I want to upgrade to a chrome lined barrel. Any recomendations on a new drop in barrel? Also does anyone know if I will have issues with my RRA upper and feed ramps not lining up? I have heard that the rra uppers are not true M4 feed ramps.

Ok a little confused here. Any standard AR-platform barrel? So all the barrels I see availible that have M4 Feed Ramp Barrel Extensions (USGI) will not work? All the ones I am interested in are 16' carbine M4 profile with M4 ramps....
