Troubleshooting Selector Switch/Optical Sensor Issues
MTWs manufactured after October 1, 2021 are equipped with the black Spartan Electronics board with an optical select-fire sensor. This sensor works by detecting a dark or light surface on the selector barrel. Detecting a light surface will set the MTW to semi-auto and detecting a dark surface will set the MTW to full-auto.


A sticker or paint can be used to ensure that the two surfaces are detected correctly by the sensor.

Video transcript: today on what the tech we’re going to be talking hop ups we’re going to show you how to install aftermarket hop up with your MTW so let’s jump right in and take a look at this today we’re going to take a look at how to install an aftermarket hop up in your MTW talk a little bit about compatibility first this is a pro win pro wins work just fine we’ve tested modify element krytac a few other sort of common rotary brands dial types are not going to work the only one that we know is problematic at this point is the max hop up we have made it to work but it is it does require some some effort to do that we’re not going to cover that in this video this will just be standard rotary style hop ups that drop in drop in relatively easily so first thing we’re gonna do is we’re gonna separate upper and lower receiver here this is a it does have the race to co2 stock on it by the way so you’re gonna notice we’ll disassemble it a little bit differently then if you just had a standard standard HP a-line or an external air set those side so disassembly pop the two clips in this case we don’t have to run the airline through because the airline is connected to the hardpoint adapter so we’re gonna disconnect the airline from the connector from the back of the unit big our cylinder out this is the same whether it’s a Reaper or an inferno here I’m gonna slide the stock hop-up out and if you were just doing something with the hop-up this is what you would do you just take it to this point you could disassemble the hop-up I’d do whatever you need to there since we are at going to replace the hop-up completely we’re going to pop the feed tube out as well and you can just rotate back and remove the feed tube now we’re going to need a three millimeter allen key for the two set screws on the top of the rail give them about a half each and your rail will slide right off now you’re going to need an adjustable wrench or one and a half inch wrench to remove the barrel nut barrel alright so all we’re gonna do is pull the spring off here put the spring on our Pro wind hop-up now to install the hop-up what we’re going to do is go at an angle and then there is a gap cut in the receiver here that your dial will drop through now you can slide the outer barrel over the inner barrel align your index you pin your indexing slot we reinstall your barrel nut tighten it down reinstall our rail tighten it down with our three millimeter allen key and reassemble and there we are
Ambi Selector Installation (Video)
Rich demonstrates how to install an ambi selector switch on the MTW-Spec platform.
Video transcript: today and what the tech we’re going to take a look at how you installed the ambi selector switch in your MTW so ambidextrous selector switch is itself pretty easy to install you will need to have already removed your electronics if you do not know how to do this please go watch the video on electronics that we have posted and use that as a guide for removing your control board before you attempt to replace the selector switch well it is possible to replace the selector switch without doing this we do not recommend it as you can very easily damage the switch here your selector switch the barrel can get caught on it as you’re trying to remove it or install it and and break that switch there so we always recommend removing your electronics before you attempt to change the selector switch now you will need whatever tools you’re going to use for that again we go for that in that video for the selector switch you really only need two tools you need a 3/16 allen wrench with a fairly long drive because we’re going to get the grip screw with that and then you will need a 2 millimeter allen wrench for the selector switch itself to remove we’re going to start by removing the grip when we remove the grips we’re going to have our detent spring our grip screw and our grip and then you’ll have the detent it comes out as well final thing will be our standard selector switch here so let’s go ahead and grab an ambidextrous selector switch and show you how to install that the ambidextrous selector switch is going to come with a few pieces in the bag you will get two screws they are identical you will get two paddles there are different lengths the you have the longer paddle which is our standard paddle which we generally put on the left side of the gun and you have the short paddle which we generally put on the right side of the gun but these are reversible you can pick which side you want them on either way is fine and then you will also get your ambidextrous selector barrels you will see it has the notch to take the paddle on both sides the side with the detents on it is going to end up on the right side of the gun so before we assemble this figure out which side we want the paddle on and use that as your reference so we’re going to put the long paddle on the left side like we normally do here you can see there is a cutout in the molded part here that matches the cutout on the barrel and these can be a little bit snug but if you sort of catch the the flat edge together and then kind of snap them straight together they generally go without too much trouble then we’re going to take our two millimeter allen key and we’re going to tighten this down if you want a little bit of blue loctite would not go amiss here but don’t use anything permanent because you likely at some point won’t want to disassemble this again so a little blue loctite wouldn’t be a bad idea but it’s generally not really necessary now second paddle we’re not going to install until we have it all back together so with the one paddle installed detents again go towards the right side of the gun so we’re gonna go ahead and slide it in now if we flip it upside down we can drop our detent pointed end first into the hole right here okay I’ll lay it on our side and let it tip back too much to the detent doesn’t fall out then we’re gonna get our grip here so the detent spring goes in the hole in the grip and then our allen key there are two holes in this grip because you have the ones with the airline but our allen key goes in the small quarter inch hole at the front of the grip and then we’re just gonna put it all together kind of sideways that prevents the detent or the spring from falling out and just sort of feel around until you thread feel the thread start there you go check before you tighten it all the way down that your spring is actually engaging on the detent you can sometimes get the spring kind of folded over and you don’t want to crush the spring so make sure it’s actually engaging on the detent before you finish tightening it down alright you can check that work working properly now for the second paddle or somebody going to do the same thing as we did on the opposite side line up the square edge pop it on take our two millimeter allen key and our other screw tighten it down there you go now you can proceed with reinstalling your electronics and your trigger and you’ll be ready to go so that’s how you install your ambidextrous selector switch on your MTW
Contact Yoke Disassembly / Reassembly (Video)
Cody demonstrates how to remove and reinstall the MTW contact yoke.
Video transcript: what’s going on guys today we’re going to talk about the mtw contact yo i get so many questions all the time asking me what is the contact yo the contact yoke is the piece that’s going to make electrical connection from your control board to your silhouette engine all right so we’re going to take a look at the contact yoke inside the upper receiver here you can see it’s housed in the rear of the upper receiver it has an indention in the upper receiver exactly where it fits so i’m going to kind of show you how i like to disassemble and assemble the contact you know mtw okay so i like to take a tool and i just kind of stick it in there and pop the contact you out move my airline out of the way while i’m here i’m going to go ahead and just reach inside with my tool here grab the wire and then pop the connector from the solenoid here i can just remove the contact you from the receiver and once i remove it i can go ahead and proceed with removing my engine from the mtw now the way i like to reinstall the contact is i like to go ahead and put my engine in pull my air line through and then once i pull my airline through i can take my contact yoke and i can run my wiring back into my receiver from the bottom of the receiver and out the back okay then i like to take and push my engine back just enough where i can get access to the solenoid connection here and then i can work my connector back into the solenoid okay once that i can just go ahead and push the engine back forward i can put my retention clip in to lock the engine in place now the only thing i really want to do is make sure that my airline fitting here is in the center of the mdw that way when you go to clip it in just push the airline over to the center of the contact yo line it up and it press fits right back into the receiver now again if the fitting isn’t in the center the contact won’t press securely down into the receiver and you’ll have to move it over just a little bit
