I'm getting a tech manual, but the gas tube concerns me. i am going to get a front sight block for guiding me on drifting out the pins on the sight, but i want a little more knowledge on helpful details/hints. Also any comments on a good hidden float tube for my Bushmaster that will fit under or comes with original looking A2 style handguards. Both guns have removeable flash suppressors, btw.
