I took these off a recent manufacture NIB Colt 6920. So genuine Colt stuff. Never fired or taken to range. Shipping included with prices.
Delta Ring Ass + barrel nut = $21
A2 pistol grip (just the grip....no screws/washers, etc) = $10
handguard cap = $3
Or take them all for $30
Pic's available on request.
Thanks for looking.
