HGBD 015 Jegan Blast Master: Part ID & Assembly Tips

Quick answer

This guide walks you through runner identification and assembly steps for the HGBD 015 Jegan Blast Master, with common mistakes to avoid for a clean build.

Assembly steps

1. 1. Identify runners and check parts: Lay out all runners and confirm each part against the manual. The Jegan Blast Master uses several small polycaps for the weapon joints; verify these are present before starting. Missing polycaps are the most common oversight. Check twice before cutting.
2. 2. Build the torso and head first: Assemble the main body per the manual's order. The shoulder beam rifles attach later, so leave the shoulder pegs clear. A common mistake is forcing the head joint—align the polycap notch exactly with the torso peg. If the head feels tight, check the polycap orientation rather than pressing harder.
3. 3. Assemble the backpack weapon system: Build the back weapon with its opening panels and expanding barrel. The panels click into place on small hinges; test the movement before gluing. The barrel extension uses a sliding peg—do not glue it if you want the function. Dry-fit the barrel extension to confirm smooth sliding before permanent assembly.
4. 4. Attach backpack and finalize arms: Connect the finished backpack to the torso. The Jegan Blast Master's backpack is compatible with other HG 1/144 kits, but align the connection tabs carefully. Then add the shoulder and leg beam rifles, ensuring they can pivot freely. If the backpack feels loose, a tiny drop of cement on the connection tab (not the peg) can secure it.
