AR-15 Rifle 20" Collection Inspection Colt/Windham Weaponry/Aero Precision 5-14-2021

I usually take a look at all my firearms about once a year even though I live in the Southwest where there is virtually no humidity or extreme weather other than the heat! Took out my 20" AR rifles today and thought I'd share a little info as I went along. When I was discussing the Colt Match Target concerning the hand guard rotation using a bi-pod I started out saying "bayonet" when I meant to say bi-pod! One of these days I'll get it right!
