G&P Stoner 63 TDC-7 Hop Up Assembly

Replace the original hop-up chamber in your G&P Stoner 63 airsoft replica with the Bull Craft TDC-7 Hop-Up Assembly. Its Top Dead Center adjustment system applies centered pressure to the hop bucking, providing controlled, repeatable hop adjustment for properly tuned AEG and HPA builds.

The TDC-7 is a complete, drop-in replacement manufactured from SLS-printed Nylon PA12 and finished in black. It accepts standard AEG-cut inner barrels and standard AEG hop buckings. The adjustment wheel, arm, arm pin, three different-size hop nubs, and wheel O-ring are included.
