Crosman Foursight Operator 5000 (Mod)

Did you print the Crosman Trisight Operator 5000 and then discover a forgotten rail mount accessory that needs another rail?? ME TOO!! Solution: Another rail. Print this and replace the original part. No dismounting from the Crosman rail required. My flashlight/laser unit didn't have proper rail retention so i drilled and tapped a couple of set screws (grub screws for UK) to assist with positive mounting force.
