Great look installation could use some updating - Obsidian Arms S-Pattern Handguard, M-LOK

I purchased this 7.5" handguard for a AR pistol build. The 'S' cuts are good looking. The finish is good quality, however this add-on came with zero instructions. Timing the barrel nut with the gas tube wasnt a pain, but there are plenty of other after market products with wrench flats that don't require timing.
