NO Refunds or exchanges at anytime! Every single part we sell gets test fit and checked for funtion before it leaves here. Every single firing pin we sell is test fit into a bolt and test fired with a live casing, and then tested for OOB with a live casing before it leaves here. We will not be held responsible if the firing pins dont fit right or still fire OOB in your bolt. KUSA were known for makeing bolts out of spec so that is out of our hands. We are not responsible & will not be held liable for any injuries or death by the use of any of our products. Once products ship it is out of our hands and out of our control we do NOT insure anything unless you request it and pay extra for it. We will not be responsible for lost or stolen parts after they ship! Dont like it pick it up in person or simply dont order. By placing your order you agree to all of these terms!
