Same here...must've ben a supply chain problem like everything else. A screw fell out of a server and they couldn't get a replacement.
Auto parts, anyone?
Agency makes good parts. I recently bought one of their magwells for my Glock 19 gen 4. I kept pinching my hand between the magazine and the bottom of the grip during speed reloads. So I added their magwell and the problem went completely away. It kept me from having to move up to a 17 grip.
Thanks! I like RailScales...I have them on a lot of my guns. The PVD is just a smoother process that has been shown to reduce friction and wear. It's smoother than my M1 and M2 so I imagine it has improved the factory M4 stroke.
