Cool.
Would be great if you could post an update after a few thousand rounds. |

How much?
I have always wanted a way to make ARs shorter. I have a Law, I have SBRs, but never found something worth the price or trouble |

Good deal. Thanks for the insight. I've got one on order and am eager for it to arrive.

The slide weight that's only connection is the gas key concerns me.

Underneath the gas key are cuts where all the interaction occurs. I don't understand how it is supposed to offer any dead blow affect. Is there really any room for it to do so with the whole setup? It really comes across as a carbine weight buffer and super duper heavy spring combination. Not saying it won't work, that kind of combination has worked and can work, just that it's not optimal, if that's what really going on with this new all in one bolt carrying buffer group. |

View Quote I can't really speak for any of that deadblow effect as longevity of use will earn it's weight in gold. It would be cool to be able to remove the weight and change it out as we would see fit. Like changing it to a titanium weight vs tungsten weight, vs aluminum weight or changing out the spring. However I can tell you that it doesn't feel like the springs are heavy at all. It feels maybe a slight amount more heavy than a carbine spring or about the same, with a slight "hump" at the end when charging. Not like a hydraulic buffer "hump" . It's not quite Sprinco white, but it's not even close to Sprinco blue. The feeling kind of reminds me of the Armaspec silent captured springs with less tension than the carbine version. I haven't tried the other springs as I only had the lightest main flat wires installed and also lightest side springs installed. I'm 100% to say that I can't really describe how it feels to charge the system or how the recoil feels. It's not bad by any means. It's different. I haven't had enough time and rounds through it take make a final assessment, hence my first impressions thus far. |

View Quote I mean 35ish rounds isn't a lot but the only issues I had were with Hexmags. I already went into it knowing it wouldn't work though. As to how much it weighs, it's not a lot but it seems to be enough have an effect from the amount of force the weight exerts. I did reach out to EWS and they said it's 4140 chromoly and they wanted to try tungsten because it seemed the most idea but 1. It is brittle during impact and 2. Expensive 3. Hard to machine. |

The kit looks like it's pretty high quality. Have they made any claims about durability/round count testing? I'm pretty impressed with how short it is and it's compatibility with Sig pic rail stocks, etc. Can orders/preorders still be made?

Very interesting.
Interesting about the amount of exhaust ports in the bolt carrier. Because I don't quite understand, can you close the dust cover with this ? Certainly not critical... just curious. |

Certainly not critical... just curious. View Quote You can't right now because they're going to offer their own dust cover eventually. It's to my understanding the rods go right through that area. I'll ask what the idea behind extra ports are. I actually had a chance to shoot this again yesterday because I got my replacement triggers. I had 0 issues with steel or federal xm193 and shot a couple hundred rounds. I brought a lot lightweight ARs with me and this AR had the smallest recoil out of all of the guns I brought, about 1/3 of my MCX Rattler 5.56. It fired between 3-430o'clock and had zero issues. Mind you, still didn't have my handguard or stock on it (all the Sig minimalists are out of stock). I'm very impressed so far and excited to out everything back together. |

He's said the reason why it's taking so long to release for most is because they keep testing and making improvements. I'd rather that then they go the Desert Tech route and release a hot pile. |

I wrote them an email, but haven't got a response. It would be awesome if I could call and talk to a person at EWS about this stuff. Anyway, maybe someone in here knows the answers, or maybe EWS is in here. Here are my questions:
1) Are any of these BCGs in stock at this time? Will the order be fulfilled within 8-10 weeks of order placement, as it says on the site, or could it take longer? 2) Will the system work with the Q Honey Badger 7" 300 Blackout barrel with pistol length gas tube and adjustable gas block assembly, or do you suspect it would need a different gas "Pig Tail" tube for reliable tuning? 3) I noticed the BCG doesn't work with standard AR dust covers. Is an ejection port dust cover being developed that will work in conjunction with the EWS BCG? |

I was one of the first pre-orders when the website wasn't being offered to the public. 2. I asked them this question previously. 300 BLK pistol needs an adjustable gas block or gas key + special springs. Essentially, the same one mine is set up with. It should also function with 7.62x39 and mid length setups as well. 3. They told me they were developing a specific polymer or aluminum dust cover, but they wanted to fulfill shipments first. There's not a lot of R&D with a dust cover in comparison to a bolt carrier, being that it either works or doesn't work with 1 carrier (EWS) |

View Quote It's just a separate weight on the carrier that is still moving after the forward half of the carrier/bolt goes into battery, so bolt bounce has to work against that as well as the energy transferred into the carrier once the weight impacts it. Think the tungsten fillings in an H&K bolt carrier, there's not a lot of space for them to shift around in, either. |

I just ordered one of those JMAC folding stocks for one of my setups (14.5 p/w in OP). Should be in (hopefully) by next week. If so, I'll be recording some video of the system soon.

Thanks for making this post and being a guinea pig. I'm very interested. Although I feel like the benefits of this will not really shine until we see more options in terms of collapsible braces. An mp5 style brace with carbon fiber rods could be lightweight and allow for an ar pistol configured with one of these to go ultra compact..

View Quote The folding stock and braces are a cool feature and is why I purchased it to begin with. However, now that I've used this, I would almost rather have as a replacement over a traditional carrier specifically because of recoil impulse. It is that good. |

Pretty innovative. Just when yout think the AR has reached its pinnacle, someone pushes the envelope further.

Quoted: Pretty innovative. Just when yout think the AR has reached its pinnacle, someone pushes the envelope further. View Quote Yes and no. This design borrows a lot from the Sig MPX/MCX and the FN SCAR. It is cool that they adapted those design principles for the AR though. The first time I took apart my MPX I thought it would be cool if someone did this for an AR. Thanks to the OP for all the info. I was looking at these the other day while planning a short AR build. The receiver extension, buffer and spring has always been the Achilles heal of the AR when it comes to making them shorter. Maxim has solved parts of this with their stock/buffer combo but its still hanging out there. Nothing like a true folder to really shorten things up. Good to know about the dust cover. My build is a slick side upper without so it would be perfect for that. |

The MCX 2 spring design sits above the carrier, where this has 3 springs and sits behind and goes through he inside of the carrier. I don't know anything about the scar system. I would say MCX has harsher recoil by about 1.5-2x this, which isn't much given that it's a nice shooting platform. I get my new stock Thursday so I'm excited to take pics once installed |

What’s the price point on one of these?
This is exciting for sure, keep us updated. |

Not knowing exactly how the mechanics work, but would a piston conversion kit work with this? I.e. an oprod and bolt on gas key replacement. Or does it “require” gas to operate the mechanism?
Piston would get rid of burnt debris on the lower and bolt assembly area, dramatically improving life and cleaning interval since you could grease the wear surfaces and it stays put. Thats what I do with my Osprey Pistons with 5.45 corrosive. Also eliminates 100% of gas cloud near your face when shooting suppressed. Looks very clever and unique, nice work Evolving the platform! |

I have the second one I purchased just lying there collecting dirt. I'm thinking of putting an Adam Arms strike key there with 180k psi and 170k psi McMaster screws (with those zinc plating) in so it doesn't shear. And then I'm thinking of having Superlative Arms make me a custom op rod that's flat to strike the surface. I'm already having them make me a pistol op rod for a pistol build. Problem with doing this, is if it fails it is a potential if being a $600 mistake (could ruin upper, EWS buffer, op rod, and strike key). I don't mind being a guinea pig if y'all don't mind fronting the difference, lol. |

The short carrier may dig into the upper and bind on the springs. If they say not to use unrestricted pistol or carbine gas due to potential damage then a piston is probably out too. |

*UPDATE: 07.03.2020*
Before today I only had a couple of hundred rounds through this. Now I have about 300 or 400 or so. It was around 3:00 for ejection and I would have felt better being at around 400ish, but I didn't have the tools to adjust the gas with me. The hogue grip was weird for me and I will probably replace for a more vertical grip because of the 8" stock. I don't do videos often and my first attempt I forgot to hit record so you didn't see the full extent of 150ish rounds. I understand I am wordy and talk a lot so you don't need to remind me of that or the fact that I say "uhm" a lot. Failed To Load Title |
