    Default AR-15 Accu-wedge vs. tensioning takedown pin?

    Brownells lists an adjustable takedown pin that takes out any slack between the upper and lower receiver. (Part number #452-015-105AC.) It's about $24.50 more than an Accu-wedge. Is it worth the extra cash???

    I was wondering the same thing while browsing around the internet the other night. Has anyone here ever compared the two? Are either of the two even worth it?

    I have the JP pin, not worth the money. More of a hassle than its worth. You have to blue loctite it in so it wouldn't loosen up during recoil, but then shims stick to the receiver tabs and have to be knocked out.

    The Accu-wedge thingie is worth it to stop the play between upper and lower, imo.

    Why are you even bothering with putting foreign object into the lower? The play has no effect on accuracy or reliability. What happens if the accuwedge decides to come apart inside the lower?

    I use the Accu Wedge in all my AR rifles.
    I dont like rifles that feel loose or rattle. It doesnt matter if they are designed that way. I dont like it.
    Ive never had an Accu Wedge come loose or even start to wear out .

    By the way, I have your AccuWedge somewhere on my desk. You owe me $3.94 plus interest.

    It is a no-brainer, it takes whatever rattle there might be out. There were probably more mismatch issues with uppers and lowers back in the day when Aldo invented it. I could not imagine an Accuwedge coming apart since all it does is take up space.

    -The play is annoying.

    -Come apart? What are you shooting, a .50 BMG beltfed upper?

    Before I got an accu-wedge I used a pencil eraser, did the same thing, although somewhat less elegantly.

    I used a 1/8" section of boot lace in my M16 when I was on the shooting team to stop the play.

    I'm a big fan of the accu-wedge.. Every AR I have owned got one in it.
