A Few Words from our Clients

A friend and I visited the range for the first time yesterday, and you know as soon as you walk in the door that this is a quality operation. The place was immaculate, the staff knowledgeable and friendly, and there was a great selection of firearms and accessories. We had a great time shooting on the well-lit range with excellent ventilation. The value for the dollar is great, and it’s is without a doubt the finest range and retail operation of its kind I’ve ever visited. There’s no doubt this will be our go-to range from now on!

– Sandra Gallardo

Took my LTC class with instructor Ron Benton. I honestly thought it would be a boring class, falling asleep, etc. Boy, was I wrong! Very informative, laid back, cracking jokes. I really enjoyed myself. I will recommend everyone I know to come take his class because I know they will have a great experience as I did. Thank you Ron.

– Joshua Rice

Buck & Doe’s is such a great to learn gun safety. The staff is so helpful on any level your at. Their instructors in my opinion are the best and I look forward to learning more. If you have any interest in practicing your second amendment right, this is the place to to start or continue.

– Curtis Kilgore

Disappointed I didn’t come here sooner! Great place and experience. Friendly and knowledgeable staff. Ron Benton was my instructor and he was professional, courtesy, knowledgeable and friendly. Atmosphere wasn’t super uptight or stiff but safety was addressed first and foremost. Plan on coming back real soon!

– Cuong Nguyen

Great spot to get the supplies to exercise your 2nd Amendment right and do a little shopping! Nice selection of smoker and cast iron supplies. Huge supply of holsters made locally. Gun range was clean and solid with reasonable rates.
