Q
micazilla, member, from AZ, United States, asked on June 21, 2020

Are this upper easy to refinish the color or is the color not able to accept another color?

Expert Answer
A
Answered by Armando R., Gear Expert, from IL, United States, on December 22, 2020

This is black polymer and the only way to refinish it would be to coat the entire thing in whatever finish you are trying to finish it in. We cannot guarantee it will properly finish as this is not a metal upper and is predominantly made of polymer.

Q
Doombranger, guest, from SC, United States, asked on April 30, 2020

Is this also compatible for .410 build? Will this upper work with other brand lowers, Sharps Bros maybe?

Expert Answer
A
Answered by Armando R., Gear Expert, from IL, United States, on December 22, 2020

This is a polymer AR15 upper receiver and is technically compatible with any standard AR-15 lower receiver and any standard AR-15 parts. Please be aware that tight fitment cannot be guaranteed as this is polymer and is not mated to whatever lower you are going to mount it too.
