Heckler and Koch H&K Competition MP5 SD6 SMG AEG Airsoft AEG by Umarex

"As just recieving this gun, I can only give a proper review from a first hand look. After opening this from it's box, it was sturdy, good weight, and is truly unique in detail. A reliable and retractable stock, great range for CQB, optional suppressor, and overall unique weapon is why I have no regrets saying this weapon is worth your cash. If you are like me and have little experience in upgrading your weapon and only playing with it from stock, then it is perfect for you.

"Great gun, right when I took it out of the box I knew it was a great purchase.

"I put a mosfet burst wizard onto this with an 11.1 matrix 1500 ml straight from the box, it totally impressed me. Well I know it recommends 7.4 lipo but after opening it to find what made it tac so hard for. Well I stil found more that impressed me even further a full rack of iron teeth as well as the pick up tooth. I changed the cilender head with some used mp5 part because the stock plastic one wouldn't last long in full auto. Testing the piston air seal I had to change the air nozzle to make a perfect seal from the stock piston and head. In closing I installed m130 spring using the stock spring guide. Then placing m120 G&p motor in I used it in a long day of scrimmage and made it successfully threw the day with no real issue. Thank you for supplying quality products at fair prices.
