It looks like the Gibbz, X Products, Spartan, New Frontier Armory & WMA are all pretty much the same design with a few cosmetic differences.
I like this design but have concerns that the charging handle will not clear an MVB stock which is what I plan to use. Has anyone run this combo before?
Jp Enterprises makes what I am sure is a quality side charging upper but the duel charging handles is probably overkill for my purposes and since I will be shooting it mostly suppressed I would prefer a tighter seal on the back of the upper to prevent gas face.
American Spirit Arms looks to be another option but it looks like a pretty heavy upper and requires modification to the bolt which is something I would prefer to avoid.
All of the other side charging uppers that I have seen have a channel cut in the upper and a handle directly attached to the bolt. I do not think these are a great option for what I am looking for.
What else is out there?
