Hey all, (posting in handgun, as this is a serial numbered item that is considered the firearm) Bought this and shot exactly 20 rounds thru it. Just decided the weight of my upper is doable without this. It's red with fluting and is super accurate!! Pics on my custom Volquartsen: This is an firearm and will require FFL transfer. Price is $199, add $10 shipping to FFL. Thanks!
