Depending on what materials you have, you'll need a combination of bendable sheet metal and epoxy. Got a pic of the damage? That will tell you how salvageable the parts are and what elbow grease and whatnot is necessary to bring it back to working condition.

ok so this is what i have right now

the part that is circled is what broke and the arrow is pointing to the seam of the crack.

i have gorilla glue and all the pieces.

tools on hand are a dremel with 40 heads, drills and the smallest bit being 1/16

so far i have glued everything in place but its not dry yet.

i was thinking if this doesn't work i could glue a block of something on to the back of the retention plate and use the force of the buttstock plate to hold everything in to place.

This was my fix. It held the gearbox in place just fine but i definitely could have done better if the tolerances were right. The metal i used was this really soft sheetmetal that i scrapped off an old computer PSU but once i clamped them together it was a solid piece and reinforced to prevent further breakage. I lost the pieces of plastic mind you and i didn't have the tools to put it back together in the same place.

You'll probably need to find something else like polycarbonate and use a solvent to weld everything together. Weldon-16 is a godsend for airsoft since it will weld most ABS/PC plastic that is used to make these non-metal parts.

i'll get some of that tomorrow, or some high strength epoxy putty to build up the rear and sides. if it breaks again im trying my block idea. in the mean time ima see if theres any info on the new king arms 93 p90 with the 9mm gearbox.
