Cylinder head PGM338 Cybergun by ProteK

The Protek cylinder head is entirely CNC machined from a 7075 aluminum block. It was made for CYBERGUN PGM 338. This part will give you a significant gain in precision and range! The dimensions of this part are very different from those of the original part, allowing you to place the bbs much more accurately in your hopup. Your bbs is immediately centered and will take full advantage of the hopup.
