Still need to address the pistol grip, get the Troy FDE sights and some FDE P-mags. Not crazy with how the rear sight sorta just hangs out there off the rail but it won't lock down unless you run it all the way back.
Overall, I'm very impressed with the Troy rail... very much superior to the OEM Sig unit.
Thanks shadow6492. Its one of my favorite SBRs and I really like the tan for something a little different. Every company seems to have a different color though.... makes it hard to find stuff that matches. All the hues reminds me of my SCAR which is four different colors
DDLES - Looking at your customer's gun; is the MOE grip mod something that you guys do? If so, how much for one in FDE modified for the Sig 556? I am sure I could do it myself, but I'd rather just plug-n-play.
