Q: looking to purchase the BOOTLEG MIL SPEC AR-15 300BLK CAMLOK (M-LOK) PARTIAL UPPER - 8.5. I have an Aero Precision lower I want to install the upper on. Aside from the bolt carrier group and charging handle is this upper "plug and play"? I have a lower parts kit purchased from a local gun shop in Texas. I don't see a gas system listed on this upper.

A: Yes, besides the bolt carrier and charging handle the upper is ready to shoot. The gas system on it is pistol length.
