Gen 1 Rattler upper in 556. I shot this around 500-800 rounds. I bought it as an upper only. I had it on a Virtus lower which I have already sold. I will include the adapter for Ar lowers if needed. I am mostly after cash but I will look at trades if it's in my favor. My wife is pregnant with our first and I'm trying to build up and emergency fund. Just in case. Call or text me for pictures at (765) 318-48sixthree. Thank you for your time and God bless you.
