The first thing that you have to do is take the outside of the bigshock off, do this by removing screws. Save this you will need it later. Remove screws on bottom of bigshock, pull out plunger. Remove air restrictor. Drill out back of bigshock with 1/2 in bit, pull out grey thing inside. Remove support beams around it, and post. Drill out side of bigshock as shown in photo. Use drill and drill holes as close as possible, remove material with file. Drill hole right after trigger guard that is bigger than mag. Seal open back with hot glue. Make ring around the back, and let dry. Repeat process until Sealed. Make sure glue does not get in plunger tube. Sand main 3d printed barrel, until fits airsoft bb Sand main 3d printed barrel and small 3d printed breach thing (one to the left of main barrel), until they slide in and out with ease. (this will take a while) Drill hole in breach thing where screw will go at the top of the wide part. Put breach in with lubricant (lithium grease good) make sure hole visible through window. Sand mag, until fit in hole, right before suppressor. Sand little thing until slides in mag with ease. Drill hole in little thing in the middle. Add 1/4 in spring to mag, sand until slide with ease. Put little thing in mag, with spring, add screw in hole. Wrap main barrel in electrical tape, and shove in barrel, this should be stuck there. Align with mag hole, and trigger guard hole. Put screw in hole drilled in breach. Put mag in and turn to lock. Put plunger back in Put bigshock outside back on, after cutting it to desired outside. To load, pull tiny thing in mag down, until hits bottom, then turn, fill with 9 bbs. Put back in. and turn screw back. BBs should pop in place. Pull back screw on side until bb pops up (you will hear mag going up). Prime bigshock, and fire. Should shoot very hard, break thru card board.
