Selling my used 16" upper. The upper receiver/BCG were made by TacticalARs.com. The barrel is a FN heavy barrel, the same one from the 249 if I recall correctly. It also has a SilencerCo ASR brake if you want to mount one of their cans on it.
It probably has around 2k rounds through it. I've taken good care of it and it still performs spectacularly. I have no problems hitting targets at 500 yards with it. Selling it for cheap as it's fairly old and has some cosmetic wear and tear.
You can also have the back up sights and fore grip I have on it.
*Does not come with a charging handle.
