Mine is the straight feed so I have to use the SSS ramp.

The ramp fits into the receiver fine, but, when I turn the receiver over the ramp falls back out into the empty feed box.

I think I have it now, by putting the little magazine locking clip back and running the receiver bolt through the retaining clip. The clip seems to hold the ramp in place (doesn't fall into the empty mag box cut out in the stock).

Again, what am I doing wrong. thanks rc
