The Micro Reg GEN2 stands a hair over 2.25″ tall which makes the entire regulator more compact than traditional one. Its low-profile design it allows tanks to fit more easily into compact packs popular with minimalist loadouts. This is all done without sacrificing performance as well since this tiny regulator has a lightning fast recharge rate that is on par with its larger brother the MRS; The Micro Reg GEN2 shares the exact same internal components as the UGS and CGS and only has a total of two o-rings in its entire assembly which further promote reliability. Additionally, the GEN2 has a two piece body similar to the large MRS making it much easier to maintain.
