VFC SCAR-H MK17 GBB Countweight O-ring (Part # 09-07)

The heavy reciprocating assembly of the VFC SCAR-H MK17 gas blowback rifle places an immense amount of stress on internal seals. Because of this violent action, using high-grade replacements is absolutely necessary to preserve consistent cycle rates and overall gas efficiency. The VFC counterweight O-ring, designated as part number 09-07, is a critical factory-original component designed specifically to seal the counterweight mechanism and absorb the heavy kinetic energy of the bolt carrier group.

For dedicated airsoft technicians and skirmishers running this heavy-recoil platform, keeping a fresh counterweight seal is vital to prevent devastating pressure drops and sluggish cycling out in the field. Crafted from a high-density, oil-resistant rubber compound, this black O-ring is specially formulated to resist degradation from silicone lubricants, green gas, and propane. Weighing practically nothing, it creates a perfect seal in the internal chamber to stabilize pressure and cushion the rearward bolt stroke. The package includes one exact-fit counterweight O-ring ready to keep your primary weapon running at peak performance.
