Question On Gas System?

[recon]

Okay what makes your new type for the M16 better than Robinson Arms M96? I ask this because Alex is really pursuing the Military on his rifle!

[KurtsKustom]

It's not a completely new system, & logistics favor 90% of the parts that are already in the pipeline. Thx.

[KurtsKustom]

That's it. I'm pulling this down/off. I've already been w/Ryan@RA. Their unit is too heavy. I'm not getting into some kind of pissing match, not again. I'm taking my little red pocket book and going home. Thx.

[recon]

So your not pursuing your system anymore? :(

[KurtsKustom]

No, I'm just taking it in-house. No further information is available at this time. I'll get a video of me shooting it up in the air like a happy Iraqui when it works. Thx.

[recon]

Did I cause this? To many questions? :(

[KurtsKustom]

It's not a question of being better (that question's already been answered). It's just different. I am producing it. I'm just not opening it up to discussion of same here for all to see. I know what I've got. Pics will stay on my website. In regard to gov't work, I've got an entirely new product to introduce to the military, while this particular upgrade in the evo of the 16 will remain a quiet revolution. Let's move forward, not backwards. Thx.

It's cool, man. I like cool runnings. You just gotta know me. I kick it back here at the Swamp when my brain works overtime. I'm trying to get RJ over here, but it's too close to the holidaze. I'm M17S'n it this week. Took off Tuesday for requisite Christmas shopping with the SO. We're done. Now it's on to business.

[recon]

Okay! ;) You have some really great ideas Kurt! Very good! ;)

[KurtsKustom]

I'm always tryin'! Thx.

[recon]

I use to have a FNC! Wish I still had that one or a few for that matter! Anyway that gas system on that rifle was fantastic! Why didn't the US adopt that rifle?

[KurtsKustom]

I was shopping for a new carbine circa 1980. The FNC was high on the list, but reports were coming in that the FNC was somewhat 'fragile'. This, whether real or imagined, set me off on another course (Daewoo). The Koreans got it right with the MAX series, another M16/AK hybrid, but I still longed for a 'Fancy', which is what we dubbed the FNC. The current M16 gas system dates back to the 40's, and with the reports we're seeing now, I'm right on track. Thx.

[recon]

Cool! Those Daewoo's are nice rifles! Aren't parts hard to get?

[KurtsKustom]

I don't worry about parts. I make them if I have to. I'm a tool & die guy. Often, there's more than one way to arrive at a solution. You just have to keep an open (and hungry) mind. If parts aren't available, it's political.

[KurtsKustom]

The heart of my gas system!

[recon]

[recon]

So anything new on this?

[KurtsKustom]

Still waiting for barrels. I'd like to get some mid-length 1/7's to play with too! Thx.

[argwarrior]

All I can say is, if you build it they will come. Or, at least I will... and the other people lurking about here who have been lusting after a better gas system for our AR's.

I hate scrubbing the baked-on crud off of AR bolt carriers and bolts.

[KurtsKustom]

Koming soon! From the HK website:
Internally the XM8 employs a combat-proven robust rotary locking bolt system that functions and fieldstrips like that used in the current M16 rifle and M4 carbine. However this bolt is powered by a unique gas operating system that employs a user removable gas piston and pusher rod to operate the mechanism. Unlike the current M4/M16 direct gas system with gas tube, the XM8 gas system does not introduce propellant gases and the associated carbon fouling back into the weapon’s receiver during firing. This greatly increases the reliability of the XM8 while at same time reducing operator cleaning time by as much as 70%. This system also allows the weapon to fire more than 15,000 rounds without lubrication or cleaning in even the worst operational environments

So you see, I'm cutting edge. Look for my M5 system soon. Thx!

[recon]

This really some neat info here! Can't wait Kurt! I for one will be your first customer! :D

[KurtsKustom]

While waiting for my M/L barrels from RRA, I'm going to fit up an M4 barrel. Thx.

[KurtsKustom]

Whaddyaknow, it works like a charm! Thx.

[recon]

So are you going to test it?

[KurtsKustom]

Yes. I was banging away last evening. I was losing light, but a 5-slot A2TB was breaking up flash. Next up is mounting the upper for FA testing. Pics later. Thx.

Standard diameter FF handguards?
http://www.kurtskustomfirearms.citymax.com/i/section_29585/M9Karbine_System.jpg

[recon]

Hell yeah!!! Looks like the piston is longer! :cool:

[KurtsKustom]

I'm in 2" HG's. The one shown above is one of mine I cranked out for this project. Carbon fiber tubes are planned for this product (EvoM9). The ARMS and KAC FFHG's are naturals. While linear dimensions remain equal, I've scaled down the diameters of my gas piston to make the attending assembly more kompakt (and lighter). That's why the revised piston appears to be longer. Everyone that comes over has been subjected to a "You gotta come outside and SEE this" pitch. The action of the system seems buffered with my new parts, and ejection pattern is more predictable and more closely grouped rather the the erratic ejection pattern sometimes exhibited with the direct gas impingement system that dates back 60+ years. It's time for more substance than flash on our system. I'm pleased. More later, I have to work on all the 'other' stuff that's piling up here. Thx.

[RJ Shooter]

So, tried it in FA yet????????

[KurtsKustom]

That's next, maybe today. I have to transfer the carrier key to one of my spare carriers. Thx.

[KurtsKustom]

SF ROCKS! It's a beautiful day in Central Florida! Thx.

I don't know WHAT it looks like under the HG http://www.kurtskustomfirearms.citymax.com/i/Misc/HKm4upper.jpg, but I'll bet your old bud's is NOT far off. This looks WAY too familar. I'm going to try M4 HG's. I'm going to go see if they have any more info on it. Thx!

[KurtsKustom]

"Unique Features:

Gosh, I'm completely flabbergasted!

Gee, this is a world-wide joint venture (read the hype in the links above), and a dickhead like me can come up with an UNRELATED KKF M9Evo system in a little hole in the Florida Swamp...

[recon]

Okay HK has there proto there and you have the hook up? So this means?

[KurtsKustom]

No, I did say that wrong. What I mean is this system is here today, at the Swamp. Go to the first post. Totally unrelated parallel developments. This system has its base in the M17S, for which I so admire. I feel my system has merit, but with HK throwing their hat into the ring, it make for an interesting mix.

[recon]

I'll say! This will be interesting!

[KurtsKustom]

Another way to put it is that I've scooped HK. My next new product is aimed directly at them. Thx.

[recon]

Really?

[KurtsKustom]

Why yes! A new buzzgun!

[recon]

Care to be more specific?

[KurtsKustom]

It's 45 ACP, and based on the M16 system. Preliminary examples will be Military/LE units. OTT, I cannot be too much more specific as a patent is involved. Thx.

I think Kurt's FSB is more streamlined than theirs BTW. Interesting though that they are using the H&K Diopter sighting system...

[KurtsKustom]

Yes, that's a NM carbine FFHG, another option that provides a heat shield. Got mail! THANKS! Check yours. Their gas block covers the bases for accessory mounts since the HG is not railed. Notice how the tapered pin attachment intercepts the P-rail. If I did something like this, they'd have a field day w/me. As far as the sight, what did you expect, an M&A part? THX!

[recon]

Actually I was talking about the gas tube! Looks to be heavy duty looking!:D So that machine does what? Listen when this all comes together I hope you give us a first chance to get one of these.

[KurtsKustom]

THAT machine can do so much for me, including my latest endeavors on improved gas systems. THAT machine (NC lathe) makes me stiffen (wood) like a vintage MC, so you can see where my heart is. What a great addition this would /will make to the new shop, and I'm working on getting this piece right now! M9Evo systems will be available 4/04 if all goes well. There seems to be quite a bit of interest. Titanium for testing should arrive next week. BTW, uppers with fixed muzzle attachments will utilize my new 2-piece gas block. Look for it very soon (waiting on material). Thx.

[recon]

I don't suppose you have a price for this system yet? Like just the new tube or complete rifle? :D

[KurtsKustom]

Systems will start @$150 ON YOUR UPPER. Thx.

So what are we looking at in those pictures? Also I would like to know when I could send you my upper to put this on my Bushey? :D

[KurtsKustom]

A combination oprod guide and spring seat. With a FFHG nut, you have a guide and spring seat built in. Not so when using a standard barrel nut/HG setup. This piece of SS provides both. This took me some sleepless nights to figure, and lots of doodling. This system also has the titanium oprod. This barrel and system goes to Leitner-Wise for eval. Thx!.

[KurtsKustom]

RJ, check your e-mail. More details. In a word, I'm stoked. I'm in the running!!!

[RJ Shooter]

I hope to be one of your first "conversion" customers!!! ;)

[argwarrior]

I've been trying to figure out what to get if the ban sunsets, and I think this just went to the top of my list.

I read about some problems with carrier key breakage in some of the op-rod conversions that were made in the past, and that HK had reinforced theirs to fix that problem. This was the last remaining question I had about the KKF system, aside from "you want a credit card or a money order?" :D

It is nice to see enterprising US businessmen working on stuff like this. Even if HK does offer their uppers to the public, I won't shell out the cost of an entire AR just to get one of the few products they they bother to offer us, when I can get it instead from a US company that doesn't let politcal correctness influence their sales decisions.

[recon]

First customer? Now wait a minute! ;)

[nf9648]

I think youve sold another one to me in the near future, you said starting at $150 for the complete upper? What kind of options can I add on to that price?

[RJ Shooter]

I'd guess it's the cost of retrofitting YOUR upper, not a complete upper! ;)

[nf9648]

Damn, $150 for a complete upper was a steal, I suppose I can still send in a upper for that price, it sure beats digging off carbon with dental tools. I may as well just buy the parts and send them to him to assemble the upper.

[KurtsKustom]

The complete conversion on your upper will be around @$300, with the steel P rail gas block installed. Thx!

[recon]

Confused! $150-$300? If I send you my pre ban Bushey upper it will cost me? :(

[Epinephrine]

Got a couple question:

1. Do you make one for 20" barrels?

2. Do they have to be govt. profile to work?

3. Will you gas system fit under a Knights RAS?

4. Can you modify the stock front sight or must I use you folding sight?

5. What all do we need to send to you besides the upper? Bolt carrier?

6. How much?

Thanks :up:

[KurtsKustom]

1. Working on it now.

2. No.

3. It works under M4 HG's with the upper shield removed.

4. No.

5. The bolt carrier must be modified to accept the new key.

6. @$300 with steel P-rail gas block (that's a CYA price).

Thx!

[recon]

Update?:D

[Epinephrine]

I think he fell off the end of the earth again.... :lol:

I want my gas system damnit! :D

[KurtsKustom]

Nope! But if you were me, you would get it. There's one hell of a lot going on here other than the Evo. I wish I could just prototype and R&D, but there's bread labor to do. That's the best part about putting together a crew. It gives you time. The final key will be coming out of heat treat soon.

[RJ Shooter]

Sorry Bud. :(

[KurtsKustom]

Sorry? Don't be sorry! I'm doing better than ever concerning the focus of the business. My bud in the industry has been saying this for years, "Focus on what you do. You don't need the rest of it. You've done well in honing your business into what it will become." It's tough when you're such a stickler for exactness, so tough you can only trust yourself. I'm hanging in there, searching for that piece of crust I deserve. Leaving those feelings that I was raised with, that of not being deserving, was the toughest part. I give/gave my children POSITIVE reinforcement!

I haven't been able to get in here for a long time! Don't know why. A while back, this place was REALLY effed up with spam. YES! I'll be offering the M9Evo up VERY soon. Fact is, I lost my finisher, wooed by the promise of easy money by my brother-in-law who manages a machine shop/manufacturing facility in Leesburg. So, it's back to it all falling on me. I'll get him back (my #4 son), and he'll be even more ready for a position here at KKF. He's operating a CNC over in Leesburg, so he'll be well prepped to run my CNC's when I get him back. Then we can really spit out Evo's! Thx.
