WELL VSR-10 BAR-10 MB03 MB07 Series Airsoft Sniper Rifle Power Up Kit

This kit is designed for VSR-10 style platforms, including the WELL, BRAVO, BAR-10, TSD M700, Matrix, and the MB03 and MB07 series. If your rifle is a Tokyo Marui VSR-10 clone, it is highly likely to be compatible, but always verify your specific internal layout before purchasing.

While it is a straightforward upgrade for those familiar with airsoft internals, it does require disassembling the bolt assembly. If you have never opened a gearbox or bolt-action cylinder before, we recommend following a step-by-step video tutorial to ensure proper reassembly.

Yes, absolutely. Increasing your muzzle velocity to 500-550 FPS puts considerable stress on your rifle's stock trigger sears and cylinder. We strongly recommend upgrading your trigger box and cylinder components to reinforced steel versions simultaneously to ensure your rifle doesn't fail after a few shots.

The bearing spring guide allows the spring to rotate freely as it compresses and decompresses, which reduces friction and spring torque. This results in a smoother bolt pull and can help maintain consistent FPS shot-to-shot.

While this kit increases your muzzle velocity, it does not inherently improve accuracy. To take full advantage of the higher FPS, you should pair this upgrade with a high-quality tight-bore inner barrel and a precision hop-up bucking to ensure your BBs remain stable at longer ranges.
