Troy TRX Extreme 308 Rail Install on S&W M&P10
I run through the install of the Troy rail for AR10 type rifles, in this case a DPMS low profile version that fits the Smith & Wesson M&P 10

  1. Like your vid. FYI on the torque range per the USMC maintenance pecs 30-80 ft-lbs, just helping my dyi shooting brothers out.
    Thanks for the video, Shoot safe, shoot often, and keep it in the 10 ring. ( And for Marines, 5 ring ).
    Take care, and God Bless

  2. So, guessing that your torque wrench measures 18" from handle pin to the center of the square drive, and the barrel nut wrench measures 3" from the center of the barrel nut to the square socket…40 ft/lb. on the setting would equal 1/6th ft/lb. more torque, i.e. 46.66 ft/lb.

  3. Here is an excerpt from a Practical Machinist forum thread post, by Robert Campbell Jr.:

    "Similar extensions used to be available for torquewrenches, along with a little compensation chart. Probably still are. 

    Any extension can be compensated for with a simple calculation. With a 6" extension, parallel to a torque wrench with 12" between the handle pin and the center of the drive square, the torque value set on your clicker wrench should be reduced by 1/3, the same ratio of the extension over the standardwrench. 120 ft. pounds becoming 80 ft. pounds. 

    You've just created a torque wrench where foot pounds have become "foot and a half" pounds. By the way, extensions on the handle of course have no bearing on when the "click" will occur, it will be the same with longer arc/less pressure but the wrench won't know it, except for the quite probable disabling of the function of the handle pin, where the handle sleeve should never come into contact with the body of the wrench, changes the "12" length."

  4. good video of a T shirt, fast forwarding at parts that are important and mumbling audio. just delete it… so others can search troy and m & p 10 and find a good instruction video

  5. Thanks, good video but you used the vise block incorrectly, the clear pieces are only to hold the black blocks from falling off of your upper receiver. I bought the Trx rail because of how good it looked on your rifle.

  6. Thanks for the informative video. Have much fun with my Colt M4, but my son's MP15 shoot more accurately out of the box, Hundreds of dollars later and they both shoot suburb. I am looking froward to the MP10.
