Absolutely gutter trash! stay away! - JE Machine Tech .223 A2 Buffer Tube Combo, 5 Pieces

DO NOT BUY THIS!!!! The rifle buffer tube threads are cut out of spec. There is no smooth are left at the end to properly engage the buffer retainer pin. The threads going all the way to the end, means the buffer retainer is held too low to keep the buffer feom flying out of the buffer tube whenever you open up the rifle! The buffer itself is also completely out of spec. The head of the buffer, instead of being cut with 90° angles for the face, is rounded on the edges! This further eliminates needed area for the already too low sitting buffer retaining pin. This kit therefore is unusable junk. I guess I will see how Optics planet handles returns. And my customer will wait longer while I order a 2nd round of parts.
