Parts Purchased....I'm looking for a new round forward assist assembly and a new ejection port door assembly both black in color. They are going in a Rock River Arms Upper.You can email me with what you have, and shipped price, at address below. I'm in the Chattanooga TN area and can do a FTF in that area. Hey Randy this might be something that you'll have, if I can find your number. Thanks for any replies.
