To avoid diverting the Remington barrel thread I thought it appropriate to start a bullbuppy thread.

Comparing your Remington brrel to my charter arms barrel, IF it were like that in every groove for the full length I would say it looked just like my worthless bullpuppy barrel when I got it.
A machinist friend I was showing it to asked why I had been shooting black powder and not cleaning it.
Thrown to the back of the safe for other reasons, but that is another story.

Glad all of their products are not like that.
