There are dozens of used BDLs on Gunbroker completed auctions, that either sold or didn't even draw a bid at under $500.
Bullschit.
LOOK at those auction listings.
Don't confuse plastic stocked SPS and ADLs with BDLs
There are NO
walnut stocked BDLs that sell for less than $500 on that site regularly. The ones that get "no bids" have RESERVE prices over $500 them have reserve price(Which is why nobody bid).
Hell, a brand new NIB BDL now costs over $750 wholesale.
