Ruger AR556 with free-float rail and radiant-style charging handle. Looking for a basic M4-type carbine. I don't want a rail or anything like that. Just a barebones carbine with a delta ring, plastic handguard and whatnot. If you've got a rifle that looks like a 90's- to 00's-era M4/M16, let me know if you want to trade! Would also trade for an 11.5 Colt or similar upper with irons.
