late on the topic but i have a fix for it and it will feed 15+1 quite reliably...all i get now is the odd misfeed around max capacity but no jams...just line up the round in the mag well, reprime and good to go...ill post a few pics in a bit...unfortunately i didnt take disasembled pics but the mods are fairly straight forward
Here is a stryfe, simple paint job to give it some life. Running a 600mah li-ion at 8.1V. Inside is gutted of safeties and rewired.
picked this quick 16 for 4.99 at the thrift store..lots of homebrew mod for it to accept a full mag of elites and anti-jam mods.
Here is my no jam mod...2 guide rails along the bolt lug.
Hard to see but there is a special angle plate in the mag well to help keep the darts in better allignment.
Cut out in the feed doors.
It also has a doubled spring for a bit more oomph but unfortunately I have no pics of that one...Hope you guys like them.
