Sig 55x Bayonet Lug

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.
