Airsoft (TM) USP AEP Barrel Brace/Stabilizer

prusaprinters

<p>I noticed that the barrel in my TM USP AEP would slide in/out relatively easily, perhaps in part due to a damaged hopup-barrel clip.</p> <p>When manually pushing the barrel in/out while chronoing, I would observe change in the output power/speed. The results also varied with different buckings.</p> <p>So I devised this simple design, a 3d printed piece, to hold the barrel tightly towards the nozzle, and keep it there. (to achieve a good and consistent nozzle-hop seal)</p> <p>However, the mod requires that the metallic trigger-block piece be modified (check images) for screw threads. Also, it cannot be done with the stock battery connectos(at least in the way I did it).</p> <p>How to do the screw mod:</p> <ul> <li>Be sure to clamp the two pieces of the trigger block together tightly (eg. in a vise)</li> <li>Drill a ~3mm hole at the front (check images)</li> <li>Tap the hole to 4mm (or try a ~2mm hole and 3mm tap, but I didn't personnaly have good results with the 3mm, maybe because I used a 2.5mm drill)</li> </ul> <p>How to assemble/how it works:</p> <ul> <li>Slide the piece onto the barrel</li> <li>Install the barrel into the hopup</li> <li>Add the M4 screw and tighen down (not too much but firmly) the brace to the trigger block</li> <li>Adjust the position of the barrel to the desired spot.</li> <li>Tighen the clamp via M3 screw and square nut (should be easy to modify for a regular nut)</li> <li>Optionally, fully tighten down the brace to the trigger block (don't overdo it)</li> </ul> <h3>Print Settings</h3> <p><strong>Rafts:</strong></p> <p>No</p> <p class="detail-setting supports"><strong>Supports: </strong> <div><p>No</p></div> <p><strong>Resolution:</strong></p> <p>200</p> </p> Category: Sport & Outdoors
