Bushmaster complete lower L189XXX Serial Number. Bushmaster internals with an A2 stock. Has a few insertion marks inside magwell from mag insertion (of course) but otherwise has no marks on it.
Looking to trade for a Daniel Defense or Larue 12.0 or 9.0 ff tube. Would also consider a complete LMT SOPMOD stock with buffer tube, spring, buffer, etc.
