It needs to be a fair contest.
Underbidding a contract by "forgetting" royalties, isn't a fair contest.
There are a lot of shennanigan that often go on behind the scenes in all of these deals.
I don't blame Colt for protesting. If you lost a contract because someone underbid you by say 3% and the contract was awarded by not taking into account the 5% paid to you for the design is not a fair contest. That deal isn't actually mathematically cheaper.
Nor is submitting a bid based on modifying the delivery requirements, which is one of the things I suspect may be part of the argument. Remington is saying it isn't fair because now Colt "knows their bidding strategy".
When I used to take bids from suppliers for equipment, if a company bid a job to a modified specification and it was acceptable, I gave all companies an opportunity to bid to that modified specification. Otherwise, they were told to bid to the specifications.
I am no longer participating in gun forums.
