Title: Sig MCX Conversion
Post by: Djbriez on March 27, 2016, 08:16:18 PM
A short time ago, Rick Eustler  posted a video on doing a conversion to HPA for the Sig Sauer MCX/MPX.
I have done this, and it works beautifully! I have run about 4 mags (4X30) thru it flawlessly (started at 3k now at 2k).
I will take a chrony to it once it's NOT raining here!

I saw that video also.  Looked like a nice, safe and easy way to. Not any different from going HPA on a paintball gun.

Just needed to add a bulk fill converter, and the proper regulator/bottle.

I thought the same....I just couldnt resist doing it now, with such minimal parts (some of which I already had).

Mike,
It's fun for sure! Sometimes, just taking a break from the serious "heavy metal"PCP's, and picking up something like this, and going nuts is wickedly fun!
I will try to get some string up this week if my weather cooperates, and my chrony cooperates...(I HATE my chrony)! I'm still waiting for the Caldwell G2

Thank you so much for the chrony data on HPA!  I was considering getting one of these guns and converting it to HPA as an upgrade from my 1077, but since this platform can push a tiny 5-ish grain pellet at 500 fps or less, it is utterly outclassed by my 1077 which launches 8-ish grain pellets at about 600 fps.  So what will the HPA Sig launch an 8-ish grain pellet at, based on this data? Maybe 300 fps?  Making this, by far, the weakest HPA rig ever made? I use my 1077 for protecting my backyard songbirds from ravaging English sparrows and starlings, and this data makes it look like this gun might only annoy those pests.  Thank you again for the data, you have saved me a few hundred dollars that I can now put towards the Condor SS that my wife wanted!

He hasn't modded anything yet. FAIK not too many if any have modded anything internally on the Sigs yet. No telling what is possible with them yet.
It's still way too anemic for me (I'm still waiting for the PCP). But you never know what clever GTA members can do with a new platform like that.

I hope that a little modding can improve the performance.  I really wanted to get one of these because they looked like a lot of fun, but I need more power than being just barely being able to poke a hole in a piece of paper at ten feet. I am looking forward to reading more about mods to this platform in the future, and I hope that one day someone figures out how to get enough power out of it to be useful!

Tom,

The rounds that I did measure surprised me with the "under performance" as well. I will be watching closely as well for any mods that will improve velocity.

Hello, I was wondering what type of buttstock are you using for your tank? Would you mind providing a link too please! Thank you! :)
Title: Re: Sig MCX Conversion

Do a search on yahoo. Paintball tank stock.   I found lots.

Hi Marcus,

I am using the one in the link below.....pretty standard fair (mine came off of a TalonP)

tear that sucker apart and lets see its innards a bit..surely we can do something to pick up the pace of them pellets.

I have handled one, but not shot one.

I still want one, just am not ready to jump that end of the pool yet.

My airgun addiction isn't down that semi auto road any more, at the moment.

It seems to only like the expensive Sig alloy pellets from what I gave read, and the air gun store owner where I handled one says.

On the plus side, the ergonomics are spot on for an ar-15 (I build them every now and then)the weight is nice.

But my wants are subject to change, as is everything.

Yea, I say gut it like a hog... Build it better, stronger, faster than before...like the six million dollar man.
Title: Re: Sig MCX Conversion
Post by: David Mccann on August 16, 2016, 12:17:51 AM
Probably only like them alloy pellets cause it can't spit lead any faster than a ant crawls. Not knocking your gun sir, just funin a bit... Its a cool gun, I'd like to play with one for a bit....cheers

Post by: mcboon on August 16, 2016, 02:02:21 PM
Hey guys, so apparently I purchased all of the item necessary to convert this gun to HPA, however there is a slight problem during the check out process.
Instead of purchasing Ninja PRO V2 Reg, I ended up purchasing a Ninja Standard adjustable regulator.

Mind sharing some thoughts?

Thank you for your time

They're very complicated, here's the guts to my MPX.  Also I tried an 1100psi reg'd Ninja on mine and I think I might have hit 600fps but they way they are they're not very modifiable.  I would like to see what they do if and when they come out with the pcp version.

holy cow.. that does look snaky in there. 6oo fps isnt too bad. if i had the xtra cash, id buy one to experiment on.. they seem cheap enough on price... but.... we are saving for a pcp compressor.. my brother and myself. thanks for the pics. definitely a diff set of parts than we are not accustomed to seeing around here... any idea on just what twist and length of the barrel??  cheers
Title: Re: Sig MCX Conversion
Post by: TleVta on August 16, 2016, 02:38:47 PM
Those Sig pellets are on the pricey side, all right. Will shooting those alloys be OK in that barrel long term?
I may want an MPX later down the road.
Title: Re: Sig MCX Conversion
Post by: Old Chief on August 16, 2016, 04:28:47 PM
I would sure think so. Sig had them in mind when developing the MCX/MPX.
Title: Re: Sig MCX Conversion
Post by: mcboon on September 01, 2016, 12:55:39 AM
So I've successfully purchased all of the items and connected to my MCX, the bulk fill adaptor, Ninja 13cu/3000 psi tank, and the butt stock. However it only let me shoot once, then I can't shoot after, I have to constantly cock the gun then I can only shoot. Did I do something wrong by any chance or am I missing something?

 
Title: Re: Sig MCX Conversion
Post by: Djbriez on September 01, 2016, 01:58:40 PM
Nope....I dont think youve done anything wrong....
First off...it's pellet picky ....I have success with the Winchester maximum velocity alloy pellets (4.32 gr)
Secondly, MAKE SURE you are using the tool to seat the pellets, and that they all are firmly in place
Lastly, (most importantly, as this was the reason mine was failing after every other round), MAKE SURE that the air tank is nice and tight!
I thought that mine was......gave it another mildly forceful 1/4 turn, and .....feeding problems went away!

I hope this helps you...fun gun when it cycles correctly.....not so much when it doesn't!

Thanks! I really appreciate it, I tried everything but my gun wasn't shooting at all, maybe it's just my luck. I'll probably just go with CO2 for now until I find the issue 👍

They dump their plans of releasing a .25 cal PCP version?
Was supposed to be released this year.....anyone hear any updates?
Title: Re: Sig MCX Conversion
Post by: mcboon on September 29, 2016, 11:08:42 PM
I've been doing a lot of diggings, inheard they stop doing the production due to some issues. I think they are not gonna make any PCP nor 0.22cal anymore.
Title: Re: Sig MCX Conversion
Post by: 45Bravo on September 30, 2016, 06:33:06 AM
I had actually called SIG a few weeks ago.
They have dropped all plans for .22&.25 in any of their air guns.

They are selling the .177 guns as fast as they can make them.
And in their foreseeable future, it's going to stay co2, with no HPA upgrade from SIG.

That is what I was told when I was connected to their airgun division. 


But gun manufacturers go where the money is.
We had a glock factory rep at the sheriffs range one day, he explicitly said there would NEVER be a single stack 9mm glock released, just the .380 (glock42).
5 months later, the glock43 hit the market.

If there is enough interest (and money to be made) they will do anything.

If they still keep selling the .177 guns well, we can only hope.
