Ok so please bear with me as I am a bit of a noob. I brought a umarex hk45 usp. I can’t figure out how to adjust the hop up and the manual has no information about how to do it. I’ve had a kwa version in the past and that was straight forward but this is different. I’ve searched the forums and you tube/google and all I have found is how to adjust to compact with the screw under the muzzle. Which mine does not have. This has me completely stumped. If anyone has any experience with this issue I’d really appreciate the help. Thanks
