870 Express started with a 20" barrel and factory sights that I traded for Model 36 S&W. Hey, the guy just had to have it!
I replaced the front sight with an XS white stripe and filled in the dovetail from the original rear sight with epoxy. Added an XS ghost ring on the receiver. After bead blasting, the external metal parts finished with Brownells Baking Laquer in earth brown, with the innards finished with Brownells moly-teflon in the same color. Lengthened the forcing cone and cut the stock off about an inch for improved LOP. Added the SureFire forend, SideSaddle, Tac-Star mag extension. Single-point sling is from the Wilderness.
