just bought a same as new karma eq from a member its 22 cal been talking to pj in florida super helpfull guy he is from what i gathered aea builds this gun but to donnly fl specks tore it part way apart the 500cc tank is way to long for me so i am cuting it in half building a shorter gun from it factroy there 13 7/8 long cuting it down to 6 and 3/4 it will go from 500cc to 250cc i am ok with that then i going to take 6 inchs off the barrle and shroude factroy is 600mm 
AEA karma eq mods

- Start date
As far as the tank goes AEA has smaller ones. I would try to see if one of those would fit ? Wouldn’t surprise me if they were the same specs. Maybe pj could answer that. Be way easier and safer than cutting and putting back together.

The most important Mod for the Karma EQ would be
an aftermarket entire trigger system.
not a little $0.001 little black plastic block that was Karma’s upgrade

I like the idea, 250cc is a standard length aea 52mm air tube, so theres no need to cut and re-thread the existing tank. It's probably cheaper buying it. You just need the barrel and shroud cut down and threaded. For refrence my s45 has a 250cc rear tank on it and the tube itself measures 8 7/8".

There is a set screw going through the trigger gaurd that presses against the regulator housing. I tighten up the set screw on mine to stop the flex

Check out my video on adjusting the trigger especially the part on shorting the pull and reducing the spring tension.

the most important things I would say is
1. A latch on the magazine to lock it in place.
2. A flat on the barrel tread adapter so you can tension the barrel.
3. A wheel on the hammer spring so you can adjust it easily. Requires a little mod to the stock see my video.https://youtu.be/aLfYoGqeckU?si=2mYdrD2iT0YmfKFp
3a. Incorporating in adjustable stock length.
4. A faster twist rate so you can shoot longer high bc boat tail slugs.
5. A bottle adapter so you can use carbon fiber tanks(saber tactical has made one iut soon.)
6. A little more machining done to reduce weight.

I did my 580cc bottle swap last week. I think it looks better and it saved some weight up front. Also added the 60mm bottle clamp with arca rail

Yes most carbon fiber bottles you are going to find online are rated for 300 bar. I didn't even know that fx 250bar carbon fiber bottles existed until they made the installation video for this adapter.
