The tool craft bolt I bought works great! However, this review is How ever for the customer service of arm or ally. After purchasing many products from them including a ballistic advantage bolt for ar10 I ran into issues. Said bolt in description was rated to work for 308, 6.5, and another caliber. However due to the fact 6.5 creedmore is more high pressure than .308 the cartridge and with this bolts firing pin hole being to large it caused primers to blank. Upon figuring this out I reached out to arm or ally to receive a refund or at minimum store credit. There response was no. Arm or ally severely disappointed thought you a honest company and recommend you to friends. Will no longer be a customer if problem is not resolved
