Yo dude.
I think there is still a waiting list for the X-Mag.
I dont know too much about bad points, the batterey box on the front is a bit big but suits the marker really.
Any level10 problems are easily resolved...as someone said, the carrier o rings wear in after some use..the trick is to go with the next tightest carrier but use the same o-ring.
The trigger has no springs or switches whatsoever...all the weight is adjusted by magnets, so you can have it as light or snappy as you like...no switch on it as the firing cycle is set off by the trigger blade passing a magnet in front of a Hall effect sensor (detects magnets) so it cant wear out...although you cant have full auto over here, they had one doing 26bps on full auto, the Halo manufacturers used one to test the Halo hopper at 20 or 22 bps, they wrote on the side of a barn the word HALO in 8 ft high letters like they were using a pen..and emptied a hopper, there is a video of this..try
www.automags.org for more info...they use cocker thread barrels now too....you get dual anti chop features that work separately from each other..the L10 bolt and the ACE anti-chop eye.
Get intouch with AGDE in my sig and speak to Jackie or John..good luck.
