguard, just a top rail, and maybe detachable bottom and sides if you want them.

  • Mike Knox

    Wasn’t there some dingbat who keeps asking for more rails on guns?

    • Esh325

      I’ve only held a SCAR, but the original rail looks like it has a healthy amount of space to work with.
