Bolt Group Buy - Possible?

[Nukes]

Will these bolts come with the associated small parts and springs?

[Tedward]

I would be interested in getting one complete bolt or BCG if at a reasonable price. Sorry if I missed it, but is this going to be a group or individual order?

It will be an individual orders from a supplier he will be providing a bulk quantity to. It will also be a Forum Price so he might have a code to use to get the better price. I'll post that info or the supplier will once that time comes along with the exact cost to include all of the shipping and processing fee's.

Small parts and springs?

[Dan]

I wish I had the machine shop and the know how to make these tings myself. One day, one day...

Small parts and springs?

If your refering to the bolt, it will be completed with gas rings and extractor attached. I was talking to him about using McFarland 1 piece gas rings for better seal. http://www.midwayusa.com/product/163933/...iece-ar-15. In the past we discussed people had poor cycling complaining about the BCG and it was all 3 of the gas rings were lined up. This removes that from the equation.

If you get a BCG, it will have the gas key, firing pin, cam pin and firing pin retainer ect...

There is way more than needing a machine shop. The engineering alone is a very limited capacity skill set in the marketplace. As far as manufacturing goes, there are significant aspects of cutting certain portions of the bolt that aren't a simple operation, like the firing pin channel. Then you have heat-treating, coating or surface treating, and QC testing compliance. It is very easy to screw up the heat-treating. Parkerizing improperly can ruin a part, as can nitrocarburizing. There are so many things that can go wrong outside of the machining alone, which is why bolts are a major hang-up.

That's not even taking the extractor into consideration, let alone correct springs and sub-components. There is nothing really simple and straightforward about manufacturing such a small part, that is required to articulate with another part, and withstand continuous explosive shock force pressures.

Multi-million dollar setup and years of experience to make a $65 part. Mass production and a large buyer's on a daily bases. That's why we were lucky getting his help.

Lol, way to crush a guys dreams...

Yes, back to woodworking :-)

If you own and run a successful machine shop in today's marketplace, your machines will be running full-time. If you don't do it successfully, someone else will be owning and running them full-time after you opt out or are displaced.

Machine time is one of the highest demand markets in the world, and the US has been at the forefront of machine-making, machining, and innovation with regard to new technology. We are also the world's largest exporter and importer. With the retiring machinists and foremen in the industry, there is high-demand for trained machinists and computer drafters. You will find job openings all over the Nation if you have even the beginner-level skills in that profession.

The firearms industry has seen unprecedented growth over the last decade, and it has shifted from old technology and hand-fitting, to CNC machining, pre-tested parts articulation in 3D animation and virtual stressing, as well as more and more automation, higher standards of QC/QA with ISO-9000 series compliance, and more opportunities for customer knowledge about the product. This thread is an example of that.

When would you ever have thought about being involved in the development of a critical part for your rifle, which you can easily assemble at home because of its modular design? Conversely, be aware that there are well over a decade of lessons learned with the Grendel bolt and extractor, and many here are expecting those lessons to materialize without issue in this group buy.

Spoke to Maxim tonight. We'll 9:00pm in VA.

Bolts are going out for heat treating then will return for hard turning then ready for finishing. The other party who is on this forum and will reply some day soon I hope, wants to put the finish on them whether its Parkerized, Black Phosphate, Black Nitride but hopefully NiB-X(Nickle Boron). JP Rifles uses SAE 9310 nickel-chromium-molybdenum steel. What ever that is but the finish cleans up nice....

Maxim also did confirm he has all the small parts available but they need assembled after they are finished.

So he can do it any way it needs done but will figure out the technicalities after he does his machining process.

[Walter]

I vote for Ni-X. I would like to see a complete carrier that way. I need two and a spare. Tedward do you live in north Va? If you we should go shooting some time.

[dmsims21]

I am game for any finish, provided it doesn't drive up the cost too much. I don't want a $200 BCG

[LRRPF52]

Nitrided would be better than NiB or parkerized, as long as it's done right and doesn't make the part too brittle.

[peligro113]

I'm fine with any finish as long as the bolt doesn't end up costing $100.

[cory]

I'm fine with any finish as long as the bolt doesn't end up costing $100.

I'd prefer the Nitrided, but ultimately I'm with peligro113 on this.

[georgepugh]

Now what do we have to do at our end?

[Dan]

I'm not picky, I just want a quality bolt.
