Do you have other pics? What is the discoloration on the barrel and mag extension?
I'm looking at purchasing a Scattergun Technologies "Standard"-Parkerized. Your price is a bit more appealing. However, I have to admit, I'm not crazy about the finish on your weapon, but am interested in the shotgun itself, the SureFire, and the Aimtech mount. You can keep the cheekrest.
If you have other pics, I'd love to see 'em.
