Umarex 22 rds Magazine for H&K VP9 GBB

Despite everything you can read on the internet and on on the manufacturer's manual, we recommend that you never introduce silicone or grease into airsoft magazines. Greasing has a devastating effect on a replica since it will directly grease the hop-up rubber and inner barrel, resulting in a loss of precision and even more accentuated dust fixing. Never introduce chemical products such as grease, silicone spray or any other kind into the magazine, the hop-up unit, the BBs, the internal parts of the AEGs. The silicone is only used on pneumatic parts such as a gearbox cylinder or a moving O-ring. Special recommandation regarding Mid-cap Magazine :

• Limit the number of bbs by 70-80% of the mid-cap capacity, never force the introduction of the BBs with a BB loader.
• Too many BBs can slow down the operation of the nozzle and that can have repercussions on the trajectory of the bbs and the feed.
• If you want to keep your magazine for many years, it is also imperative for not working the spring to the maximum of its capabilities.
• Never store your magazine filled for a long period of use, the spring loaded for a long time may be irreparably damaged with a settling effect.
• Use BBs with irreproachable sphericity
