It's an L.A.R. lower and parts kit, (who makes stuff for bushmaster), flip up buis, 4 rail fore end, throw lever mount, chrome lined barrel with magpul MIAD and trigger guard, tac light with pressure switch. The only down side is the optic is a tacpoint not an aimpoint.
Basically, what you see is what you get. This is a really nice rifle, it's got a max of 500 rounds down the tube, selling it because I'd rather have like 3 ARs and tons of ammo then a lot of ARs that I never shoot.
Never even mounted the launcher, bottom of rail removes to accomodate it.
$950 gets it to you. I'll be out of town thursday through sunday.
