If you want something an MP5A5 AEG smaller than the standard one, then you can try the Tokyo Marui MP5A5 Mini AEG if you can find one. Johnny's Room tells got one to over... "The "Mini Electric Gun" series, a fun toy gun for ages 10 and up that Tokyo Marui has been selling for nearly 30 years, has been discontinued. This time, I repurchased my favorite MP5A5 from the distribution inventory and played with it. The firing power is weaker than 0.98 joules and does not violate the Firearms and Swords Act of Japan."
