Snakedoctor,
If you can not get a response from the seller you purchased the stock from and you payed with a credit card you can take the following action to get your money back including all shipping cost incurred by you.
Box the stock up and ship it back UPS, determine what it will cost you to ship the stock back,. Ship the stock back to the seller C.O.D., add your shipping cost and the cod charge together and the seller will be required to pay this amount in order to get the package. Once you have shipped the package contact your credit card company and file a charge-back on this transaction and give your credit card company the UPS tracking # for this package. All that is required of you in order to receive a full refund from a charge-back is for you to be able to provide evidence that you returned the item to the seller.
Once you have filled a charge-back with you credit card company your account will be instantly credited for the full amount of the original transaction, but will be in a pending status until the package reaches the seller.
If the seller accepts delivery of the package your refund will be completed and the seller will have paid for the shipping cost you incurred to return the package, if the seller refuses delivery on the package it will be returned to you and you will be out the shipping cost of the package and the cod charges but you will get the item back. Your credit card account will be credited the full amount of the original transaction whether the seller accepts or declines delivery of the package as the only evidence you are required to provide is that you returned the package to the seller.
Snkaedoctor - Since you are not the only one that has purchased this type of stock and incurred a failure and or personal injury, Another avenue you may want to consider is as follows. There is currently a private shooting group that are conducting tests and gathering evidence to determine if these stocks are dangerous to the public. after all tests are completed and all evidence gathered the group will determine if the evidence collected will justify a further action against the manufacturer and or any agents of the manufacturer. If you would like more info about this action you can PM me and I will provide contact information to you.
