Good morning, just wandering if you still have the weapon ? If you do, my two sons and i are interested . Our boys are both federal police officers . Every now and then we build a rifle or two to sell or play with, my best friend is a FFL dealer. Anyway we just put together , with all new ROCK RIVER parts, an M4. It has 16 in. M4 barrel , bayonet lug, A2 flash hider, it is a flat top. BAD LOOKING WEAPON . If your interested email me at firstname.lastname@example.org . Now where up here in wild and wonderful West Virginia . So let us know . Being that we both are so new to this sight , a little talk on the phone would probably be in order.
