According to ASG Olsztyn, the Double Eagle Sako TRG M10 Airsoft sniper rifle is praised for its exceptional external build quality, featuring a robust body, licensed markings, and a highly adjustable, folding stock that makes it visually appealing and solid to handle. However, the rifle's performance in shooting tests was disappointing, with it struggling to achieve consistent range and energy, especially when attempting to use heavier BBs.

A detailed internal inspection revealed the core reason for the performance issues: most critical components are proprietary and made of low-durability materials, such as non-steel sears in the trigger unit and a short aluminum piston. While the inner barrel and bucking offer VSR compatibility, the complex and proprietary hop-up chamber, coupled with the overall lack of dedicated tuning parts, leads the Ulat to conclude that the Sako TRG M10 is best recommended as a high-quality display piece rather than a reliable platform for aggressive use or performance upgrades.
