URX4 install is notoriously difficult, apparently not for Dave!
The lock up on this URX4 install is the best I’ve ever seen outside of using a KAC receiver. Dave got my rail so tight to the receiver, I couldn’t be happier! These guys are THE experts! Your build is in good hands here!

Keymod to MLOK
Fantastic work is all I can say. I had a KAC Mod 2 14.5" with a Keymod rail that needed to be swapped for MLOK. It had a KAC MAMS that another "Gunsmith" pinned and welded . Let's just say it was messy at best. d.wilson was able to remove the messy pin and weld, swap rails, and repin, leaving a beautiful dot of weld. Couldn't ask for better work.

URX 3.1 Install
Absolutely excellent work on my URX 3.1/ upper assembly! Alignment of everything was dead nuts. Highly recommend any of D Wilson's services!
