Gauging Interest in Tungsten Slow Fire Bolts

[TheColtCollector]

Any updates? A tungsten bolt for my M11A1 would be great!

I’ve got one posted

 

[Mr. Greg]

Yes. Please send an email to tina@macmachineguns.com and let me know if you want the bolt for the m11/nine or the m11a1/380 and if it’s for a 380 gun, is it a small or large mag well.

I’m a bit confused - is the hybrid project only for the M11s, or for the M10s as well?

Both. Actually all three. The 380, m11/9mm and the m10’s.

Thanks, that post I quoted sounded like it was only for the m11s.

Originally, the CFW bolts were only for the M11 and 380 guns. Before his passing, Vegas SMG was toying with the CFW bolt for the M10 and found it was too heavy and expensive to be practical. In theory, the hybrid bolt will combine both metals so that a M10 slow fire bolt may actually be practical. We'll see...

While I don't own an M10 I'm curious, will the proposed M10 slow fire multi-bolt be offered in 9mm as well as .45 ACP versions? If so, will the 9mm version be able to accommodate dual feed 9mm (e.g., Uzi) magazines?

Yes and Yes. The idea will be that the bolt carrier for the M10 will be a universal part that will work in any M10 regardless of configuration. Then one would purchase the appropriate bolt face - whether steel or tungsten or whatever - to affix to the bolt carrier. We'll be offering bolt faces for all configurations you've mentioned.

Thanks for the quick response.
Best of luck with the project, and I hope that it results in many profitable sales.

The ROF was 805 in an M11/NINE with our hybrid steel/tungsten bolt and 1255 with the OEM steel bolt.

Hi Tina,

Has the 380 hybrid bolt been made? ROF tested?

Thank you.

Not yet. The hybrid project is in it's infancy. The only thing we've created so far is the bolt for the M11/NINE.

I will admit to knowing nothing about machining, but would there be any benefit to making the back half of the bolt tungsten and the bolt face steel? That way if the face wore out, or you want to switch caliber, it would be a cheaper material to repurchase. Is the bolt face easier to machine than the body? Would the bolt carrier weigh too much?

Super excited to hear that this is still a possibility!

From a mechanical operational standpoint, there probably wouldn't be an issue, though ejection might be lame. That said, from a shooter control perspective, some might find accurate, controllable shooting difficult. The "bowling ball in a shoebox effect".
MHO, YMMV, etc.

Let's see it!

We have a new manufacturer on standby, ready to make the bolts, provided we have enough interest. This is the 380 sized 100% tungsten bolt (not the hybrid bolt) that will run in either the M11/NINE or M11A1/380 guns in 9mm. As I stated previously, the previous manufacturer got back to us a couple of months ago with a current quote and it was a lot. I mean A LOT - and we didn't like it at all. We've contacted some other companies and we have one that will make them and they are ready to go. This company sources their tungsten from the Americas. Mostly Canada, but some comes from South America - none of it comes from China. This company will also 100% manufacture them in the USA. These new bolts would be truly American made. This was not the case with the previous bolts and we are proud to say that our PS-W bolts will be made in the USA. At today's pricing we are looking at a retail price of $1225. Like last time, we'll be requiring a 50% non-refundable deposit. I'll be sending emails out this week to those on the wait list to see who is still interested in the bolts at this price. If we can get enough people interested we'll turn them on. So if you are on the wait list, please be on the look out for an email from tina@macmachineguns.com (sometimes my emails end up in the spam folder.) If you'd like to be proactive and shoot me a line of your interest level, that would be great, it'll speed up the process.

 

[MACsAlot]

Hi All, I've emailed everyone one the wait list. If I didn't hear from them the 1st time, I sent a follow up email. This is our last call for tungsten bolts. If you want a bolt and you've not let me know, please check your spam and/or contact me at tina@macmachineguns.com . It looks like we've got the numbers we need and we'll be moving forward with a bolt run. YAY!!! If you want on board and have not talked with me please do so now. We will not be ordering extra bolts and I cannot say if/when we'll be doing additional runs in the future. For those that are in on this run, I'll be sending an email regarding payment terms soon (within the next few days.)

Thanks to all of you for your continued support.

For those following the progress of our PS-W bolt run, I have an update. Earlier this week we received the sample bolt from the new fabricator. It is a thing of beauty. We installed the extractor and rods/spring and took it out to test fire and it ran perfectly - see 1st video. Then the next day, we took it out with the shot timer and shot another video. The ROF in the M11/NINE is 671 with 115 grain 9mm ammo - see 2nd video. We've also run the bolt in the 380 gun, but we don't have shot times on the 380 guns just yet. We'll get video and stats to y'all next week.
First test fire
Test fire with shot timer

We have a few extras, send me an email at: tina@macmachineguns.com for info on purchasing one.

I think that Tom would be proud that you carried on with this.

 

[strobro32]

I got 667 RPM. The neighbor of the Beast.

 

[Mackjack]

Think you can get it to 900 rpm or so with the right spring and buffers in an m11/9?

Great news!
