Great affordable weapon light - Leapers UTG Defender Series Weapon and Handheld Tactical Xenon Flashlight LT-ZL168

I bought two of these, one for my AR and one for my 870. While they are indeed a cheaper brand, and not exactly battle-proven quality, they work great for home defense weapon setups. They aren't super bright and they take the expensive CR123 batteries, but they feel rock solid and do the job. I have mine set up on both weapons without the pressure switch. If you're looking for a good weapon light for a home defense long gun, this will work just fine.
