AIM Glock conversion barrels?

Does anyone have any experience or opinions about the Glock conversion barrels being offered by AIM surplus? I am looking to get a conversion barrel for my 23 and these are significantly cheaper than the Lone Wolf ones.

Dang those are great prices, you almost can't go wrong. If they had a threaded model I'd grab one up. Thanks for sharing anyway. Sorry I can't be more helpful

Wonder who actually makes them, doubt it's AIM. Regardless, at that price you can't go wrong.
