Ready to push your Umarex TR50 / HDR50 13J (GEN.2) to the next level? This combo set is made for serious users who want a clean install without the headache. The Z-RAM stainless steel bolt comes prepped to receive the included Power-Pin — no need to destroy your original aluminum pin during removal. Just screw it in, lock it down, and you're done.

💡 Why this combo makes sense:
The factory pin is often pressed in and tends to get damaged during removal. Our solution: skip the frustration and start fresh. You save time, effort, and nerves — and gain power.

Nice product. High quality microfiber to go with it.
Size: 16 Fl Oz (Pack of 1)
This product is a nice value for the price. It appears to be a high quality product. As someone just using it recreationally to clean my car every now and then, it seems that it protects very well. It leaves the interior of my car smelling alright and with a nice glossy shine. There is a decent amount in the bottle and its easy to spray on. If you are just using it to wipe dust off the dashboard or something like that, i'm quite sure that the dust will return not too long after you use it. It seems that it protects more for drying out and stains. The microfiber cloths it comes with feel high quality!

Amazing product at a reasonable price
Size: 128 Fl Oz (Pack of 1)
This stuff is incredibly versatile! I use it for anything inside the car to clean it. The best part is it doesn’t leave any sort of greasy residue at all and it wipes off extremely clean. You will not be sorry whatsoever if you purchase this. I’d recommend using a brush in areas that need a little bit more work as this suds up very nice and becomes a good cleaning solution!

The best interior product
Size: 128 Fl Oz (Pack of 1)
I am a Turo host and I buy this in bulk because it is the best interior cleaner! All purpose and works on every surface I’ve come across. It has a very light smell to it, but it’s pleasant and just smells clean.

wow, ahead of the rest, easy to use
Style: Headlight Restore & Repel Kit
wow, i have used a lot of products for my cloudy headlight lens. this was the easiest and the best so far. on a dry clean headlight, open the foil envelope and get the wipe out, wipe the cloudy headlight and it really gets the job done, a yellow stain builds up on the wipe. one wipe for each headlight. wipe dry with microfiber, then spray the sealant and let it sit, just wipe any excess run off on the car body. poof, done! looks good. says it can last up to 18 months. not sure about that, but i will take what i have now. go nu finish, another solid product.
