OK, I'm not a mechanical engineer, but I know what is good and well thought out and what is not. The GG&G UFIR is NOT good nor well thought out. However, it IS overpriced. Today I got my Tactical & Rescue Equip. Weapon Flashlight Mount ("WFM") for like $29. It IS a marvelous piece of gear at a great price. It blows the doors off my flimsy FUBAR / First Samco FAS-2 light mount for about the same price. The WFM fits on a milspec rail and is solid as an anvil. The knurled knobs have lock washers, work easily, tighten down perfect, and the bolts can be adjusted via hex head. The knobs won't come off if you over loosen them because the hex heads hold them on. Well made impressive piece of gear, that is THE light or laser mount that allows interchangeability, quick and easy toolless removal of your taclight or laser. BTW, the knobs seem much more obnoxious in pics than in person. I actually like them. On top, the folks over there are nice and prompt. Nope, don't know em, nor own stock, nor have I ever done busienss with them. Simply put, these guys make a totally kickass piece of grade A gear....which is probably why they have the military contract. The similarly price First Samco / FUBAR mount is total trash in comparison. Just a helpful review to save ya'll time with failed experiments (like ya'll have done for me so many times!)
