I'm replacing the FSB base on an AR and managed to slightly nick the barrel. Duct tape just couldn't hold me back from
.
Q1) Would anyone advise to whether or not I need to gun blue or? It's a very small nick (1/16)? Do I need to treat it?
Q2) I've got tritium front site and wonder about how a red dot (T1,etc) would affect site picture. It's an A1 carry handle upper.
Thanks for any advice and be well. Surv.
