Just visited Boston Gun Range last week.
Wouldn't go back if you paid me. My impressions:
The problem with a place that rents guns to anyone who walks in the door, is well, they rent guns to anyone who walks in the door. I'm not being a gun-snob here.
There were some boys and girls (and I do mean kids (yes, no doubt of age though) who were downright scary in there. The "range masters", who kept rotating, seemed more interested in focussing on the hotties who were in there than keeping an eye on everything. As I came in and out several times there was some scary muzzle sweeping by a few yahoos who had rented some big iron. I sadi something twice and both times was given the "Who the EFF are you look?". I left after the second time. There just total lack discipline in there. Don't get me wrong, I like to have a good time when I shoot with buddies. laugh it up, hoot and holler when someone breaks out a new toy that makes good noises. But a hot range ain't recess.
I brought my own guns, but in looking over the rental offerings I felt they appeared ill-kept. Maybe they were just old and had worn finishes and I was judging books by their covers. There were some half decent looking guns in the case, but not many. This is not a place to go to try out the latest hardware before you make a purchase, unless you're looking for a 10 year old Beretta or Glock.
The counter employees were friendly enough, although the guy who seemed to be the manager left a very bad taste in my mouth. This, perhaps, was just a personal thing and entirely subjective. But if you partially judge a business by the help, well... you know.
Yes, it was expensive, but I knew that going in. No complaints there. The place has almost no stock, so don't go there thinking its a gun shop. It isn't. It's semi-clean, but run down looking all around.
I'll be joining a local club soon so this kind of place won't be a concern.
