Our take: Systema is renowned in the airsoft world for their top-of-the-line craftsmanship on all their manufactured parts and products, and is also attributed with having a world-class R&D process through which all products undergo prior to making it into their product repertoire. It's no wonder why more airsoft-enthusiasts choose SYSTEMA as their upgrade part of choice, over the many other brands of upgrade parts available.
- Manufactured from silicone, making it difficult to be deteriorated by atomized oil grease during firing conditions
- High threshold of tolerance against corrosion/hardening
- Hop-Up Packing unit comes together with sleeve that keeps barrel/chamber centered to maximize accuracy and preserve a tight air-seal
