here is a description from the sellers ad:
"Chrome lined RRA upper married to a Spikes Tactical lower filled with a RRA lower parts kit. I recently (within three months) added a YHM (YHM-9630-DX) free floating handguard. GG&G VFG and three 30-round mags are included. The BUIS was given to me by a friend and there are no markings on it. "
All three of the mags were loaded with Remington ammo.
hehehe - best part of it ALL was that we went to the range this mornin'....after some pistol plinkin', we went over to the rifle side - the dummy loaded it an' set it down on the table......yeah, I did - full mag run downrange!!!! Ah'm SUCH a bad father.....<SEG>
The best part is that after readjusting the windage knob on the BUIS she was only 2 or 3 clicks of center with 25 meter M4 zero target. next time out I will take more ammo and time for 100-200 meter with the iron sights. I gotta remember how to use iron sights again, haven't had to use them that far out in about 7-8 years(last time for range qualifications in service). At that time I was able to hit 6 out of 8 @ 300 meters on timer with random ups at 50, 100, 150, 200, 250 and 300 meters.
