I have a like new set of First Samco M33 Handguards that have been taken out of the box, mounted, then removed and put back into box. They were for the wife's rifle and she didn't like the larger size and prefers carbine handguards.
I will sell them for $45 shipped
or trade for / towards
Lower Parts Kit
M4 Stock (don't care about number of positions & don't need buffer or spring)
I can add a few bucks to make up the diff in price of the trade items if needed.
