Hello, I am new to the forum, this is my first post. I am looking for a long throw flashlight to mount on both my AK 47 and PTR 91, for hunting. My experience with quality lights is pretty much nil, and I am concerned with the ability of the light to hold up to recoil. The AK doesn't concern me as much, since the recoil is not much more than an AR 15's, however I feel the .308 PTR could potentially cause problems. I have read some discussions about the Fenix TK32 and some of the ArmyTek models and like what these lights seem to offer, but am wondering if the step up in caliber from 5.56 to .308 would make a difference in the light's ability to function. Any info/experiences would be appreciated!
