When it comes to Airsoft Gun, keeping the internal parts in top working order should be a priority. Shims are an essential, though often overlooked, type of airsoft part that works to space internal parts, in this place gears, correctly. This reduces the damage caused by space gears properly and therefore stops teeth from not properly interacting with one another. We offer shims in a variety of thicknesses here at Just Airsoft Guns. With the right use of the right shims, they can be a benefit when trying to get the perfect fit, enhancing the lifespan and performance of an AEG gearbox.
