Proline M4 RIS Airsoft AEG w/ Crane Stock

Overview
The Gen 2 ProLine is the newest addition to the lancer tactical family. This rifle series is an evolution compared to the standard Gen 2 model. These rifles feature a full metal upper and lower receiver, full metal rails, and buffer tube. Not only is this gun upgraded externally, internally is where it gets even better. This rifle has an upgraded 18:1 gear set so there's a greater trigger response out of the box. It doesn't stop there, Lancer tactical introduces their new lancer fast trigger, this trigger includes a new flat trigger design. This rifle also includes a battery protection feature. When you have low voltage in your battery, the Lancer fast trigger will cut off any remaining energy from the gun to the battery and protecting your LiPo battery from dying. This also means the rifle is LiPo ready. This rifle also carries some Gen 2 internals like, a quick change spring system, a 6.03 Tightbore barrel, and a rotary style hop-up. The ProLine is the next affordable upgraded rifle out of the box. Battery Charger Recommendation: Lancer Tactical recommends the use of a smart charger to avoid overcharging the battery (overcharged batteries may cause decreased airsoft gun performance and may shorten battery life significantly). Smart chargers not only shorten charge time significantly (up to 800% faster charging), but more importantly, also automatically shut off once the battery is fully charged to avoid overcharged batteries.
