Allso got one of the first batch, mine if absolutley fantastic.
The only issues i got;
Had a problem with magasines splitting when filling it with to many bb´s.
I have glued mine together with locktight.
I allso lost my foldingstock release "button"I discovered that the two small screws that secure the stockrelease was missing. I was wery lucky to find it again in the forrest!!!
Have downgraded my gun to m120 and use it in the woods. Using it in medium/long ranges works perfect for me.
I cant find a reason to use my other m4´s now, this gun is the most "complete" gun
