MP5 Airsoft GunsReviews and Ratings on MP5 Airsoft Guns

I’d recommend an A5. (retractable stock, plastic hand guard)
The reason for that is, retractable stock allows you to shorten the gun down for storage or allows you to choose from stock lengths which you are comfortable with. (But mostly storage, because you would have to be 4 feet tall for the MP5 stock to be too long for you.)
Why I wouldn’t go for an SD5 or SD6 (integral suppressor) is because:
1.Real Steel reason: MP5SD’s were made back in the day when suppressors weren’t as effective as today. True it was the most advanced suppressed weapon system of it’s day, still sets the industry standard, but nowadays is pretty much obsolete due to advancements in firearm suppressor technology.
2.Tactical reason: Since the front hand guard of an MP5SD is the suppressor, you can’t swap the hand guard for R.I.S. It restricts your options.
When it comes to guns, there is no such thing as “best”, so you have to have your options open.
