polymer made uppers receivers

[100]

Who makes polymer uppers besides Bushamster and ATI ? I have a TN Arms lower that I would like to use with a 22 conversion.

Robar had a nice polymer upper, but I don't know if they sold it as a standalone item or just complete uppers.

Check their website.

Why not just get a poverty pony or PSA if price is a concern. They will be better than any poly upper. The only poly receiver I would consider using would be cav arms lower if I was trying to go light weight, but still would probably go with 7075. If you want light weight they have options without FA and dust cover
