This text appears to be an assembly guide for a custom NERF blaster, specifically the "Plunger Tube" or PT version. Here are some key points to consider: **Components:** * A ~5.5" mainspring of your choice (K25/6, ACE#49, etc.) * M2 or #2 pin to run through grip & trigger * [Dash 213](https://www.mcmaster.com/9452k33) o-ring * Small extension spring for the catch * #6 bugle or flat coarse-thread screws * Gasketing between the PT and frame or another PH oring or a dash-316 oring * Plastic-safe lubricant of your choosing **Assembly Instructions:** 1. Put the o-ring on the Plunger Head. 2. Insert the Plunger Rod into the Rear Structure, through the Catch Plate, through the mainspring, and into the Plunger Head. 3. Lubricate and slide PVC over plunger head into structure. Slide Frame Ring over PVC. 4. Attach top structure and front structure with #6 screws to assembly. 5. Insert small catch spring into Catch, Catch into Grip Frame with Cam and Trigger as shown in internal image in posting. 6. Add Grip Cover and attach grip to assembly with 3 #6 screws. 7. Cut #6 screws which protrude from assembly to length. **Hotfix:** * Drive a short screw through the top into the ring to help prevent flex in the frame that causes the catch to miss occasionally. **Optional Steps:** 1. Add scales using #6 Pan-head screws, chicago screws, or bolts. 2. Cut a hole in craft foam and install onto barrel of your choosing. 3. Load dart(s), pull plunger, and have fun! **License:** * This design is licensed under CC:A:SA:NC, which allows for personal use and sharing, but prohibits commercial use without permission. * Printing service operators are allowed to sell this item to individuals who request it specifically, as long as no listing, images, or marketing for this thing is promoted on their site or storefront.
