6mmProShop Flash Hider with Built-In Nano Mini Tracer Unit

"Fits great on the WE Galaxy, just a few mm larger diameter than the upper and does not get in the way of the sights. Light gold finish. Green tracers are well lit.

"Compact and does the job good. BBs (Green) lit up bright.

Battery lasted the whole day.

The silver is a lot brighter than the picture.

"Love this little thing! It really lights up the bbs, especially for how small it is. I wrapped mine in camo form to keep it from getting scratched and dented. No problems so far, Owned it for over two years now

"Fantastic! I was excited about the little xcortech tracers before, but these are even better! No need for the obnoxious little adapter, aesthetically pleasing, and just as functional. 10/10 would buy again.

"Amazing tracer unit, no complaints, fixed my issue with previous tracer shooting off to the left. Just make sure you have a long enough of USB cord

"This tracer rocks. It's the same size as a standard m4 flash hider and as bright as the full size xcortech. The button has a positive click and nice indicator light. It holds a charge and seems to be very energy efficient. I have several tracers and this is my new favorite. This is way better than the acetech lighter which has a finicky power button, a dim power indicator light, shallow threads, and quickly drains power.

"Great little tracer, came much smaller than I expected which is a plus because I didn't want anything too big. Very easy to set up and works very well. Haven't fielded it yet but I have tested it out and it lights the BB's up very well.

Pros:
Very small, not much bigger than a flash hider
Very bright
Easy to use, and unscrewing the shell allows you to charge the tracer without removing it from your gun

Cons:
The tracer threading is negative but the shell threading is positive so whenever you try to screw on the shell tight, it unscrews the tracer. I never can understand why but this seems to be a common occurrence for many mock suppressors, I don't get why they don't just make it all negative threading so you can tighten both at the same time.

"Great tracer unit does it’s job well it lights up your green tracer BBs pretty good, the only problem I had with it was that I was unable to to get the actually tracer unit out of the casing to recharge it, twice. Causing me to break it, twice.

"Was a nice tracer unit until it died.

Received the XT301 Oct 29, 2018. Used for 5 or 6 indoor play sessions, only had to charge three times. However, the third time I charged the battery, when it was full I pulled out the charger and the XT301 made a flash that it had not done before when disconnecting the charger. So I checked the power button to see if it was motion triggering the lights, and the unit would not power on. I plugged the charger back in to see if it would allow the unit to turn on, but it would not show a charging light on the button and pressing the button would still not turn it on. This was Friday Dec 28, 2018, getting ready for the next day of gaming. Requested RMA January 1, 2019.

Pro's: Made BB's bright for its small size. Fit my Ronin6 hand-guard. Comes with -14mm threading on the unit.

Con's: Silver color body. JA10 solder joint from charging PCB(mp180703) to PWR PCB (MPs11p10a) scorched. Paid $79 and got to use for 24 to 28 hours.

2 starts for poor PCB design.
