Roll Pin Not Included

I wish that I would have read the description more carefully. If I'd known that there was no roll pin included I would not have purchased this.

Not a good one

My rifle length gas tube was a defect? The whole drilled for the pin was off-center and I tried five pins before asking my friend who also builds AR’s to pin my gas block. He also could not, fortunately Brownell has a lifetime guarantee. I have since bought two more of these gas tubes and the pin fit perfectly on the first try this one will be returned.

Would you recommend this? Yes, I would recommend to a friend

Rust issues

Both of these gas tubes came covered with rust... I thought they were stainless steel.

Does not include roll pin

Don't understand why this part is not included. Description should specify this.
