Seems like every single keymod attachment: light mount, and or picatinny rail section has some super soft super cheap star-hex that I either strip out or break the attachment with.
I've stripped out maybe 3-4 so far (not even torquing hard, just on and off a few times) What's up with this cheap shit? Is there a picatinny rail section that mounts up not using this cheap garbage star mount shit? Pretty obvious why .mil will never adopt keymod; it's garbage. Unfortunately I have a few rails with it so I need to make it work for me - hopefully someone has a bomb proof picatinny rail section conversion. |

user error on this one Exactly............ So let me get this straight...........EVERY single keymod item strips or breaks installed by you, but not by 1000s of other people, and its a fault with Keymod? Ive removed my BCM keymod VFG about 40 times in the last month deciding if I want it on there or not, still just as sturdy as day 1. And I just put 400 rounds through the rifle this past Saturday, nothing wiggled loose |

they seem to wiggle loose after about 200 rounds at the range. Quoted:

You're over torquing the screws. they seem to wiggle loose after about 200 rounds at the range. This is why I left Keymod and went with M-LOK. Keymod was horrible the time I used it. I would used: Good parts blue loctite good torque Always came loose eventually. |
I had my BCM offset scout mount come loose after shooting maybe 25 rounds, but then I also did not torque it or loctite it down as I was trying to see if that was the location where I wanted it. Once I knew it was good, I applied loctite and torqued it down and have had zero issues with my KMR-A and BCM offset scout mount. Did you not install the recoil lug either? Some items require the use of one, as it acts as the rearward force so it does not move. Other items, such as my BCM KSM (keymod sling mount) do not require it as it has a "lip" built in that prevents rearward travel.
I am not for or against either keymod or mlok, but either system would have the same issues you describe if they did not have a way to prevent travel forward or rearward, like picatinny has. |

Fixed it for ya. 
Quad Rails never come loose. Go with a quality one (like Daniel Defense) and they are almost as light weight as anything else. If it ain't broke... Quoted:

Your solution is Picatinny Quad Rail.  Fixed it for ya.
Quad Rails never come loose. Go with a quality one (like Daniel Defense) and they are almost as light weight as anything else. If it ain't broke... Funny... My KAC RIS (quad rail) comes loose and wobbles all over the place if you put any sort of pressure on the attached VFG. |

I had a keymod rail for a while but ended up selling it as I got tired of my sling mount coming loose. I cleaned the threads, applied blue thread locker, and properly torqued it down but it still came loose. The day my rifle hit the ground because the sling mount popped off was the day I swore off keymod.
I now prefer a simple quad rail. They aren't the latest and greatest but they damn sure work. |

I've stripped the heads out on about 1/2 the screws on my lasts build. Had some functioning issues and had the gas block off a couple times so I took the rails loose so I could get to the gas block screws easier. Two out of four stripped when trying to take them loose.
I made a couple screws first (ground some grade 8 screw heads down to get a tapered head), then I found these on ebay and bought a couple packs to put away for the future. Hard heads. No issues. http://www.ebay.com/itm/121372036336?_trksid=p2060353.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT |

What sling mount are you using? Any pictures of it? |
