I know the flames are coming but I have a question about the total weight of my build when complete. I am building a Spikes 14.5" mid-length pencil barrel with a vortex permed to make it 16". Stock is a CTR and mil-spec LPK. Unloaded, would that get under 6.36 lbs? MOE mid-length forearm. I am guessing just a shade over 6lbs, is that pretty close?
