Who keeps them in stock - I want to go look/ touch before I buy ?

Weg’s is a good place

There really aren’t many.

If you have an aero lower, check out ballistic advantage, they make barrels for aero and sell their own uppers made by Aero.

I ordered all Wilson Combat parts the last time. And assembled it myself. It turned out exactly how I had hoped for. Those are all really nice parts. Made in Arkansas U.S.A.

^^^^ me too, I assembled all the parts in an Aero upper and I've been very pleased.

Last time I "built" an AR, I priced out a wilson barrel, and various components, and it was just about the same price to just order a complete Wilson Upper. So, I built a lower and ordered a complete upper.

There's never been an upper that is perfect for me. I learned years ago, to just buy the parts. Instead of buying an upper that's "close", and then swapping out parts that I didn't want. That loses money.

So, if the parts or an upper are "just about the same price" I'm money ahead, and got 100% what I want.

I guess I was lucky. Wilson had a pre-made upper with exactly what I wanted.

That’s where I buy suppressors , I should have thought of that

Bauer Precision is awesome. Have never been in person, but ordered online and the service is great.

They have some really nice Geiselle uppers around 1400ish and a few SOLGW ones for 800 or so. If you wanted to save some more, aim surplus has a sale on the Aeros right now for $500ish and Dirty Bird has some contract overrun Daniel Defense 11.5s for $700.
