Who’s the manufacturer?

I have a dedicated 22 LR AR upper with no markings or numbers other than “M1S-22LR”. Does anyone know the manufacturer? Thanks

Did you build it or buy it?

I think it was a kit or just a barrel from model 1 sales.

That upper was manufactured by Model 1 Sales.

Model 1 Sales:

Model 1 Sales is a quality based AR15 / M16 component and accessories provider.

I’ve had one of their 22 uppers on an AR receiver since 2008 and it’s one of my most accurate 22 caliber rifles.

They used to have plenty of magazine ads selling all sorts of AR parts, build kits, complete uppers, etc.

I haven’t seen one of their print ads in quite a while. With the players in the AR world changing so often, I didn’t know they were still around.

Stay safe.
