CiTY HuNTeR's Review of JE Machine Tech AR-15/AR10 Mil-Spec 6-Position Receiver Extension Buffer Tube

All mil-spec are including materials. Only 7075 aluminum can be called mil-spec.
This tube is only 6061, an aluminum alloy that is much softer than what mil-spec tube uses.
I'd not suggest anyone to use 6061 material on the buffer tube.
Would Recommend: No
