    "Slammed one of these in a stock new G&G combat machine with a brushless motor, modify bucking and a laylax tightbore barrel. performance is stellar, the latch system is great, the window in which you can finally visibly see the bbs is great. everything is great about it honestly, if you want to up your performance overall get one! comes already assembled out of the box with 3 in total hop up arms very sturdy and all around will last you a VERY long time

    also to MY understanding the Maxx Pro M4A is meant for most AEG's.... again just my understanding, i could be wrong

    "Got this in my new MARS II Carbine. I've used the standard model in a few ICSs before and they work with minor modifications. This time I got the proper MI PRO version and it fits perfectly with no needs to changes. It's a little better than the stock chamber (ICS use the same style as stock) but I like that it has r and flat hop capabilities designed in.

    "I got an MI Pro for my ICS EBB based build. Another reviewer said the 21mm nozzle didn't work for their application, but it worked fine for me. Depends on your individual build. Both the nozzle and the hop up unit increased FPS by about 15~

    Measured with a digital caliper, the stock ICS nozzle was 20.9mm and the SHS AK Long nozzle was 20.7mm. The Maxx 21mm nozzle gave me a 5 fps bump over stock. The SHS AK Long dropped fps by 30. Compression with the AK long was good, but it would cause a gap between the nozzle and the bucking since it was too short. Although, they all fed EF .25s out of a KWA K120 @ 26 RPS.

    5/5 if you can get it to work
