I agree I'd love to see a complete Geissele in house built rifle....however, only if all other aspects of the rifle are as good as it's trigger, rail, barrel, and gas block.
Basically Geissele needs a full ambi forged lower, with a colt quality LPK - Geissele trigger. They need to top the KAC IWS lower in my book. A Geissele upper rec. is another critical component. They need a MUR quality or better upper receiver.
