Im looking to replace portions of a AR-15 lower with carbon fiber. What would be the best way of doing this?
There are a number of great ways, I currently use Scotchweld DP420 with a glass bead bond line controller and make sure the aluminum is anodized to mil spec. My results have been great, the only bond that has failed was related to improperly installed hardware.
Checkout this pdf for detailed instructions.

I have also used something similar to ac-130 but off brand… not sure where I got it.
