with so many brands copying beretta on their argo gas system it seems that pricing on the m4/1401's have come down? with that in mind i've found a 7 round fde 18.5" model w/adjustable stock for 2k (also in stainless and black). fixed stock versions are $200 less. so that saves $700-1,000 for not needing upgrades and it has the extended bolt releases and chargehandles.
