I have 3 partially stripped Sig P556 lower receivers. Included is the receiver, trigger guard, rear captured pin, rear sling plate adapter, and rear receiver plug. Two of the lowers have factory ambidextrous rear sling plates, and one has a left sided rear sling plate.
These are for those of you that would rather have the original receiver to add an AR-type stock to your Sig 55x.
Asking $300 shipped $250 shipped OBO each. I would also be willing to trade for stripped Classic lowers if interested.
Please email or IM with questions.
