pognivet 150 Posted May 23, 2016 I know the Mossberg 500 has an aluminum receiver instead of a steel one, but that the bolt that holds the stock onto the gun is made out of steel. Since the steel in the bolt is tougher than the aluminum alloy they use in the receiver it can bite into the receiver when replacing a stock and strip the threading for the stock bolt. My question is this: Can a replacement aluminum alloy number 7075 bolt be used as the stock bolt instead of the steel one? It feels like they used a steel bolt for a reason. I don't know if any aluminum, even an alloy, can withstand the shock of the blast and also withstand bending in case the stock is knocked against something. I was wondering if anyone more informed had an idea about this? Thanks. Share this post Link to post Share on other sites
