Recoil looks fairly stout in this video, the rifle’s rocking that guy around pretty good. A lot more than the dude with the bitchin’ mustache in the F/A Raptor video, anyway. For the life of me, I can never remember his name, but I’ll never forget that ridiculous mustache.

The MCX has a longer receiver life than a typical AR, all the wear points are s7 tool steel and on an AR they’re 7075 aluminum. Using 7075 for an MCX upper of a scar upper would add $1500 to the price simply because of the waste, shipping expense(heavy blocks vs hollow extrusions) longer machine time, more cutting wear. For absolutely NO benefit. Literally none. I have worked in machine shops, managed one. I’m not an engineer but I definitely understand that side of the house. You don’t know why what you’re asking is a terrible idea. You don’t understand what makes 7075 the industry standard. You just want it because you’ve been conditioned to want it. |

Actual manufacturing is super cool to me. I did a little bit of work with solidworks, some 3d printing and almost got a product into production. Having actual professional insight to manufacturing is like me being a kid in a candy shop. Thanks for the info! |

Sorry if I come across offensive, but how do you know that I don’t understand what makes 7075 the industry standard? I do know how to read and do my research. I was a cop 32 years and recently retired and still in the military reserves, so I have a good understanding when it comes to using weapons under harsh conditions. I also had an MCX for awhile and I did notice that the upper would damage easier (scratching & gouging) than my other AR15’s and was probably due to the softer aluminum. I really don’t think that it would cost $1500.00 more to use 7075 VS 6061 and the MCX upper isn’t that much longer than a mil-spec upper. They use 7075 in all their other lines. |

It’s not that is longer it’s that it’s designed for an extrusion rather than a block of billet or forging. Scratching and gouging are cosmetic. Wear surfaces are what counts. Cam path, charging handle lugs, fees ramp. They’re all steel in the MCX. Vs an AR 7075 upper you can expect the charging handle lugs to wear out between 15-20k rounds. Cam path is between 25-30 and that’s end of life for the upper receiver. The MCX has a theoretical infinite upper receiver life because tho use steel inserts will outlast the aluminum but if they ever do get damaged, they’re replaceable. |

Hopefully Sig will offer spare receivers for the Raptor like they do for the MCX. |

MCX uppers are extruded and the AR uppers are forged. |

I’ll wait for the blah blah blah all action I’ve seen response. It has nothing to do with understanding metals. Has to do with actually using them in harsh environments and seeing the wear and tear. |

You can buy a Zev forged 7075 T6 upper receiver for $120. I don't see how that $1500 dollar number tracks with that? I also don't think lessening external wear such as loss of coatings, scratching, and gouging can be classified as Zero benefit. Keeping a weapon's exterior burr free seems like a good goal. Even small superficial cuts can get infected if some poor guy in deployed in a swamp for weeks or months. I've been cut on burred aluminum before, it wasn't a big deal, and it wasn't on a weapon, but this discussion did remind me of it. |

The Zev listing I was looking at says it was forged. Is it actually not? https://aimsurplus.com/zev-technologies-forged-ar-15-upper-receiver/ But what about this primary weapons systems upper receiver then? It's $200 and says that it's Machined from Forged 7075 Aluminum https://vtsupply-com.3dcartstores.com/Bootleg-Stripped-7075-Forged-AR15-Upper-Receiver-Primary-Weapons-No-Forward-Assist_p_1274.html |

I know I’m late to the party but I 100% want a Spear in .308! Only recently have I become interested in the MCX and yesterday began thinking, “hmmm, a 16” .308 and 11.5” 5.56 would be my ideal pair!”. Come to find out, a larger cal MCX is already in development for the .mil. While I’m a big “bang for the buck” guy, I think the MCX Spear is a unique offering and I’d definitely pony up about $3500 for one. As for the Raptor, the video above makes it look absolutely ridiculous given the amount of recoil, but maybe it’s partly the shooter. |

Well it didn’t happen, so hoping that something is going to be revealed at the 2022 Shot Show. Sig apparently won’t be there, but they should have something virtual for all their new releases. |

On Time. On Target.

If you have to ask the price, you can't afford it. :P If the production versions aren't $3500-$4500, I'll be shocked. This is clearly in SR-25 money territory. 277 Fury ammo availability is the elephant in the room. Sig blew it with the 277 Fury Cross, and it's unclear why this is different. |

This thing will be <3500 after pigs can fly, but it’d be amazing if it did. |
