"Perfect in every sense. Fits any 14mm threaded barrel, and has so many features, there's no reason not to get it if you're looking for a suppressor/tracer unit.

"Ok this is an update on my review
I wish I could give it 4.5 stars but I’ll just give it 5

Pros ————
- it’s light weight
- super handy to have with mid caps
- the tracer unit never misses a round
- easy to use settings
- long battery life
- suppressor part is covered in metal to it’ll last you a while
Cons————
- PEQ unit isn’t best quality plastic and the housing semi-easily broke when I mounted it. But it is a quick release
- PEQ unit can seem fairly large and bulky depending on where you place it ( mainly on PDW/SMG class weapons )
- the little piece you connect to your battery has ABSOLUTELY zero explanation on how to use it but it’s not required to use
- The suppressor part can be kinda long and big

I do really recommend you get this product as it’s super handy!

If you change your spring or air pressure you can see how fast you’re firing ( in meters ) without using a huge Chrono machine.

It can count up or down from a set number. Like my Ronin mags hold 120 rounds- so I have it start at 120 and count down as I fire so I know if I NEED to change mags.

It can do rounds per minute

"I recently just got my package with this tracer until and was excited to use it, and I was not disappointed with it.

It works great so far even tho I haven’t tried it with tracer rounds yet.
It doesnt lag at all, and even dims the screen when you aren’t shooting so save its battery. It looks awesome and fits perfectly.

It does have a plastic body, but the quality seems to be perfect.

I will continue to test it more and update my review later.

"SO FAR, SO GOOD. Went to TAC City Fullerton (Indoor CQB) and put this trio on a G&G Firehawk. Took A LOT of working to get the in-line MOSFET into the buffer tube and had to use a skinnier 7.4 Lipo. Worked great all night but here are more specifics:

TRACER UNIT- works very well even in a fairly lit warehouse (Xcortech Tracers are pretty good anyway so no surprise there)

CHRONOGRAPH/BB COUNTER- still need to figure out how to change the settings (no manual included) so that the FPS and ROF is not in metric. BB count down feature is the one I use in actual play and works awesome. I do a mag change with about 10 BBs left and then push the button on the box to reset the countdown.

BURST CONTROL- this is a pseudo- MOSFET unit since it is an inline unit. It works great but I notice that when the PEQ Box is ON then the burst mode works when switched on to AUTO. When the box is OFF you get normal FULL AUTO... at least for me.

NOTE: Also tried it at home on a VFC Avalon Carbine as well as an Elite Force ARX160 Elite Beretta and they worked too.

CONS: Does NOT come with a manual. Had to Google and YouTube the heck out this to find any information.

"I was going to buy a chrono anyway and decided to spend a little more to get this, definitely would recommend 10/10. You can change the Spd setting from mps to fps, which is nice but i wish you could do the same with ROF from rpm to rps. Also this did not come with a manual but luckily theres one you can download. http://www.xcortech.com.tw/product_cg156965.html _click here

"Chronograph works great, shortcoming (up and down) fantastic and ROF is right on. Low profile, easily soon through iron sights and red dot sight. Man, this thing is awesome. Love it, thanks Evoke.com for the great price.

"If you need a chrono, you might as well buy this for the extra few bucks.
by Shawn S. on 05/19/2017
"Works great. It doesn't have to be completely dark to see the green BB's. I was playing in cqb, where it was dimly lit, and the tracer works great. I haven't tried red bb's yet, but the green ones are great. The chrono seemed to be okay. It was chronoing higher then wear I played. The arena chrono my gun at 335, and this chrono my gun at 350.

"This is one of the best things you can buy for your airsoft gun. There are some things here and there but nothing too serious that you cant figure out.

Out the box there is no manual as to how it works, its functions etc. It does come with a QR code but its a dead link. Had to do some digging on youtube for all its functionalities, to my surprize there were many videos, so you shouldnt have a problem.
Overall the tracer unit is great, lights up every bb my AUG fires at 32rps. As a chronograph the tracer unit is accurate, i did find out that the tracer unit does chrono it 10fps lower, but nothing too serious, just add 10 to whatever you get. The peq unit is relatively easy to use once you see how it works on youtube, you can adjust the brightness of the digital screen, you can adjust how you want to measure the speed of your bbs. It also tells you the battery % you have and you are able to set the unit to stop at a certain percentage of voltage, for ex (11.1v lipo can be set up to stop when it hits 9v) to protect your battery. And last but not least the mosfet, and it pretty much works like it should, burst fire or can be out back to full auto. This is great for enhancing gameplay, by far one of the best investments i have made for airsoft. GET IT.

"I got one of these shortly after they came out and it has been the best purchase I have made other than my AEG. Granted there is a learning curve involved for switching modes or options during a match, because fiddling with settings while having your cover peppered with shots can be a bad thing. lol With a little practice, and having settings adjusted to your preferences, flipping between burst, full auto and then back to burst is a snap. A flick of the finger and your round count comes up and you can turn on the tracers. This little goodie does everything you need and then some.

"This thing is pretty much the swiss army knife of airsoft.

It saves you money by putting many features into a single product and it innovates by making ones of its own original design.

It's light and very applicable to any airsoft player. It's extremely beneficial to any people with low capacity magazine and high capacity boxes.

The chrono seems a bit off but people have, and I also, discovered that it records consistently 10 fps below standard chronographs found on commercial airsoft fields. This, to me, and the fact that the options accessibility mode seems a bit difficult to understand, are the only two issues I have. However, 5 minutes on youtube will have you up to speed on the product due to this confusion leading to the creation of many tutorial videos.

The tracer functions magnificently as well.

All the features function consistently and it's pretty cool watching people notice this cool product and ask what it is.

"This does exactly as it's supposed to. I am not sure how accurate the chronograph is, but it seems accurate enough for my purposes. The tracer works great! The mosfet and BB counter are cool and work just fine, but I don't use them very often. The quick release on the PEQ is really nice to use.

"Great Tracer unit. I bought it when evike first posted it for pre order. This is the best tracer unit I have had. If your considering buying this you will not regret it. The Tan/ Sand/DE color they list it as is close to the Magpul DE which I liked cause it was going on my Magpul PTS Masada.

This really isn't a con...for me but others it may be.(Easy Fix) My Masada has an SMP(HPA) in it. The air from the shot fired will pop off the tip of the tracer unit. I couldn't figure it out until a fellow airsoft player ordered one too who had the same thing happen to him with his HPA Rifle. We both superglued our tips back on and haent had anymore issues. (You could use epoxy too) . We both bought a spare tip from evike later just incase which I would recommend you do the same too if your going to buy one. No trouble after the simple fix.

Buy it!!!

"This is literally the best attachment you can add to ANY AEG you have.
-I have never worried about running out of ammo with the BB counter on, a problem that Mid Cappers like me face often.
-The Chrono and Rounds per Minute counter are spot on, and very useful in seeing how your gun will perform.
-The shot control (burst mode) is probably the coolest thing I've used. I throw it on my scoped AR-57, and it becomes a DMR in an instant. If I need to go CQB. I just double tap one button, and bam, I'm full auto.
-The tracer unit is perfect, and you can even turn it off during day games to prevent battery drainage.
-A bunch of other cool features that come with i!

"I bought one of these a while back and I was very pleased on how it preformed. Out of the box there is no instruction book so I had to use trial and error to figure out what everything did and how it worked. The over all build of the tracer is really good and so is the computer, however the battery chip wire broke but was easily fixed and in working order again and was a tight fit in the stock.
