AR15 Upper Build Gas Tube

Love it, simple and to the POINT! No less, no more!

So TIRED of Gun-tubers chit-chatting for over 5-10 mins BEFORE they ever go into the ORIGINAL discussion point of the video lol!

Thank you!!! I built an AR upper but purchased a bushmaster rifle barrel with the A2 front sight already installed. (No Gas Tube) I had manipulated the gas tube I bought for it a dozen different ways trying to get it to work and was about to remove the front sight/gas block until I decided to search good ole pewtube for a video. I had not tried to do it the way you have shown in the video. You saved me time and money because I would have probably left off the A2 sight and bought a free float rail since it was already broken down that far. Once again thank you.

What happens if you put the gas tube on backwards with the dog leg on the wrong side?

Hi live, my names steve im installing a new m4 barrel I just purchased for a Olympic Arms for my M4 problem im having im doing everything you show but when I slide gas tube into front site im a1/8 off from the whole and cant get the tube to move forward anymore. note I did have to clean the front site gas tube hole out because it had a white film on the barrel  I guess from being in storage . if I remove barrel from receiver I can get the tube into the front site with no problems any suggestions would help me thank you … steve
