This tube works for ar10 platform rifles. - Wilson Combat Rifle Length Gas Tube

This tube works for AR10 platform rifles. It is a little longer for positive gas transfer, it will solve short stroking problem. If you are one of those complaining that it is too long, you probably shot your rifle with a shorter tube first, and now the carbon fouling is keeping your bolt from closing all the way. You will have to clean the carbon from the bolts staked gas tube for this to fit now. Remove the carbon, and it will fit! Duuhhh!
