Fit and finish excellent. - Strike Industries MEGAFINS XL Rail with KeyMod

Installation was a very minor challenge getting timing right but didn't take more than 20 minutes. I searched for but couldn't find information as to using the set screws properly as instructions seemed to indicate installing them after securing the guard to the barrel nut however I used them first to carefully align the Picatinny rails before installing the eight screws. I have a 7 and 10 inch version for a dual upper pistol build and this method provided absolute precision for rail alignment. Very pleased and will probably be using these handguards for all future builds.
