Archived [ARCHIVED THREAD] - Thick wall upper receivers
Posted: 5/7/2023 11:07:34 AM EDT
Who makes the thickest wall upper receiver?

I've been thinking about milling a slot in the side for a bolt on fixed ejector for my cmmg rdb.

Definitely a billet offering


I have a Guntec billet upper that is super chonky on the sides

I came across a brand  that looked considerably thicker called Sundevil but they seem to be out of business.

Bear Creek Billet side chargers are super thick. Probably close to 1/4” or better wall thickness on those. With lots of real estate on the non-ejection side. If I remember I’ll get a photo.
