any lower will work if your upper is "stupid colt screw thing" you may/will need and adaptor
your lower bits may not fit (hammer and trigger pins) as colt also has used stupid sizes there too over the years
try wolverene or arms east for the lower and any bits you may need

If it's an SP1 lower than it should be a "large hole", this refers to the pivot pin. No biggie, bushings are easily available that will make it work on a regular lower.
SP1's used regular size trigger/hammer pins so they should work in any lower without issues.
