With the current Form 4 approval times exceeding 12 months, I thought it might be helpful to others to share that there are 3 dealers around Indianapolis that have indoor ranges and they allow you to shoot your silencer at their range while you wait the 12 months for ATF approval. Highsmith Guns is located in Greenfield, and they have a really nice indoor range. The only downside is that they only allow pistol calibers on their range, so you if you buy a rifle silencer through them, you wont be able to use it until the stamp comes. Indy Arms Company is in the Broadripple area. Their range is a little older, but supports pistol and rifle silencer conjugal visits. Lastly on the west side is Parabellum Arms in Avon. Their range supports up to 300 Win Mag, and they also have a Silencershop kiosk. In my opinion this is the best of both worlds. You can order from Silencershop, do all your fingerprints at the Kiosk at Parabellum, and then shoot your silencers at their nice indoor range while you wait the year for ATF approval. I hope this helps others looking to purchase silencers or other NFA items.
