TC59 tailcap

I use these little flashlights for work and I bought this several times to replace nonworking switches. This model has never failed me yet.

Very nicely made. The finish is completely matte, so it looks great on my G2 LED.Pros: High quality material and construction. Threads are smooth, button has a strong click with reasonable travel and pressure. You can turn the cap 1/8 and it will disable the switch for safety.Cons: This will add nearly 1/2" to the overall length of the flashlight so it may not fit as nicely in your current holster or case. The rubber switch cover sticks out a bit more than the cover on the OEM tailcap. I can envision this breaking down and tearing within six months to a year of heavy use.

Great tailcap

I haven't come across any issues yet. The end-cap is threaded properly and fits the Surefire 6P (1" diameter tube) thread pitch, as well as clones of it. I currently have it on an old Solar Force L2 flashlight body that I bought several year ago. The click switch is crisp, not too spongy before it clicks. The light activates, so it is doing it's job. Whether or not it will last the 20 years that my Surefire click-on/off tail-caps have, is anybody's guess, but I'm not expecting it to. For the price it is machined well, has an excellent finish and very good texturing. So, in the looks department it's a winner. I've only had it for a couple of months on a spare flashlight. We'll see how long it lasts.

The media could not be loaded. This is exactly what I wanted for my old SureFire Z2X Combat Light.

Works great on my surefire 6PX. I didn't realize the model I bought had the tail cap that you twist to turn on. Pretty stupid design actually. the button on the tail cap didn't click on. it was more momentary on only. This tail cap made my light functional and now it's fit to be weapon-mounted.

Bought as a a replacement for my Surefire C2. Does not work all the time. Have to tap the flashlight to work after turning on the tail cap. For the price it was worth a try.

I use this on my Malkoff LED converted Surefire G2 and with this tailcap it’s become my favorite flashlight to actually carry and use out of the many flashlights I own, many of which are high end and custom ones. It adds a bit of length over stock dimensions but the checkering helps you grip the light much better. The click is just a hair “mushy” and the quality isn’t super high but it’s a good design and the quality is decent. You can half press for momentary on. I plan to buy at least one more. These are made in China.
