Quoted:
How does it confront two issues: inadvertently popping open from gas pressure, and wearing out the charging handle latch pocket in the upper reciever? I've never heard of the handle popping open from gas pressure. What else is going on to cause this? Is it a combo of pressure and worn out pocket and/or latch? Also, I assume this is only for the ar15, and not MaTen and other 308 receivers? |

how does this differ from Sintercore's Tripwire? http://sintercore.com/wp-content/uploads/2014/07/standaloneSlider.jpg Sinter core uses a 3d printed polymer latch if that matters. |

I think the Renegade uses a sort of flat spring only (with a little synthetic bushing). I don't recall there being even a roll pin pivot point on the Renegade. Quoted:

Isn't SLR Rifleworks offering similar too ? I think the Renegade uses a sort of flat spring only (with a little synthetic bushing). I don't recall there being even a roll pin pivot point on the Renegade. It uses a ball bearing tensioned with a flat spring. |

Further production is halted until we determine patent status of MEGA Arms’ just-released charging handle with identical design It will be interesting to see how this turns out. I was excited when I heard about the SLR but then read that it likes to eat away material on the upper.  Let's hope Mega and Sintercore can get this sorted out.

They said it would be cheaper than the rest of the ambi charging handles, and the cheapest I can think of is the BCM charging handle at $35. Quoted:

Any word on MSRP? They said it would be cheaper than the rest of the ambi charging handles, and the cheapest I can think of is the BCM charging handle at $35. For the BCM ambi? msrp is 70... |

How exactly does it work? Does the latch actually lift up and unhook from the upper receiver or does it just slide over the charging handle latch tab when it's pulled back?
The pictures make it look like the latch doesn't lock in like a standard one. Look at the latch on the Noveske Raptor below and compare it to the Mega latch picture in the OP. The picture showing the bottom of the Mega charging handle shows the latch having a shallow angle on the hook compared to the 90 degree angle on the raptor.

But if the tension is wrong, it's going to not lock in when shooting if too loose, or cause premature wear to the receiver catch similar to the SLR Renegade if too tight |

But if the tension is wrong, it's going to not lock in when shooting if too loose, or cause premature wear to the receiver catch similar to the SLR Renegade if too tight In hardened steel (as in a steel upper) this would probably work a lot better, but with aluminum you have that delicate balance, and you have to worry about wearing out the aluminum if you are too tight or cycle it too many times. Once you round out the latch pocket corners, that changes the balance of spring pressure required to keep the handle locked. It seems like one part has to be sacrificial and wear prone, either the upper or the latch, and in either case you have replaced a system that doesn't wear out with one that needs maintenance. |

I wonder how it would do in combat. Has it been extensively tested? I'd hate to have the charging handle rattling around while you're running around trying not to get your dick shot off. If it's combat ready, watch out BCM/VLTOR & RAPTOR. Even plain old milspec CH's have a decent bit of play around the latch area, and it varies with the tolerances on aftermarket CH's. Regardless, the CH should stay in position as long as your bolt is forward. |
| I wonder how this will pan out between Metga Arms and Sintercore? It really seems like they both designed an almost identical product at similar times. I have a Sintercore charging handle from the 1st batch and glad I didn't hold off for reviews before locking my order in. |

I'm sure Mega has done their fair share of R&D on this one. They are a top notch manufacturer. I'm sure it's legit and won't cause premature wear on the upper.  I respect Mega a lot, but after the RAM paint washed off the F117 in the rain, and the F35 can't run if the fuel sits in the tank in the sun because it's "too warm", well...trust but verify. Can you show us this alleged R&D? Can Mega? I'm not asking for the moon, I just want pictures of an upper with "X" number of cycles on it or something. Trust but verify, no disrespect intended. |

Uppers are cheap, charging handles are cheap, I'm willing to do the R&D for them.
