I'm looking to do a clone of the Survivalist rifle build from FO:NV. I can not seem to find a mid length gas system that has the a2 fsb. Does anyone know of a place that makes a FSB that is .936? DPMS did but it has been discontinued. Am I just going to have to get the standard FSB machines down?

Looks like you're up shit creek.

They make a high and a low model.  Slap on your choice of BUIS, and call it a day.  

Finding someone to 'remake' that DPMS is a non-starter.  Unless you want to spend thousands in machine and man labor hours to do it.

Thank you. I was going to see if they could machine the opening that goes around the barrel to .936 not make one from scratch.

This has been discussed several times over the years and IIRC there is not enough meat in a .625 or .750 A2 FSB to ream out to .936, and again IIRC, not even to .875.

There isn't enough "meat" on a standard front sight base to do that, not even close.
