Just buy a good anti fog to go with it and maybe a fans kit.
If you really like AKs get either an LCT or a Real Sword you wont be dissapointed. The cyma AKs are okay but there are much beter built of much beter materials and beter internals cyma sre good cheap AKs but for 350-450 you can buy a full steel and wood (or polymer if you dont want wood) LCT looks as close to real as you can get built sturdy (prolly sturdier then a real ak lol as in no wobbles or creaks or rattles) great color and grain on the wood and strong internals. Also the have a tightbore barrel from the factory.
