ar15 - 22 all polymer?

[jwchoi574]

Was thinking about getting a AR15-22 for some plinking and varmint hunting. Was looking at the Chiappa m4-22 at the store the other day and didn't realize the upper and lower are both polymer. Are all AR15-22 polymer? I know I can get a conversion kit for my AR15, but is there a manufacturer that makes one that isn't mostly polymer?

[BANG BANG]

CMMG makes a conversion kit or a dedictated upper which is metal

You'll mainly be looking at purchasing a "real" metal lower and a "real" .22LR upper.

I believe the Colt Umarex is aluminum, but seem to be lower quality than the 15-22. That, and the bolt stop is fake on them.

The CMMG uses real AR parts. Same upper, barrel nut, ect as a standard AR.
