ARES - L1A1 SLR Rifle Mid-Cap 120rnd Magazine this is a replacement magazine for the 2016 Ares SLR AEG.
The magazine features a Realistic Looking Design, with an Alloy Outer Shell and Polymer Internals, as with any midcap they must be prepped before use by lubricating and then loading around 5 bb's a time and then empting until the full load is reached.
To prolong the life of the magazine always empty out the bb's when not in use or putting into storage.
