I purchased a gas block online and had reliability issues. I had purchased a barrel from Spinta Precision so I called them to see what I could do. I sent my upper to them and they determined I had purchased a bad gas block. They installed their gas block and solved the problem. Spinta Precision are great to work with and they make quality products!
