I bought this new as a backup and don’t play near as much as I should. It may have been used once. I selected every option and it came to me prebuilt by Amped Airsoft. It will come with the stand, 2 mid cap mags, battery, and a couple muzzle tips. The build was 1200 or so and I had to wait a couple months to get it.
