Sold/Expired Sig AR Upper for Trade

[Bulldog25]

Looking to trade my Sig AR Upper with front sight post for an Upper with a low profile gas block.
Upper doesn't have a carry handle it has the flat top rail and has a magpul handguard.
Also the upper has never had a round fired through it.

If all you want is a low profile gas block, that is an easy change. If you want to change it and need help let me know.
