Have new Colt fire control group. .170 size (can be used in current LEO carbines, Match Target and Sporter rifles and carbines). Trigger/spring & hammer/spring assembly.
Need a NEW Colt M4 carry handle. Current black finish only. If it has any damage to the finish, dents or dings, I'm not interested.
If you just bought a new M4 carbine, and prefer more advanced optics to iron sights, maybe you'd like some replacement parts you DO/WILL need. Email for pics and, likewise, send your pics. Thanks.
