The perfect fit for my rosco barrel - Rosco Manufacturing Melonite Gas Tube

I recently got a great deal on a Rosco barrel from Opticsplanet.com. Unfortunately, the gas tube was not included with the barrel. I think Rosco should include the gas tube and pin with any barrel they sell. It was an inconvenience having to order one and wait for it to arrive after I had already received the barrel. The other thing that was a little annoying is that the Rosco gas tube was more expensive than many other legitimate manufacturers. That being said, the tube looks to be well made.
