Powerful airproof Piston Head [SLONG AIRSOFT]

The SLONG Airsoft Powerful Airproof Piston Head is a simple yet effective internal upgrade designed to improve compression and overall efficiency in AEG gearboxes. Made from durable polymer with a well-fitted O-ring, it provides a noticeably better air seal compared to many stock piston heads. This results in more consistent FPS output and improved shot-to-shot stability.
In use, the piston head performs reliably and helps reduce air loss during compression, which can slightly enhance range and accuracy when paired with other well-tuned components. Installation is straightforward for users familiar with gearbox maintenance. While it is not a high-end performance part, it offers excellent value for its price and is a solid choice for entry-level or mid-tier builds seeking better efficiency without significant cost.

Great product, air seal is garanteed it also improves the reliability by helping to have consistent fps. Have use it in several cylinders from diferent brands without any trouble, if the cylinder head does not have a pad all the players in the field will know when you ran out of bbs.

piston head purchased because it is similar to a product of another brand but which costs twice as much, well it is the same. very valid product used with 34bbs ssg configuration and it has given me enormous satisfaction in terms of constancy of fps. as a professional installer I recommend the reinforced Gearbox if you want to go really fast otherwise it could shorten the life of the Gearbox.
