fit the charging handle to the slot in the receiver by carefully filing the
tabs on the back of the charging handle. Lubricate the slot when fitting to
make sure it slides freely.
Fit the feed tray so it sits perfectly flat on the bottom of the recess in
the receiver, it must fit properly for good feeding.
With the feed tray in place, mark the arch in front on the receiver to
shape the feed ramp, remove the feed tray and file or dremel the feed
ramp to the proper shape.
Now the feed cover can be fitted. If the feed tray is properly fitted the
feed cover should close easily. The back of the feed cover latch should be
even with the receiver, it may be necessary to trim a little off or the feed
cover will not stay latched when firing.
