Purchased the Samoon Co2 Kit for the GHK Glock, while they include a few steel parts that aren’t steel in the pistol originally which seem of reasonable quality, the Co2 mag is awful and the Co2 ( Supposedly ) nozzle broke after 3 capsules.
To be fair it was great shooting it with Co2 for the very limited time I could, but for what is a very expensive kit, especially with posting and charges, my advice, DON’T.
