Xcortech X3300W Advanced BB Control System Computer Chronograph / Tracer / Burst Control Unit (Color: Dark Earth)

"Howdy, if you're on the fence about getting one of these you definitely should just do it already. Not only are you getting a highly reliable tracer unit / mock silencer but programmable MOSFET (I haven't played with it much) and of course the brains (PEQ box). I can't explain how happy this makes me... I like to use it with my FN2000 because it has an adjustable spring guide (adjustable fps) and this helps ensure I'm using a proper velocity for the battlefield.

Aside from the velocity verification this brilliant piece of kit also counts shots fired (count up or down), rate of fire (ROF), and provide you with battery voltage information! If you use Li-Po batteries this thing is a Godsend!

I've tried to put it through its paces and I've only had one issue with it. When the batteries started getting low the wireless communication was spotty at best, but slapped some new AAA's in it and good to go! I'm actually thinking about getting one for all my guns... then again do I really need 12 of these...?

pros
Awesome!
tracer is reliable at high-ish rof
chrono is fairly accurate
MOSFET
fairly simple to use and operate

cons
tracer and peq use different batteries (peq= 2AA tracer= 4AAA)
Didn't come with manual
doesn't cook you breakfast

"This product is awesome. I'm guessing I got a version 2 because mine has a stop function. So when your counter hits zero it stops your gun.

"What can I say about this item besides it is one of the coolest things I've ever put on my SAW. There is no manual included but here is the link to the online manual as it is hard to find https://986c92fb7300c49e3eae6eafdf792df9bd834466.googledrive-

pros:
Great Tracer
Accurate Chrono
BB count works perfect
Durable
Auto Off for using LiPo batteries.

Cons-
ROF takes many bbs to measure
Confusing without the manual
Not owning one of these.

Overall I love this thing. Finding and using this manual is a must, otherwise it is very confusing.

"so far an amazing system and (once you figure out all the settings) its an amazing system to add to any gun

Pros:
-ready to go out of the box (- batteries)
-plastic seems to hold nicely, have played a few games and the box has taken a few hits from tree limbs with only very minor dings
battery life so far has held up, have not needed to change them as of yet
-all the features are fairly accurate with in two to three units of what ever you are measuring

Cons:
-there are no instructions in the box so youtube searching is a must
-set up is confusing at first but then really simple once all the modes are figured out

overall something of a must for any high tech airsofter, (tbh very comparable to the ascu system) very simply to install

"This is thing is simply put - Awesome.
It does everything as advertised and works great!

pros-
1 tracer works very well
2 chrono is accurate
3 sleek low profile design PEQ box
4 bbs count (Up and Down) is not a cheap gimmick, it works surprisingly perfect

cons-
1 the ROF is not in rps but in rpm (not a big issue though)
2 the ROF doesn't work all the time (at least for me it didnt)
3 it didn't come with any instructions, Seriously it can be confusing without them with so many options.

other thoughts-
This thing is AMAZING. Im using mine on a G&P Magpul PTS VPR GBBr and fill my mags with 31 bbs for a awesome milsim experience. That being said I havent gotten around to testing it on a AEG to play with the Mosfet or check the voltage with the unit but judging on how well everything else works Id still highly recommend it for both AEGs and GBBrs.
Sidenote - Depending on your preference this can be a pro or a con, the PEQ box uses 2 AAs and the tracer its self uses 4 AAAs instead of internal batteries.

"Wow this thing is amazing. Pop the batteries in the tracer unit and peq box and your ready to go. The entire system comes in a small box well packed. Although the package does not come with a manual on how to program the mosphet or what the different words mean when you turn the dial to the set setting which let's you program it. ( evike can you find a manual for this it would really help). I give this 5/5 because of the versatility of the entire system. Can't wait to use this at all the different fields I go to and mess with the refs during chrono.

"Bought this system to utilize the round count-down feature on my gas blow back, this product works exactly as advertised and I could not be happier with the results. Given I use this on my GBB, any feature that relies on the SCU is out of the picture, but functions like the chronograph, RoF, round count UP/DOWN, and tracer control work just fine.

As most others are saying, I can also confirm that the build of the PEQ is plastic. Upon receiving my unit there was some loose pieces of plastic that broke off inside of the unit and were shaking around. I was able to remove them and there does not appear to be any impact to function, but it is worth nothing that this system is FRAGILE. A descent whack against a tree or a wall would almost certainly put this system out of service.

"Its a great unit for electric guns. It has issues using this on a GBBR.

"everything works great but the peq module is weak. it just broke on me after it shook lose and fell onto the floor. you may want to make your own casing or reinforce the plastic some how so this doesnt happen. overall its a great product it just needs some fixes to it

"Works super well and I love it. but dang it sucks to setup. There should be directions on paper explaining how to connect and make it function properly.

"This thing is very good. A few gripes I have is that the suppressor part is too fat to fit on some guns with a 'recessed' barrel (handguard goes past the barrel). Notable example on my Krytac CRB it won't screw all the way down without an extension piece which results in wobbling. This caused the BBs to hit the inside and completely destroy my accuracy and FPS. After getting an extension piece however it worked quite well. The ammo counter works nicely and is very useful since I run mid caps. I didn't have any of the issues mentioned in other reviews so far. Nobody shot out the box, but I also have an additional sight protector in front of the screen. The "cheap plastic" body has received a few direct hits and is still working just fine. The only issue I had with breaking is the tip on the suppressor unit is made out of VERY thin plastic for some reason. It came with spares and BOTH got shot out. The unit still works just fine but it no longer has the cap on the end. IMO that part should be metal since it points head on towards enemy players.

Pros:
-Lots of functions (ROF, FPS, ammo counter, burst fire, LiPO saver)
-Nice form factor, computer unit is small and slim
-Looks good
-Included spare 'plugs' for suppressor tip
-Included MOSFET can enable burst fire, tell you your voltage, and shut your gun down to prevent complete drainage of a LiPO
-Triple click the knob to switch between burst and full auto

Cons:
-Easy to lose the front 'plug' on the tip of the suppressor part.
-The plugs can be shot out easily.
-Eats batteries fast. Get rechargeables for it.
-Only happened to me once but the MOSFET seemed to be misreading my battery and preventing me from firing despite me just charging it and testing it on a different voltmeter.

"I received mine a week ago. I'm so happy I can monitor my velocity, battery voltage and total bb shot.
My excitement suddenly fade away when I received my tracer bb's and find out that tracer function not working. I will call evike customer service tomorrow to have this replace. Wishing the one will be working perfectly.

"Used this in a few games now and it works great! The tracer never misses a shot and the chrono is very accurate. My only issue with it is the mosfet. I've had a few issues with it such as the option to stop your gun from shooting after a mag is empty. This eventually stopped my gun from shooting after a few shots. Other than that though everything has performed flawlessly and I was very impressed. For the price it is amazing!

"I bought one of these I really love all the features and programming isn't too hard, although I have never gotten the burst fire mode to work tried it on two diffent guns one with a factory mosfet and one without.

"Update:
Received my new replacement for the one that tracer does not work. I went to test it and now tracer light works but ROF is the one that's not working. What's up with this product excortech designer. Now I'm nervous for how long it's gonna last.
