West 38th Avenue between Sheridan Boulevard and Harlan. Easy to get to.
FFL, 25yds, five lanes, up to .30-06, well-kept, ventilation good, fair lighting over the benches, fair amount of parking, zero snottiness from the staff.
Zero, null, nada, 0.00. Very helpful in all matters. Good stock of rental and consignment guns. Good training classroom.
Good on ordering stuff for you, too.
Recommend double hearing protection since it's fairly small and the echoes are bad if someone's firing a Laudenboomeröhrgebrechenergewehr or a magnum pistol. Tell the ladies to take off their earrings and sweep their hair up for a better seal with the muffs.
Also,
http://www.yelp.com/biz/trigger-time-gun-club-longmont, is excellent, cutting-edge up to date facilities a short trip up I-25 to Longmont. Membership required and limited, but you can go on a guest pass. IDed sign-in required.
Read the on-line rules first. No exposed firearms in the parking lot, and things like that.
100-yard indoor rifle range, shooting from bench only, to avoid "missing" the backstops, standing allowed on pistol ranges. Lanes can be reserved on-line for members.
Excellent selection of rental and new-for-sale guns. First time I ever handled a Chiappa Rhino was there.
Both sons are members and I shoot up there on their guest passes.
