RetroArms is a Czech airsoft company which manufactures high-quality upgrade and spare parts. The company has become known from its CNC machined parts, especially its super durable gearboxes which are made from 7075 aluminum. RetroArms gives its gearboxes a lifelong guarantee against breaking which tells us a lot about the quality of the parts!
CNC machined hop-up chamber is compatible with most manufacturers' AK series and their copies. High-quality and precisely manufactured chamber guarantees not only good airtightness, but also an even back spin, thus improving accuracy compared to stock chambers. A very good purchase for every tuner!
The chamber comes with the necessary small parts (not incl. C-clip) and on top of that they are manufactured of machined aluminum!
