Ordered a stripped Stag lower from my local range (not the best price, but convenient), and now I'm thinking about what to do with it.

When I get it, I think I'll first file a Form 1 and pay the $200 tax to build a SBR. Anyone here know how long processing a Form 1 takes? The SBR will be LLC-owned as I am in Philadelphia. Once I get approval and have the lower engraved with my info, I'll order the other pieces.

I don't think I want to invest in the tools I'd need to assemble an upper, so I'm looking at complete uppers from the likely candidates, at least those that sell uppers with 10.3" barrels, such as CMMG. I doubt that I'll add a suppressor. With .223 supersonic loads it won't do that much good and subsonic .223 is not that useful. Maybe I'll do a later 9mm build to use a suppressor.

This will be a "fun at the range" gun and, an imaginary (I hope), SHTF gun.

There are quite a few options, though, that are hard for a newbie to sort out. I do plan on some sort of red dot optics, but no scope. Lots of choices. Thoughts?
