  1. The problem with this is you don't relieve the pressure of the delta ring on the barrel just behind the A2 sight and gas block. Accuracy is going to be limited. I have two AR's I use in training. Both are free floated and shoot holes touching @100 yds. We have bowling pins at that distance suspended by wire. Some students hit the wire on purpose dropping the pin. Wire at 100 yards. Not bad.

  2. great video, straight to the point and very informative. People are dicks and like to talk shit but they are probably licking Cheeto dust of their Dick shaped fingers as they type in the bullshit comments. hopefully they will get ass raped in prison or ran over by a dump truck. Good work brother👍

  3. Thank you for the video, its funny the upper I purchased for my rifle has a qual rail and I want to remove it and put something smooth on it. Thanks again and thanks for the tip on the tool, Off to ebay I go…..

  4. Thanks for the information, I bought this exact rail at Academy a few minutes ago to replace the Magpul moe forend on my M and P 15 I just wish the side rails were replaceable with shorter rails, I might save my cash and get the 12.5 Troy rail

  5. Thanks a mill. I didn't know it wrapped around the handguard cap. I originally put a polymer quadrail that fit under the cap like the glacier guards do, so I was scratching head bc I thought these were same minus the build material.
    Thx again

  6. So ready for my quad rail to be here tomorrow. Put my hand grip on the bottom, tactical flashlight attached on the left side. Red dot tactical scope replaced the factory handle sight. Still a rookie to these AR platforms lots of studying to do but great video! Now I know what to expect tomorrow. Great job!👍

  7. Cool vid.. I got a no-name quad coming for my Stag 2L. I'm pretty stoked about finally having one on my rifle. Like PE said.. just good old fore arm strength. I was a Security policeman in the AF and we had to clean our weapons all the time.
