Peeteee Custom Ultimate Aluminum Shotgun Tracer Unit
(Model: KSG/SGR12 Shotguns)

"This tracer unit costs more than my gas shotgun and it's EXTREMELY WORTH IT, the bbs start fading in long distances, and the system is very simple, all you need to do is charge it, then press that on/off button. This big ol thing makes my shotgun look like a walking dead weapon looking all suppressed and what not. Attaching this unit on any shotgun would be from three grub screws two on the sides, and one on top. But just be careful when actually tighting the grub screws because the mounting adapter will most likely break. My top on bearly made it.

"Obviously a little pricey. But worth every penny. Works great and pcu has great customer svc. They get back to you within hours via email or Instagram. I messaged them on both and they responded to both. The most annoying thing was removing the weird castle nut on the front of the ksg to reveal the threads. Other than that it went on smooth. Shoots bright especially on green gas fps. Was bright when I tapped it at 85 psi dimmed a bit at 110 psi cause of how fast the bbs travel I'm assuming they didn't get as good a glow on the way out. But it was more than enough for me to see. Bottom line tracer is worth the money over the all 3d printed version which I have for my 870 and it shattered from players shooting hot. But even than pcu took care of me. Highly recommended for that extra cqb edge.
