    Default The SIG 556 ZURICH WEDGE

    THE SIG 556 ZURICH WEDGE
    (Patent Pending)

    The SIG 550 Series of rifles is a blending of modern western manufacturing and engineering with the old world simplicity of Kalashnikov's design. The SIG retains the reliability that the AK-47 is famous for, but offers refinement and accuracy standards only seen in Western European weapons.

    That notwithstanding, many of our students and customers have noted a looseness in the upper and lower receivers. While it is known that such tolerances are there to enhance reliability, it would be welcome if there was a way to increase the tightness between the receiver halves without affecting reliability. Some notable designers have postulated that such a uniform tension would increase accuracy.

    That practice is common in the M4 world where worn receivers will the tightened up with polymer or rubber wedges. The only issue with these is that under adverse conditions they have been known to break apart, possibily malfunctioning the weapon. Enter the Zurich Wedge.

    The Zurich Wedge was designed for friends of ours who are members of a European Special Unit using the SIG rifles in a CT role. The Zurich Wedge is manufactured from heat treated spring steel and when installed, will create a uniform tension between upper and lower receivers, providing a rock solid rattle free stability without affecting reliability in any way. The Zurich Wedge is installed under the Pistol Grip screw with the "T" to the rear. When in place, and the rear pivot pin is pressed into place, the receiver halves will be locked up tighter than a swiss safe.

    As far as accuracy enhancement, that has as much to do with the ammo and the shooter, but in our test rifles, both SIG 556Rs, we noted a reduction in group size by .15" in one rifle and .25" in another. If you are running a SIG 556, the Zurich Wedge is an essential addition.

    Hmmmm. I will try to get time to order one. That way I just HAVE to buy the rifle (when I get my Izzy sold and have the available funds) to justify the the purchase. I know,it sounds crazy,but I knew several women in my lifetime who thought just like that! By the purse,then you just HAVE to buy the shoes to go with it,then you just HAVE to buy the coat to match,etc.,etc.,etc.,..........!!!

    If it will work for the 556R and the 522, I'm in for two.

    Cheers,

    I'll take two Zurich Wedges to go please.

    That is a cool piece of gear Gabe...judos...

    Reminds me of what we used to do in the FMF to tighten up an M16A1/A2 upper and lower...we'd cut a Falstaff can into a U shaped shim and bend the tabs on it to keep it from shifting in between the upper and lower...made a rack grade M16 into damn near a varmint gun...

    Ordered one just now. To be honest, the upper/lower receiver play is the only thing i haven't been too thrilled about with my 556. I can't wait to try this out!

    How can you profit from the status quo, instead of complaining about it?
