Hey, So I bought a WE Tech MSK in black. It shoots well, crisp and hard recoil, easy maintenance, however I have been having issues with the hop up. - I haven't broken it in fully yet, but I can get a flat trajectory. - The problem is: On the first shot after a break, the BB will go about 40 feet then drop off. Subsequent shots are fine, but the first shot never has the correct trajectory. - Weather where I live is normal, so it doesn't have to do with that. Is there anything I can do? Thanks.
