INSIDE THE SIG SAUER MCX CO2 AIR RIFLE PART 1

[@NKBC1689]

Thanks for the video. I took mine apart because it stopped shooting. The tank doesn't leak but I have a feeling it's part of the trigger mechanism not allowing the gas to propel the pellet

[@TK7837]

Hi, if the gun is cocked does the bolt release, if so look at the bolt assembly.

[@TK7837]

kzbin.info/www/bejne/gH6viZmuh8eth6s take a look at this 👍

[@thafirstborn2550]

How did u remove the faux supressor?? Just turn or twist it off.

[@Steve-yl6wv]

The big question for me is. Is there anything in there that improves the power beyond 4.5 ft.lb?

[@StormHawks120]

great videos, mine after sorted a trigger issue out as soon as i put the bottle back on it just blows straight through to mag any ideas thanks

[@a64738]

This confirms what I have been feeling on the trigger... The SIG is not actually semi automatic, it is in fact a double action revolver and that you can clearly feel on the horrible hard and awkward really bad trigger pull.

[@TK7837]

Yes it should just unscrew, from what I can remember. I don't think there was a locking screw, but I would remove the shroud first just to make sure.

Gibts ein exportkit für die mpx?

[@stevebirks9908]

Is that the original barrel

[@trippowens8821]

How’s u get that suppressor

[@codylarsen268]

Is there any way to convert to F.A.?

[@dantechunknown3760]

I think there is a way to make it full auto by tinkering with the blocking mechanism so it dose not lock up while holding the triger. Drilling out the valve pin maybe will improve gas flow.

[@yoda3784]

Daniel Petkiewicz There is no way of making this full auto, as the magazine feeds manually with the trigger pull.

[@dantechunknown3760]

Stupid me. You are right 😁

[@a64738]

The SIG air rifle is actually technically speaking a double action revolver, not semi automatic like it claims so it is pretty much impossible to make it fully automatic... Also it has 450fps and not 750fps like it claims, I don`t understand why SIG lies like that, one day it will bite them in the ass in form a lawsuit for false advertising.

[@The_Business_Developer]

Does anyone know what has been removed from the UK spec of this model which causes you to push the trigger forward before the next shot can be taken? From looking at this video (thank you) it could be as simple as the trigger return spring seen just above the top of the guard. I'm hesitant to open it up without knowing if it's a simple fix in case I cause an issue. Help appreciated. To head off the legalities comments: it's a recommendation not a law.

[@TK7837]

Hi looking back through the problems this is quite common, I'm pretty sure that this pin is for the spring guide to secure the 2 pieces together, take out the main spring and see if they come apart if they do then this is the retaining pin. I no longer have the gun so can't take a look, also post your link to your video.

[@МаксимИсаев-з3у]

Hello! Tell me please, did you manage to transfer the rifle to the air, instead of CO2?

[@TK7837]

@@МаксимИсаев-з3у Hi yes, it's mentioned in my posts

[@ebealienthy]

Hi, I've seen the videos now and Thanks for sharing. I like them very much, and I think that for the category

[@TK7837]

Hi thanks for your kind words, sadly the silencer is fake, it's up to you which one you decide the mcx Has a longer barrel.

[@jaseeman836]

i to have a leak in my mcx as its out of warranty i intend to take it apart and inspect,, how easy was it to strip and rebuild ???

[@Jamshoot66]

Hey there. What kind of lube have you used?

[@TK7837]

Yes this would be possible, but it would be a lot of machining new parts, you would be better off waiting for the .22 version if they ever release it?

[@eragonshadeslayer1]

Great job dude this will help me find where parts go if something breaks

[@TheWoodworm1972]

Are you planning anymore videos of the internals of this gun? If at all possible could you do one with all the components in place, the components you took out for the other videos you did. I'm looking to get one of these and running HPA through it! It'd be nice I had a full picture of the inside. Cheers.

[@TK7837]

Hi Chris, I'm thinking of doing another one,not sure when, watch this space.

[@captlD45]

Is this same set up as mpx?

[@TK7837]

Not sure what you mean by having to push the trigger forward before the next shot, the trigger should go back home on it's own. If this is a new gun then return it to the shop. If the gun is out of warranty and this has just happened then something is wrong.

[@hrcnick11]

The UK version has to be pushed forward cause they are not allowed “fully semi autos” it’s kind of like the bullet button in California. There is a British guy that reviews it that is were I saw it.

[@hrcnick11]

kzbin.info/www/bejne/jKi2q6WFfa6prq8 this video about the 8min mark he talks about it.

[@TK7837]

@@hrcnick11 That version is the latest PCP version. The version I had you didn't have to do that.

[@hrcnick11]

Do you live in the UK? That is the UK only version. In the USA we get semi-auto, so they would not sell that here.

[@TK7837]

@@hrcnick11 Yes, live in the U.K.

[@TheWoodworm1972]

I'm following this with interest! It's a complicated mechanism, more complicated the Airsoft version I've seen.

[@TK7837]

Hi Chris, complicated it is, because it has to comply with gun law. The SIG is not really semi automatic as such because the next round is indexed by you pulling the trigger and not the gun, just like a revolver pistol, Air soft and paint ball markers are as complicated if you consider gearbox's and valve systems they are quite complex but, are true semi and fully automatic, as the gun does all the work loading the next round. Pleas correct me if I have got anything wrong.

[@TheBsavage]

@@TK7837 Yeah, it's not semi-automatic, it's double-action, like the pistol you mention.

[@csah2k]

Help please, do you know the o-rings size in the brass tube?

[@TK7837]

Hi, no sorry, if you need a replacement just measure the OD ID and thickness and replace it with a NBR not silicon o-ring

[@TK7837]

Take your time and you will be fine, just make sure you remove all the screws first in the receiver and foregrip.

[@TK7837]

I would have thought so, it may have the same components but, the principal will be the same.

[@Tritorpol]

I have a issue that mine won’t shoot anymore, the co2 won’t go off like when I try to shoot it won’t. The trigger works but no co2 comes out? What’s the cause

[@brorjordas1979]

That big aluminium block in the center (working both as the blowback chamber and valve actuator) has a valve firing pin inside of it - at the rear part of it, close to the compressed black tubes behind it. Maybe the pin inside got damaged and therefore does not hit the valve.?. Hard to say - but would be possible, if not firing any gas but otherwise seems to work..

[@pollutance]

I was wondering if you could help me out? One afternoon I got distracted and left a fresh co2 cracked in the gun overnight, the next morning I go to shoot the gun and it turned into a damn fire extinguisher... It shoots the first pellet or two and then on the next shot the co2 just unloads out the barrel... Is there maybe something I can do to fix it, or is it junked? Thank you.

[@TK7837]

No not junk, you may be lucky the seals were not damaged over night (as they were frozen the seals wont seal), leave the gun to warm up and try again, this may not work and you will loose another Co2 or, strip the gun down and re lube all the O-rings this should do the trick. GOOD LUCK.

[@pollutance]

Thank you so much for the info I truly appreciate it, I'll give it a go and hopefully all is well with this gun. Again, THANK YOU!

[@kallesandberg2905]

Hello! My MPX is also in "fire extinguisher" mode :( Im going to take it appart and lube the O-rings as you suggested. This is not a problem, putting all together might be...... Will you be able to give some advise if I screw up???

[@boostedwolfie]

I have a loose part after opening mine up, it resembles a small nail or pin, like a half inch screw with no threads or allen key. Where the hell does it go lol!?

[@TK7837]

Hi without a picture l couldn't say, send me a picture and I'll see if I recognise it .

[@TK7837]

@@boostedwolfie it looks like the pin for the main spring, the plastic black thing that pushes the bolt forward?

[@boostedwolfie]

TK7837 it does look like that except this is black and smaller, the pin for the main spring is still in its bore.

[@tattiei]

Hi! Took my sig apart, cleaned and greased everything, had no problems. But I'm still wondering how the magazine should be, because there is somekind of spring that is just flat in mine, basically doing nothing at the moment. You happen to know?

[@TK7837]

Hi not sure what you mean, do you mean the magazine catch?.

[@tattiei]

TK7837 It's in the top section of the inner guide thats inside the magazine

[@tattiei]

So I was talking about the magazine itself, maybe I was bit unclear. But thanks already for replying!

[@TK7837]

I haven't taken a magazine apart so can't comment as long as the belt moves freely there shouldn't be a problem.

[@tattiei]

TK7837 Okay but thanks anyways! Pretty sure now that the magazine on mine has too much play(well I've shot 3000 rounds with it). It shoots off center and jams if I dont push the magazine upwards while shooting. I'll figure it out. Thanks for the videos!

Hi there a little black pin dropped out of mine. Any idea where it goes

[@TK7837]

Hi Dean, does the gun still function at all with or without mag installed? is the pin plastic or metal? I don;t recall any pins installed. It may be part of the mag, can you post a vid of the offending part?

[@Deanosparks1982]

Hi thanks for getting back to me. No it will not fire anymore. Like there is no co2 in it. It's metal pin it dropped out when I opened up the gun. I can send you a picture. Please can I have your email address

[@TK7837]

Hi Dean, post the pics on your page so everyone can see.

[@stephenboffa2557]

Hi, I literally had the same black metal pin drop out tonight when refreshing lubricant on the actions and valve and seal components. Best description I can detail: Flat head on one side, pointed on the other, actually looks a lot like this: ||======> , 5/8" total length; seemed to show signs of wear half way up like it was partially in a spring or used to anchor another moving part internally. Was its placement ever found? Wondering if it came from the top side of the shell (some parts like the other side of the safety mechanism stay with the top). Any help would be greatly appreciated! And MANY thanks for the videos on this as they were a great DIY guide! I'd hate to put it all back together without all the parts in their rightful place even if the action doesn't seem affected by it missing, so please let me know if you have any ideas on it's location.

[@thomasturbato7021]

sry for my english... had the same problem and i think it come out from that piece of plastic with a spring inside... is the only spot i can found

[@paolob7203]

Anyone here knows the inner barrel’s thread pitch?

[@TK7837]

Hi, as far as I remember it's just clamped and not threaded.

[@Agboshh]

is it no licence legal in uk?

[@yoda3784]

Yes, you don't need a licence to own one in the U.K. just a min age of 18 and a face to face sale. There are a few options to get one, go to your local shop and purchase one or see if they can get one in or find a good price on the net and have it sent to your local RFD this will cost you for this service £24 to £35. There is also the MPX both come with different options.

[@StrathpefferJunction]

Not strictly true. That only relates to England and Wales. In Scotland, you need an AWC and in Ireland this may require a firearms licence (can't quite remember the cutoff).

[@GravityCorp]

Ok. Im confused

[@jodopeg]

So let's get to what is really on everyone's mind about the MCX pellet rifle.... WHEN ARE WE GOING TO GET A 22 CALIBER VERSION...? Because for now, this rifle does not even stack up to a Crosman 1077 in terms of reliability, performance or accuracy at more than twice the price !

[@ProsperousHobo]

Probably never.... sadly
