    Hm... a Swiss saw back bayonet would look awesome. The Swiss have three models to choose from.

    A lot of the bayo lug adapters out there for sale are to attach a NATO bayonet,which is a lot cheaper and easier to get than a Swiss one.

    Robert's SIG Bayonet lug ad on Sturm clearly states......" allows the attachment of most US / NATO (M7, M9 or M11) bayonets. "

    Bayonet Lugs are not supplied on Sig USA produced rifles. They do however provide a mounting point / round hole type of socket at the bottom of the gas block to attach the lug. The MFI SIG 550/1/2 Bayonet Lug slips into this hole and is held in place by a drive pin / roll pin (included with every lug) that is easy to install. This allows the attachment of most US / NATO (M7, M9 or M11) bayonets.

    SPECIAL NOTE: SIG 556 Rifles & 556 Pistols with Quad Rail Hand Guards that use this same hole / socket as a hanger point will NOT be able to mount this product.

    Retail Price: $26.00

    The "Swiss" bayonets are Not US / NATO "Type" ......This is the correct lug for Swiss Bayonets

    "Tulta munille!"

    "Terror is not a new weapon. Throughout history it has been used by those who could not prevail, either by persuasion or example. But inevitably they fail, either because men are not afraid to die for a life worth living, or because the terrorists themselves came to realize that free men cannot be frightened by threats, and that aggression would meet its own response. And it is in the light of that history that every nation today should know, be he friend or foe, that the United States has both the will and the weapons to join free men in standing up to their responsibilities."
    John F. Kennedy
