USAirsoft reviews the Lancer Tactical M4 KeyMod Gen 2 AEG part of the LT-19 series that are available right now at Airsoft GI, the latest sponsor of the channel. Airsoft GI describes it as... "Internally, the 2nd generation of these Lancer Tactical come with standard Version 2 gearboxes, so upgrades and modifications are easy to come by. These upgraded gearboxes come out swinging with an upgraded motor, 8mm ball bearings to ensure the gears spin more efficiently with less friction, a quick change spring system, and low resistance wiring to ensure electrical flow from your battery to your rifle! The rifle also features a 6.03mm tight bore barrel, and a rotary dial hop up unit, to allow for more precise, accurate shots at range. This model shoots approximately 375 to 395 feet per second out of the box, making it field legal perfect for long range engagements!"
