7075 T6 with dry lube inside and out. Compared to most leading manufacturers the threads on this are true milspec and a littler wider then the rest of the tube. Contains 3 drain holes at the bottom. Perfect fit.

LMT makes the best Buffer Tube?


It is a damn nice tube. Precision quality. When running a Silent Capture Spring, I actually prefer a BCM buffer tube. I’ve built 5 lowers with this combo and the fit is perfect plus the tube is a solid black. The LMT typically needs painted and the lip is much bigger than the BCM which I’ve heard can cause an issue where it may need cut down. LMT’s are super hard to find, I think I like the readily available BCM better.
