If you have a pair of Xbox Live accounts or PSN acc's, you can try this technique. If one account is of a lower rank than the other, you can give the lower account an instant perk of your choosing. Go onto your higher account then When you unlock something at the end of the game (such as the Claymore Perk), immediately log out of your account and sign into the lower account. Head to the game lobby and press Y, and the game will have unlocked for this particular account whatever you unlocked with the first account.
