Excellent quality.

Very good quality parts from Expo Arms.
I will be buying a few more for sure.

Unexpectedly good


I just had to say that upon inspection of this new Expo Arms 7075 Mil-Spec 6 position buffer tube has something overlooked in the description. The inside of the bore is coated with a moly dry film lubricant just like Colt and other higher end parts suppliers and manufacturers do. It was a nice surprise. Checked the thread fit in a couple of lowers and it fit as it should. Tried it on a couple different new B5 carbine buttstocks and they feel just right with no rattle. The machine work and finish are very good also. I don’t think a person could go wrong using this buffer tube on any build or keeping a couple around as spares.

Seems perfect

Fit is good, though I didn't measure appears in spec. Threads were clean and straight.

Excellent Buffer Tube

Another fine product from Expo Arms. Buffer tube I received has perfect fit and finish on the outside, but more importantly it has a perfect finish on the inside. No tool marks whatsoever. No "slag" at the bottom and has the dry film lube on the inside. This is a quality buffer tube. Buy with confidence.
