Just got a new print catalog from Brownell's that is dedicated to AR platform stuff. One interesting thing, which has been aksed about here recently is they list some wood and wood laminate stock/grip/forearm sets; brown laminate, camo laminate, and walnut. Forearm is sort of triangular. They also list a bunch of tools for ARs, including gas port drilling jig, a magazine feed lip bending tool, a gas block setscrew dimpling tool, free-float tube wrench, etc.
Just in case you're interested.
