I intended to say that the gas tube should fit an AR15. Sorry for the typo.

The gas tube was too short for my AR10. It should fit an AR10 OK. I would order it again if I had the rifle for it as I shoot reloads and factory bullets.

Thanks for the info. I ordered the adj. gas tube without doing enough research. I thought it would be better idea than an adj. gas block. I will know in 2 days if I need to send it back.

Brownells has a gas tube with a small valve to adjust the amount of gas flow. My question is, can I use this on my AR-10? Are AR-15 and AR-10 gas tubes the same length and diameter?
