there is no set weight for a back plate and wings. I have them from my SS FredT BP that is at least 7 lbs to a lighter version by DeepSeaSupply at about 5 to my Kydex/SS BP (Also by www.DeepSeaSupply.com ) that weighs in at about a pound. If you do a search you will find a TON of info about these types of BCs.
