There's a lot of rep deployant clasps being sold on the Web as every day, so caution has to be excersized. The older, early rep ones were extremely close to the gen, except for the fact they were missing springs inside 4 pusher holes.
Here's another example of a rep being sold on ebay, most likely catching the premium $$ from a bidder believeing he's getting a gen deployant.
Here's a pic of gen deployments... I sold these recently and they are gen. The pushers are spring loaded but should appear closed when the deployment is fully open. They stick out when the buckle is closed... that's so you can push them in to release the buckle. A tell on most reps is that when a rep deployment is open like in the pic, the pushers leave a gap because of loose/poor spring tension.
