Finally getting final components from long back order. Mating my Satern 14.5 Ultralight barrel (with integral flash hider to make it 16.1 inches) with AA upper receiver I noticed a bad "step" on the M4 ramps to barrel extender ramps.
So today I did my version of LRRPF52's "melt job" to get a continuous and smooth set of ramps.
