AR Buffer
I purchased this because Im building yet another AR. This buffet is heavy duty as advertised. The thread pattern is a few mm longer than my other buffers. I was trying to install a Phase 5 buffer sling attachment but my other buffers didn't have enough threads. This one does. I love it. It's heavy and looks great. Yes I will purchase another one.

Great Buiffer
I found the buffers I was looking for to build 3 AR-15 style rifles through Delta Team Tactical. I was driven to purchase them strictly by the low price, since I have no experience building rifles. These worked perfectly. They were so simple to install, a rookie could do it without hurting himself or damaging his equipment. I'll never have to go anywhere else when purchasing buffer tubes. This is the place I will always go to.

Great Product for the Price!
I've used many buffer tubes from many different companies and these are no different from the most expensive tubes I have. For the price you really can't go wrong
