Anyone else see this? I've been following since conception on Instagram and pre-orders started yesterday. Bottom is links to them working. I pre-ordered 2. Doesn't have FA cuts or dust cover cutout, but I guess they will be releasing a dust cover that works with this I believe they said (somewhere in their Instagram commments) the entire system will weigh around 8oz.Whats the hive think?

It looks like a very cool idea. The catch will be durability and reliability. I definitely see using one of these on a braced pistol if they turn out to be reliable.

Thats very cool, thanks for sharing.
Hopefully this is the beginning of a glorious era of folding stock DI AR's. Assuming these work, I'll absolutely be snagging one for a pistol build or two. Curious what the cyclic rate would be in FA. |

Looks cool, and any kind of innovation of the platform is nice to see. Not sure it fills a need for me personally, but I still kinda want one.

This looks good, I am sure they can get at least $200 for the system?
Seems basically like most other twin recoil spring assemblies but also curious as to their warranty terms/durability |

Very cool idea. If it’s reliable it will be the “killer app” for AR pistols and SBRs. Can’t cost 2 grand though.
ETA: price looks decent actually, but people will want it with buffer tube threads to use crap like the law tactical folder. |

I'm sure however they'll come eventually. If I were them I would have also included an RCA adjustable gas key for that price. It's kind of rough, but also look at competing systems. |

I'm guessing this will be more sensitive to ammo, dirt and temperature changes due to relying more on spring weight.
If it works reliably it makes a lot of sense. No need for a buffer tube. Even if your stock breaks off the weapon will still operate. The price is ridiculous though, IMO. |

Note that the requirements state you must use it with an adjustable gas block, so this isn't a drop-in solution.

Looks interesting. As others have mentioned, the Dead Foot Arms system, while a little pricy at around $400-$450 works like a Swiss watch. And while it is a proprietary bolt and spring system, it has not needed a specific gas tube, adj. gas block for the various gas system lengths. And it only takes a couple of minutes to revert back to the standard buffer and spring assembly.
Will be watching this new set up with an eye to reviews and its longevity/durability. Not affiliated with Dead Foot other than as a satisfied customer, and we did sell a fair number of them when I had my own shop. |

Whereas the Evolution system should allow a folding mechanism almost as short and thin as found on the MCX. |

Quote HistoryQuoted: No, I didn't really like the looks of the Dead Foot. I'm sure it works fine, but it's pretty hideous, and you're stuck with a ~2" buffer tube plus a very wide footprint when folded: https://spotterup.com/wp-content/uploads/2017/01/Screen-Shot-2017-01-22-at-6.33.19-PM-750x400.png Whereas the Evolution system should allow a folding mechanism almost as short and thin as found on the MCX. |

Interesting that it states a pigtail gas tube MUST be used with the pistol gas length and that ALL must use an adjustable gas block. Guess gas is drastically reduced, I wonder how these will run when the gun gets dirty? Would also think these will be very ammo sensitive in our shoots quality ammo and some of the low pressure stuff.

This is like a chopped ~8oz BCG + 0 Buffer So by reducing weight by 49%, you need to reduce gas by a large amount otherwise it's going to be super overgassed. |

If the ROF is 900 RPM, the bolt is likely extracting and slamming forward with comparable energy to a regular setup and a carbine length gas system. Looking at this thing, I would be surprised if ROF is 1000-1200rpm. |

Not possible. The part of the bolt that would take the serrations is gone. The dust cover indent can't be milled out because that is where one of the twin springs goes. I think this would pair well with a slickside upper receiver. |

I think it would be badass to combine this with an otherwise stock A1 and modify the stock to fold to the side like an AR180.
