    I thought that these would just be another average castle nut but made from aluminum. However once my order arrived in a well packed clear container I could tell there was quality in the machining. The threads were all clean and the anodized finish flawless. I installed it on my buffer tube without any thread lubricant and it spun down and easily torqued up next to my end plate. This is a must have part for any project or store stock AR.
