Can I have an barrel already pineed with a front sight base milled for a PRE set screw front sight gas block?
Sounds stupid? Yes! I don’t want to have to go out and by a new stripped barrel.

You do not need to mill a flat. You can simply dimple the spot where the set screw will contact the barrel assuming there is no interference from the existing pin holes
Rainier Arms even sells a jig to make the dimpling easy.
Blame any misspellings on Tapatalk
Yep Ive got that jig. It works great and costs about $40.
What all GBs it fits I don’t know. It states on Rainer’s website it will fit the Vltor and PRI models. I can vouch for the Vltor model that the tool works great.

Can not use on PRI front sight bade gas block. Think more like WOA SPR barrel
Are you referring to this GB/sight?
If you can work around the previously pinned area and if the holes in the GB match up with the dimpling screws on the jig (may want to call Rainier and find out) I would think it would work fine.
Unless I am an idiot and completely missing something and I think I might be.

Those are 8-32 setscrews.
The existing pin cuts in your barrel will not leave a flat pad for the set screws to land on after the crescent cuts are made.
You can just do a single detent though and use that to hold the sight in place while some sleeve retaining loctite cures.
Many highpower front sight bases are held on with nothing but loctite sleeve retaining compound, no setscrews at all!
The OP is asking about these type of cuts:
Ah. Ok I gotcha. Much appreciated Randall.

Ok - so I can still have the flats milled on the barrel even though it had been pinned?
You can have the flats milled, but the set screws are not likely to bite on the flats as the 8-32 set screws are of a similar size to the taper pins that were originally on your barrel.
The better solution would be to get an un-drilled PRI front sight and have it pinned to your barrel with oversized pins that would cut out past the existing pin cuts that your barrel has.
OK - I think I’m going to go with the “crossbolt” model and try to find someone to put a pin through it to keep it in place. Link: http://www.precisionreflex.com/Detail.aspx?PROD=186686&CAT=4292
Thanks again for all the input
