Wanted: Non restricted AR15 barrel

Looking to purchase a AR15 barrel that’s 18.5 inch. I would prefer one that has two push pin grooves so I can use my A2 front site/gas block. But feel free to let me know what you have. I’m also on the market for the barrel nut, flash suppressor and full handrail system and gas tube sooooo pretty much the whole package. Located in Winnipeg.
