Free float handguard tubes allow the barrel to be isolated from pressure that is placed on the handguard, preventing a shift in point of impact when a sling or rest is used. Watch along as Larry Potterfield, Founder and CEO of MidwayUSA, demonstrates the process for installing a free float handguard on an AR rifle.

  1. I truly found this video informative a d a quick overview. I was actually having that same problem with my AR project that I am building. I also have watched all of the other videos and have constantly learned. Is there any particular manufacturer that is preferred for a personal build 

  2. Hi I'm Larry Potterfield, President of the United States of America. I've just pushed the big red button and nuked the Russians back into the Stone Age and that's the way it is.

  3. It funny how many people are viewing this and not getting it. The directions are clear as glass! If you don't get it maybe you sould think about going to a gunsmith, or just replay the video, stop jerkin off and pay attention.

  4. There's only 1 roll pin in the gas block, it holds the gas tube in place and is hollow (like a "c" from the side actually) the taper pins are what your working on. Also there are some manufactures that use hydrolic presses that can and do generate thousands of pounds of force to seat the pins. Another trick is to get a brazing torch from walmart or elsewhere… heat the gas block itself away from the pins then try and drive them out (the metals heat and expand relaxing some pressure on the pins)

  5. steel punches are a must, those taper pins fit EXTREMELY tight. Beat on mine for a while before they slipped. Also make sure your driving them out the correct direction, they are actually cone shaped.

  6. 20 bucks for the barrel wrench from midway, also has several other funtions (castle nut wrench, flash hider/ compensator wrench) a super handy ar tool if you own one.

  7. Using a proper punch will make a huge difference. The point of the nail sits inside the end of the roll pin causing more pressure making it more difficult to push thru. Sometimes sprayin a lubricant nt he pins prior can also help. Caustion tho, that can cause your punch to slip and scratch your finish. Another thing is look at the pins closely and see if it could be easier one direction rather than another.

  8. i couldnt drive out the gas tube roll pins from my AR15, they just would not budge. i didnt use the tool as shown in the video, i used a nail and a hammer….is something odd with my gun or do i really need that tool?

  9. Absolutely – Check out the Daniel Defense M4 RIS II Free Float Tube on our website MidwayUSA.
