They are a very bright and effective forend light at an attractive price point. With that said, there are a few things that I don’t like about them.
I find them to be “odd” looking, and believe that they lack the refined appearance of a Surefire forend light. In spite of this, they handle well and feel and function relatively normally in your hand.
I don’t like that they are constructed from two separate “halves”, which are held together by phillips screws. It gives the forend a look of cheapness, although they do seem to be rigid enough in use. By contrast, a Surefire forend light body is formed as a single piece, just like a factory Remington 870 forend.
The TL Racker lacks an “alignment post”, which is a feature that prevents unwanted axial rotation of the forend. The only thing that prevents the TL Racker from rotating quite a few degrees around your shotgun’s magazine tube is the torque that you applied to the forend nut. There is a sizable internal gap between the TL Racker and the sides of your 870’s action bars, so the lack of a tight fit there won’t prevent forend rotation either. The factory Remington 870 synthetic forend has this “alignment post”, which engages a notch in the forend slide assembly, between the action bars. Even if the factory forend isn’t reefed down, or if it becomes somewhat loose, it won’t rotate.
The contact surface on the TL Racker which the forend nut bears against is flat, while the corresponding surface on both the forend nut and the factory Remington 870 forend is angled. A forend nut with an angled surface, tightened against the TL Racker’s flat surface will not have ideal surface contact, and may be subject to loosening from use. Due to this poor surface contact, you might want to put some blue Loctite on the forend nut when using a TL Racker.
Some people have complained about the switch pads, because they make an audible “click” sound when they are pressed. This may or may not be a “real world” issue. The blinding, 1,000 lumen light which immediately follows that “click” will be a lot more of an attention-getter, to be sure.
Some people have boogered up the notch in the (plastic) battery cap when they tightened it down with a tool, which seems like user error to me. I tightened my battery cap with my fingers, which works fine for me.
The TL Racker is a good option for those looking to affordability add a light to their Remington or Mossberg shotgun. They aren’t perfect, but they get the job done. They have earned a credible track record with law enforcement, so they’re obviously “tough enough”.
