Tuning Help with sig mcx

I'd say GOOD LUCK since SIG don't care about their customers after they got your money.

I would generously use Alphabet org Trans stop leak quick fix in a spray bottle or a syringe and generously wet the area it's leaking from and also into the co2 inlet where it punctures in hopes it swells the seals enough.

You need to tell that buddy to give you a gun that doesn't leak next time! LOL

Good luck with it John. Might want to ask at GTA as well?

Do they at least provide a part schematic? So you have a reasonable idea how to dis-assemble/re-assemble?

It might just be a O-ring, most likely metric. Otherwise, sell it off for parts to another sig owner that got stuck.

I do not recommend stop leak products. They will most likely gum up all the internals.

I had one and it ended up not being fun anymore.

NOPE! SIG outright refuses to disclose their secrets nor offer help or support to their customers.

Been there, done that. Google "Inside the MCX AIR RIFLE". All kinds of photos of the MCX's insides.

Our disposable society has creeped into our airguns. After owning mostly crosman's, I was shocked after getting Liberty's to find out that there were zero parts available. There are many others that have little to no parts support. Now, even crosman doesn't spare everything on every gun. I think the DPMS is similarly priced to the Sig MX, and only a few seals and springs are available, They do have schematics, though.

Unfortunately they don't take Airguns serious or those who enjoy shooting them. All Sig products are built like disposable kids toys.

Someone else makes them I’m pretty sure. They have a air gun smith on staff. I have a mcx and it started leaking all the air through the action as soon as you screwed the cart on. Had to pay 60$ plus shipping for them to repair it. Work order said some pin had fallen out, they replaced and sent it back. I’m either gonna get out of air gunning or buy a good pcp setup. Costs more than my freakin Ar15 though! 

I know that on Ebay UK you can pick up a seals kit, it includes the O-rings, flat washer & nylon seal for the CO2 cylinder.





Same seller has a kit for the .22 Virtus too

OLD thread but what the hell...

Throw it away, buy an RTI Prophet Compact and never look back.

After the leak is fixed it will likely start jamming, NOT FUN ANYMORE.
