    This one was in a BCM tube as well.

    Sounds like we suffer from the same affliction.


    Glad it's done. I am content & have piece of mind now it is straight, torqued and staked. I have a start point for info if the nut backs out under use too. I can say with certainly it was torqued to the minimum spec and it was staked. (I read and took serious the thread "Importance of castle nut staking")

    There's no doubt. I've seen them come loose.

    Shorts, quite ingenious method for installing the new receiver extension with one hand! Good for you to get it done to milspec.

    I am curious how you shoot the rifle with one arm, though. Do you use a portable support or special sling arrangement?

    Right now I muscle up and shoulder with my strong hand. I can only take a few consecutive shots before I have to come down, rest my arm and go again (particularly for good shot placement). I do try to take advantage of any rest I can find, be it a post, tree, bench, etc. I can shoot all day from a rest (who can't though right?). I would like to start fiddling with slings and see if I can find a way to make one work for me.

    I'm changing out the grip as well to the more vertical grip of the BCM Gunfighter Mod 1. Hoping it will reduce wrist & forearm fatigue caused by the drastic angle. Also recontoured the barrel to LW configuration and put a hair more weight in the back with the buffer & stock - working on balance. The more I can tailor it to a comfortable fit, the easier it'll be to shoulder it for longer (all that bio-mechanics stuff). I think some stamina and strength will come along with training. It won't be as good as having a support hand, but I can get what I can out of one.

    Well with your determination and innovation I bet you'll come up with something that works well. I suppose too that an AR pistol could be an option as well, though a LW carbine isn't bad as you said. And of course standard pistols would be ideal.

    Good luck in your endeavors!

    I think my husband can feel the pain of the bank account draining from here A Colt Combat Commander is my go to. We'll see how I can develop using the AR15 with time and training. Looking forward to it.

    Thanks for the well-wishes.

    Think about it for a minute, you might come up with something.

    FYI, and If you already know this, 10-22. But, if you used your wrench as shown in the pic, you are actually torquing beyond 40ft.lbs. due to the off-set. It's been a while, but a rough guess is you are actually closer to 50.
    Here's a handy guide: http://cncexpo.com/TorqueAdapter.aspx
    I keep my off-set at 90*, when i can, to save any unnecessary math!
    Colt's torque spec for the castle nut (38-42 ft-lbs) takes into account the use of a tool (i.e., small off-set).

    Shorts should be right on or very close to it with that tool (in that orientation) and 40 ft-lbs dialed into the torque wrench..

    Anyone in the market for a torque wrench, the one used is a CDI 752MFRMHSS. I neither work for them or sell them. Just a satisfied customer who put research into the selection. I hope to add the 2503 to my box next. CDI isn't necessarily cheap but well worth the cost.
