Good initial impression, but disappointed

Pros: Cheap, nice exterior finish, 7075
<br>In my personal experience, the interior of the tube had gouging or pitting. Came from the factory this way since it comes in a sealed bag.

FAST shipping

Good quality part at a great price. You cannot beat PA for quick shipping.
<br>I had the tube in less than 48 hours, Houston to Boston for under $3

Inexpensive but good

I bought this receiver extension tube because: #1 I have an Anderson lower and thought it would match nicely (it does). #2 It is the only cheap receiver extension I found that is 7075-T6 aluminum and #3 it was on sale. Impressed with the finish, fit and overall quality for the price.

Glad I received this extension

Flawless coating, threaded right into my receiver. The powdercoat on the inside is blemish free. This buffer tube would be a good buy at twice the price

Good Quality

This is a basic, mil spec tube. It's well made. The threads are cut well, the finish is nice and it's sturdy. Installed with no issues. Works as it should. Would buy again.

The one I bought is perfect

With fit and finish this good, I can't understand how more expensive buffer tubes exist. Flawless threads and coated evenly inside and out. Runs quitetly with the correct spring
