AR Upper/Lower Receiver play.

Oh so now you think an AR-15 is considered a precision rifle from the factory without being reworked by a qualified armorer? Yes it does not position anything upward it positions it together. First of all you need to remember the planet is a sphere. What is up to you here is down to somebody in Australia so the terms up and down are completely meaningless but gravity is the most constant force in the physical universe. So where is your documentation on rifles that have play with aftermarket fixes? Apparently you are just opposed to the idea that I have improved one of my rifles so inexpensively. There is no way possible take a dial indicator to an assembled rifle. The accuracy of the rifle is solely determined by the upper in an AR platform I would think you would know that. The play between the upper and lower was merely an annoyance it does not affect accuracy in any way. Flat feeler gauges and wire style gauges is how you check for what you're talking about. Explain to me how you set a rifle up in a jig and rotate it 360° in all three dimensions with a dial indicator on it. Obviously you've never worked in any type of machine shop. Yes when my upper and lower are jam together tight and held there by the zip ties the relationship on the front pivot pin and the rear takedown pin is the same every time, much more so that without the zip ties. As far as competition goes that it is much more determined by the skill of the shooter be his rifle tight, have .004 or even up to .012 the mil spec requirement. I'm sure a U.S.Navy SEAL sniper could out shoot both of us regardless of what piece of junk he was shooting and regardless of what a fine rifle we had. You live in a world of theory and documentation.

I think you need to fly to New Orleans because you are extremely afraid of voodoo. When you arrive let me know I know a lady there that can remove the curse from you

You are like a teenager that every time their parents catch them doing something they try and change the subject. You can call me dad if you like

I thank you Mistwolf and someguy 2008 for recognizing the problem is sloppy tolerances in the production but as we all know most AR15 have it. That's why I have three LMT's with no zip ties. If anyone needs zip ties send me a self-addressed stamped envelope and I'll send you a few of them along with instructions, probably easier to just stop by your local auto parts store though.

BTW does anyone know why JP Enterprises quit making a rear takedown tensioning pin they do not even know.

Exactly and the zip ties just eliminate the annoying rattle and do not degrade accuracy in any way, and the zip ties bother me less than the rattle did. Now it's rattle free and just as accurate. Now the rattle that was just in my brain is nowhere, it is gone.

Yes sir. Hey gunny if I still lived in Saint Gabriel I run over for a cup. I had a 45 series 70 Colt stolen out of my pickup truck in Denham Springs about 30 years ago where everybody used to party on the Amite river under the Florida Boulevard Bridge..
