So, I am working on a longshot that shoots different types of ammo, including a 3 dart shotgun, megas, single elite, rival 1-3 etc. It will be running on 26 kg. I'm having a custom made metal plunger rod that functions as a pull back, akin nightfinder. The backplate is metal, the catch is metal, pretty much everything is metal except a stock plunger rod and a stock shell. I have heard at that high of a spring load it can warp or break the plastic. Is there any way to prevent this?

Use epoxy putty to reinforce the shell, and I'm slightly confused by your statement about the metal plunger rod then you go on to say its a stock plunger rod? If its stock, you can put thin pieces of metal in the grooves and epoxy them in; if its metal and you mean the plunger tube, you shouldn't have to reinforce the tube itself, but the front and rear plate, and screw ports. Epoxy putty and longer screws can help with that.

Sorry, I only meant plunger. Are there certain areas of weekness I should focus on? Also, I have seen people put foam in crossbows, what about that?

So, if that's the case you should pad the plunger head with rubber/ foam and use a longer screw ( depending on the size of the existing screw ) to hold the plunger head to the plunger rod. People put foam inside the blaster to dampen the sound of the plastic echoing since you've removed the air restrictor. It isn't necessary, and I haven't used the method much to let you know how well it works.

You need to reinforce the back piece in the shell that supports the plunger tube. This is because even with the metal backplate, pressure is still being put on that back piece. Same goes for the front one in front of the plunger tube. You can epoxy metal or polycarbonate sheets to cover these spots. A 26kg spring is super strong, and will vibrate the stock shell. Buy an after market one (xzues), or put FBR on the inside of the shell. I'd highly recommend the xzues 2 shell, as it's pump action, and designed to take lots of pressure and stress from high spring loads.
Good luck modding.

I'll try to make the stock longshot shell work, but if not I'll buy a xzeus. It's minimized, and it's going to be pull back, so I would probably just sell the pump grip.
