Wideners has Priv Partizan M855 back on their Website and some 20rd CProduct mags

I have some and haven't shot it but alot of my buddies like it. It runs about $807 per 2000rds delivered.  Any one here that lives around the Princeton Area wants to try some out, IM me.

Palmetto Armory had some ammo and Mags

The Armory had some PMC Bronze 55gr at $349 per 1000rd as of yesterday.

These are a few of the sites that I visit and get ammo in at time to time. Jump on the Federal when it come in, it only last for a few hours or a day before it is gone
