This is on the H&K Full Size SL9 Airsoft AEG Sniper Rifle by Umarex sold by Evike. I don’t know where this topic is headed but hopefully I keep an open mind about it.

So in late fall of 2015 I bought the KWA G36 and the H&K Full Size SL9 Airsoft AEG Sniper Rifle by Umarex, always wanted these two so I got bought them. My first impression of the SL 9 was one of not bad nice polymer (hated the red tip). So I was basically happy with it. Then I notice that my thumb could not reach the select lever, not too happy about that. As I moved on I hooked up one of my 11V lipo’s and load the mag with .25g bb’s and wen to fire it on semi auto. At first the gun did not want to cycle properly then when it did fire it was not shooting well at all. But guess what than the gun stopped feeding, so I was like scratching my head to say HHHHHHHHMMMMMMMMM. Torn bucking on the very first try not good at all.

Ok Evike says that the inner barrel is 650mm long, this is very wrong the inner barrel is 660mm long and fits to the tip of the silencer, just being 10mm short cause the bb’s to hit the inside of the silencer. So I upgraded the hopup chamber with a ProWin G36 and a PDI buking.

If you use this Hopup chamber you will need to shim between the mechbox and the hopup unit it's self about .03mm or it will not feed at all.

More to come on the Mechbox later :banghead:
