  1. I like those blocks. btw I made the same mistake you made using the torque wrench and crows foot tool. put the torque wrench at a 90 degree angle with the crows foot or your torque will be too high. I didn't believe it until I saw a video of the issue.

  2. Great video but all I wanted to know how to change the ejection cover AKA dust cover to a custom laser one that has my name on it. You might want to do a video on that. Anyway I have the enough information from your video to change the dust cover. Thank you, please keep up the good work, its people you that save people like me from taking my riffle to a gun smith and spending $$$$. 

  3. I'm not a Gun Smith but I am very familiar with tools as I work on Boeing 737's. I just have to comment on the use of the torque wrench with your barrel nut wrench. You say not to exceed 60 lbs with that setup. Well first the Armalite AR10 says not to exceed 45lbs. Then, improper use of an extension on a torque wrench will definitely cause someone to over torque there barrel nut which could cause later problems. I'm not saying you my not already know this but your video could cause someone some expensive issues later down the road. Proper use of a torque wrench when using the barrel nut wrench that's in the video @ the 7min mark, would be to place it at a 90deg from the handle to not over torque. If you use it off the head straight as you did you have to add the inches of the lever increase from center to centers. 

    Here's the formula:     wrench setting= desired torque x wrench length /
                                                                  (wrench length + extension length)

       Let say your torque wrench is 18 inches, the proper torque of barrel nut is 45lbs, and the barrel nut wrench center to center looks to be about 2.5 inches.  

                          Actual torque applied = 45 x 18 / (18 + 2.5)
                                                             = 45 x 18 / 20.5
                          torque wrench setting = 39.5 lbs

    Ok, so that's only looks like a few lbs in that formula but if you set the torque wrench to 60 lbs per your video on the high side to be safe like most go with then you are now applying 68.5lbs to the barrel nut that's 23.5lbs over torque to the barrel nut and I think that could cause someone some issues down the road.

    I'm not trying to step on toes here and I just want to say I like your Videos they do have good info. I plan on purchasing this hand rail for my new AR. I just wanted to make a comment cause I saw something that could lead to a problem.

    Thank you for your Videos and good Shootin!!

  4. Basic knowledge is that if you do not know how to work on an AR style rifle then you should take it to someone who does. That being said, I did learn on my own how to build a complete AR-15 5.56 and did it in about 15mins once I had every piece acquired. It is not difficult, but it does take patience and common sense as well as the proper tools. Thanks for the video and instruction sir. I am sure that someone has learned from it. Be safe and shoot safe and responsibly.

  5. I wish my delta ring was that easy to push. It took everything I had on my M&P 10. Thanks for the video.

    Waiting on my tools and material to get here. Also waiting on my bank to fill back up again. Lol This is an expensive hobby.
