I need your hook up. Where are you getting the SPR upper for that, much less the lower...:munchin

No problem none taken. Is that Jet titanium. If so I wouldnt use it on anything but a bolt gun if I were you.

Why is that? I was part of their reseach and development team for several months before leaving. I never once had any problems with any of their systems. M4 SBRs, full auto suppressed, Suppressed G36, UMP, MP5, Plus several bolt guns but I was most impressed with how well Mike's suppressors worked on full autos without any failures, no explosive backbuild, no warping, and the titanium woked great as a heat sink for the barrel transferring barrel heat to the suppressor which cooled fast. Only thing was when firing through the full auto M4SBR, after 2 full mags firing cyclic, the suppressor would be white hot, we measured it at just over 1400 degrees once. One idiot made the mistake of leaning a hot can against the front fender of his car, lol. Melted right through it and started melting his front tire before he noticed it. Steel belt was exposed and everything lol.

here's a couple of pics from our testing at Jets on this page

Titanium is a very strong, light, hard metal. When heated It is still light and hard , but it doesnt resist erosion well in that state. Or as it is offficialy known as, Oxidatiion. Its fine on a bolt gun. Youll never get a can hot enough to make a bit of difference, or fire it fast enough for that matter. Youve said that you got the cans white hot. Id like to see a picture of the blast baffle of those cans. It probably looks pretty bad. The oxidation of titanium in extreme temperatures was known a long time ago. Its why NASA decided to use Inconel in the shuttle engine parts that would recieve the most heat. Over half of its parts are made of Inconel 718. Grade 1 untreated Titanium is good up to around 600 degrees. Grade 5 is good to 900. Keep in mind that one rapid mag dump will put your can into the 600-800 degrees farenheit range. Thats hardly white hot. Inconel 718 is a heat treated alloy composed of at least 50% nickel. It is rated to handle 1300 degrees F for extended periods of time without significant loss in yield strength, or weight loss due to oxidation. Inconel is what is used in many name brand silencers including KAC, Surefire, AAC, SWR, and Gem-tech just to name a few. Jet is 100 percent Ti and I dont even know what grade. Titanium has been proven it is not a satisfactory high temp metal. If you dont believe me just read the numbers.

The one to pay attention to is Tensile strength, or yield.

Pure Titanium, as it comes out of the ground.

NDD:

We are talking about the KAC M-4 pricing, which was high (around $1300, IIRC), when it first came out.

An SPR is a horse of a different color, though by the time you build an SPR upper with the barrel, receiver, rail system, sights, suppressor adaptor, bolt carrier group, charging handle, gas block, mount and optic, and drop a match trigger and A1 stock into the lower, you are into some serious coin. I had one that an AMU smith built, it wouldn't shoot, so I took it to my long gun 'smith and he built a great one. I got a deal on the scope and some other parts, but I agree, just the SPR upper, minus optics probably has well over a grand in it.

I have shot the SureFire shorty can on a SAW, burning a 200 round ammo pack through it as fast as I could in 6-9 round continuous bursts, as well as putting 15 full mags through an M-4 with the standard FA556 can in less than 5 minutes. In both cases, the suppressors had heated through red to a straw color, but the bullets were still flying to the same POI and there were no problems, before or after. The SureFire suppressor guru said that they had cut down one of their cans after 30,000 rounds and there was no appreciable wear on any of the surfaces and it all miked out to as new specs. IMHO, there are very few cans that will take that kind of abuse and keep running. Some require replacement of internal parts in as little as 1,000 rounds, and you can no longer buy rebuild kits, you have to send it to a licensed manufacturer for rebuild.

On a separate note, the suppressors do blow a lot of gas back through a standard M-16 type weapon with a direct gas impimgement operating system. I always use the Gas Buster charging handle, and it still blows oil and smoke through the receiver all over my shooting glasses in a long range session.

Agree about the Ti. Great metal for the right application, but it will not do everything well and does not like extreme heat.

Knights pricing is still high as hell and their kit is nearly unobtainable. That lower alone could probably be sold for a substantial markup. KAC fans will pay almost anything to get their hands on it. I bought a MK11 full kit SR-25 Navy gun for a very good price. Im sworn to secrecy by Trey but it was a great price. Its a great shooter, But that money looks alot better in the bank. I sold it for nearly 8000 dollars profit. Seriously.

My understanding is that almost all KAC parts sold on the civilian market are rejects or seconds off the government projects.

I got this one from the owners son. I can assure you its all matching and a real Navy gun. Ill post a photo in a few. I just got it out of the safe so I can send it off. In the past I might agree with you. Reed had and still doesnt have any concern for the civilian market. Trey (C Reed Knight III) is trying to change that with Lawmens and so far it seems to be working slowly. The attention is still not paid to the customer that should be though. I got my stuff pretty fast but I know Trey personally. Not everyone is as fortunate.

EDIT I read your post too fast. Yes everything is either rejects or runoff. They dont tool up anything special for the civilian market as far as I know. As long as the US has a contract there will always be a small supply of KAC stuff. That little bit of stuff commands a high price and is probably the reason for its small following.

This is some very interesting information to say the least. Definately has my attention. I'm still able to communicate with the owner or Jet through Email, and better yet, a close friend of mine starting working there as a new machinist, and I know if I forward this to him he'll be straight up with me about the material. That is, if he even knows himself. I remember passing through the machine shop after a range test, OSPEC was priority with them, they didn't want any cams in the shop period, or even our eyes in the general direction of the machines while they were cutting a new batch.
