Achieve perfect FPS control with Rapax Power-Up Rings, engineered for precise power customization in spring-powered airsoft sniper rifles. These durable steel spacers enable incremental power adjustments—simply stack them on your 9mm spring guide to fine-tune your rifle’s output. Ideal for airsofters seeking consistent, field-legal power levels.

Key Features:

• Precision Power Tuning: Includes 3 steel spacers (8mm, 6mm, 4mm) for granular FPS adjustments.
• Durable Anti-Corrosion Build: Chemically treated steel real-firearm bluing to resist rust and wear.
• Universal Compatibility: Works with 9mm spring guides in popular platforms like Silverback TAC-41, SRS, Novritsch SSG10, 24, 96,  Scorpion piston set, WASP piston set, and others.

How It Works:
Install one or multiple rings onto your rifle’s spring guide to compress the mainspring, for higher FPS. Reverse adjustments by removing spacers to lower power output.
