Sniper-AS does a review of the Lancer Blazer 10" Proline ETU Gen2 AEG they have at their store. Lancer Tactical, a rising American brand known for its beginner-friendly airsoft guns with a great balance between affordability and quality, is making its way to Europe. Their products, including this classic M4 replica, are built with mostly metal parts for durability and feature an electronic trigger system that improves responsiveness and prevents jams. To get the most out of this airsoft gun, a strong LiPo battery is recommended, and the spring can be easily adjusted for different playing fields.
