Stuck at home with some time on your hands? Want to upgrade your airsoft gun but can’t afford much more than pocket change to spare? In that case, you’re lucky you’re reading this article, because there are a number of easy mods for AEGs that don’t take much more than a few hours to accomplish but will make a big difference in how your airsoft gun handles. What’s more, doing these modifications is a big help in learning more about how airsoft rifles function and how they can be improved! Start off by learning about some of the best DIY airsoft mods, and if you’ve got the skills to take advantage of a high-performing rifle, you’ll be well ahead of the average weekend airsofter! So here are the Top DIY Airsoft Mods you can do at home. Wrap your Inner Barrel If you’ve worked with an airsoft rifle’s internals before, you’ll know that the inner barrel is where the magic really happens: where the pneumatic power from the gearbox’s cylinder is paired with backspin from the hop-up. To encourage higher accuracy, it’s important to ensure the inner barrel isn’t rattling around inside the cosmetic outer barrel, and one way to do that is to wrap it in plumber’s tape, also known as PTFE tape, Teflon tape, or thread seal tape. This not only keeps the flexible inner barrel snug inside the much stronger outer barrel, it also works to dampen some of the harmonic vibrations of the inner barrel, improving shot-to-shot consistency. What You’ll Need: A pair of scissors Plumber’s tape, aka, PTFE, Teflon, or “thread seal” tape Your inner barrel or inner barrel assembly, removed from the gun How to do The Mod: This is probably the simplest mod in airsoft; it’s easy to find the materials and it’s easy to accomplish without worrying if it might damage your gun. Begin by taking the inner barrel, and wrapping a line of the tape around the barrel’s circumference twice. Since Teflon tape clings to itself, it should stick on pretty well. Make sure you’re holding the barrel taut against the tape so it clings to the barrel, too. Slowly begin to wind the tape down the barrel in a spiral pattern, continuing to hold it taut so it clings pretty firmly to the barrel. Once you get the spiral near to the hop up unit or where the hop up unit would be installed, do another wrap twice around the circumference. Snip the end and finish wrapping the cut end tightly around the barrel so it won’t come loose. If you took the hop unit off, reinstall it now, and test fit the whole thing where it belongs to the inner barrel. It should slide in with minor resistance. If it slides in loosely, do another wrap the same way, but on the opposite side of the barrel from the first spiral. If it is too tight, try to remove some of the Teflon tape at the top and bottom, leaving one full revolution of tape to keep the whole thing in place. DIY Airsoft Mod 1 - Seal your Packing (Bucking) The Packing (Official name in the industry), or the rubber sleeve inside your hop up that most call a packing, is used to grip the BB and provide backspin, is dollar for dollar the most critical component of any airsoft gun. Sealing the forward-facing end of your packing tight to prevent air loss is a contentious mod among airsofters. Some say it reduces shot-to-shot FPS deviation by several feet per second, others say it’s unnecessary with a decent hop-up packing. I always do it, simply because I see no reason not to. It’s inexpensive and doesn’t require any special sort of skill. What You’ll Need: Either plumber’s tape OR dental floss Your inner barrel with hop up unit removed but hop up packing still attached How To Do The Mod: As I mentioned above, you can use either PTFE/Plumber’s/Teflon tape or dental floss. I usually use the tape, simply because I’ve already gotten it out of the barrel wrap mod, but both should suffice. If you’re using the plumber’s tape, this mod is easy as pie. Take the tape and, where the packing finishes covering the barrel (on the end of the packing closer to the muzzle), wrap a layer of tape around the barrel and packings’ circumferences so it covers the gap between barrel and packing. Do about three layers and make sure it’s tight so it conforms well to that barrel-packing gap and prevents any air loss. If you’re doing it with the floss, that’s fine! You’ll need to have nimble fingers, though. Begin by wrapping the floss around the packing, about a quarter inch (5mm) from the end of the packing that will face forward in the gun. Pull the floss tight, and tie a simple square knot in the floss to cinch it to the packing. I’ve included a link to a short article on tying square knots; use the first method here because of the small size of the work-piece. Congratulations! Now just slide the barrel and packing back into the hop up unit and reinstall the C-clip that holds the barrel and keeps it from rotating in the hop up unit. The fit into the hop-up may be a little tight, and if it is, try rotating the whole assembly back and forth to help it slide into place.
