Streamlight TLR-4 Problem

[TheExiled]

I bought a TLR4 off of Amazon (thru shop 2A of course) and it is great, nice and bright and installed tight.

However the windage adjustment for the laser will not move. It came with an allen to adjust it but it is so stiff that it will just strip.

I dont want to keep forcing it and strip the adjustment screw out, so any suggestions before I try and get another one?

Just an update in case anyone searches and is wondering about the TLR-4.. I returned it to Amazon after reading some of the new reviews since I purchased mine, where many others are having the same issue. Amazon is no longer selling it through them, just other vendors which says something about it. Im going to contact Streamlight before I make a decision on getting another/something else
