Test Setup

It was important to test these BBs indoors as any wind would easily skew the results unpredictably. Unfortunately, this limited the maximum testing range distance to 35ft. 20 randomly selected BBs are fired at a Midway USA paper target from our test platform TM G3SAS with a stock mechbox and stock barrel. The AEG is secured using a MTM Case-Guard gun sighting/cleaning stand and sighted to the target via the stock iron sights. Since it is grouping size we are concerned with, it wasn't necessary to perfectly sight the gun as long as the firing position doesn't change for each batch. Marushin MaxiBBs were selected for sighting as they are expected to be the most consistent. The hop-up is adjusted until level flight is achieved for the 35ft range, and a regular bubble level is used so as to verify that the apparatus remains horizontal during the testing process. After the 20 BBs have been fired, the magazine is removed and reloaded with the next batch. A gun with a short barrel was chosen so as to minimize the effects of a lengthened barrel in increasing accuracy, placing the onus of a predictable flight path on the physical characteristics of the BB.
