Anyone know of a good source that is relatively cheap?  Need several models.  Thanks

I've never seen a site that was "cheap" per se. Most of the prices seem to be fairly universal across the board for the brand.

okay, who then would have the largest variety and be a good sourec for them?

Are you talking about the blue synthetic training guns?

I saw a blue M249 in the last Ranger Joe's catalog being used as a model for a sling. Where can I get one of those?

Most LEO supply catalogs have them(the blue plastic training weapons)(they make simulated radios, mags, etc as well), so do Brownells.  But the vendors that have several styles are very expensive; and the vendors we can use a  dealer/dept rate have very few styles.    We may be SOL and just have to order them for full retail from Rings.

The catch is everyone has a Glock 22 blue gun, but few have the M4 with FF and flattop so we can put forward grips, lights, and optics on them just like the real weapon; and still train with NO fear of any negligent act occurring.  It also keeps everyone's fright factor down in the neighborhood when you do drills or during a class.
