Seekins is good to goTo add to what was just shared I was building my SBR and wanted to hide my silencer inside the forward grip. The silencer Outside Diameter was 1.5" and it was tough to find a "fancy" guard to hide most of the long silencer. Long story short, I called a few of the manufacturers of the pieces I wanted but it had to be RAW, it was already headed for some Bazooka Green makeup. I called Seekins and a young lady answered the phone in what sounded like a small shop. I told her what I was looking for and she yelled across the room to pull one of the hand guards off the line it doesn't need to be finished for this guy. She asked for my credit card info and address and it was on my doorstep less than a week later.
True story, I still have that hand guard as Geisselle tempted me too much.
