WELL VSR-10 Power Up Kit

This kit is compatible with a wide range of VSR-10 pattern rifles, including the WELL MB03 and MB07 series, BRAVO, BAR-10, TSD M700, and Matrix models. If your rifle is a standard VSR-10 clone, it should fit, but always verify your specific model's internal design before purchasing.

You can expect your muzzle velocity to jump to the 500-550 FPS range. This is a significant increase, so ensure your local field regulations allow for this power level before installing the kit.

Because this kit uses a high-tension M170 spring, it puts extra stress on your rifle's internal components. We strongly recommend upgrading your trigger assembly and cylinder to reinforced versions to ensure your rifle remains reliable and doesn't break under the increased load.

The stainless steel piston and bearing spring guide are designed for durability and smoother operation. The bearing spring guide, in particular, helps reduce spring torque, which can improve consistency and make the bolt pull feel slightly smoother despite the higher spring tension.

Installing this kit requires disassembling the bolt assembly of your sniper rifle. While it is a straightforward process for those familiar with airsoft tech work, it does require basic tools and some mechanical aptitude; if you are uncomfortable taking apart your rifle, consider having a professional technician handle the installation.
