Recently moved back to the southeast part of the metro area from Thornton and was looking for a place to shoot besides Centennial GC. Was looking for new ranges and came across Shoot Indoors new location in Aurora. It's just east of 225 a couple blocks south of Mississippi.
Went in the Saturday after Thanksgiving around 9:00 AM, the place was clean and had no wait. There was two other people shooting while I was there, but seemed to be pretty low key. They recently opened in the last month, and seems like a lot of people aren't aware that they are there. They are getting ready to send some mailers to homes, so it may pick up.
They had some ammo in stock for range purposes but the price was astronomical. If you want more info, you can check them out on their site below.

Seemed like pretty good guys and a good place to shoot.
