Awseome rifle, Im building a mk12 soon, and im caught between a mod1 and mod0
How exactly did you modify the handguard to have a rail nearer to the magazine? did you have to drill and tap the holes, or were they already there?
Also, how does the flashider unscrew to expose the threads? does the collar remove like the real Ops flashider, or is it one piece?
again, nice rifle
