Hello, so I installed the Noveske KX5 on my Semi auto 308 and it's similar to a krinkov style brake or muzzle booster and there is a cone shaped funnel inside the muzzle device with a gap between that and the muzzle of the barrel and on the Noveske KX5, there was a light coating of lube on the outside of the cone in the muzzle device and I started firing it (about 100 rounds) without removing all the oil and lube in the inside of the KX5/on the walls of the cone area in the inside of the KX5 and was wondering if shooting it got the oil back in the barrel as apparently, these types of muzzle devices redirect some of the gas back into the barrel. Or perhaps the escaping hot gasses vaporized the lube?

I am just really worried about shooting my gun even with a little bit of oil in the barrel as apparently, you can create pores in the bore and the increased pressure can damage the bore.

has anyone had a noveske KX3 or KX5 on their rifles and shot them without taking the KX3/KX5 apart? Is your rifle still okay?

my main concern is my rifle shooting with some oil in the barrel.

thanks for the help.
 
There is “back pressure”, but not reversed flow.
The small bit of packaging oil on the brake was vaporized by the third or fourth round.

Yes, do not shoot with any barrel obstruction, oil, water, snow, dirt or otherwise.

You paid for bullet proof. Oil it, it will be fine.

Some rifles come ready to go, some are dirty and have machining chips in them. If you’ve used it, and it worked, it must be fine.:thumbup:

Hose it out, dry it off, oil it up, smile. You own a Noveske. You won’t break it by using it.:)

How does the back pressure work exactly on the KX3 or KX5? What happens to the escaping gas and what does the cone shaped, funnel do inside the housing of the muzzle device?

also, it's likely that the oil on the KX5 vaporized before it can go in the barrel you think?
 
The point would likely be moot at this time, yes?:)

The oil that peens the surface of the bore it the type that is willfully put there, heavily for corrosion protection.
Firing without wiping the bore clean will have the bullet wipe the oil in front of the ogive till it builds up to be run over by the bullet and impressed into the bore, because fluids cannot be compressed or are already or whatever.

This is not happening in your case.

Clean it, shoot it, repeat. It will be fine. I personally promise you. I know if I spent that much on a rifle I would be cautious about it too!:D
But it will be fine, clean it all out now and lube it correctly and enjoy it without further worry.:thumbup:
 
The KX Noveske devices and others of the type retard the gases and release them over a longer period, as a suppressor does but alot less. This creates alonger gasport pressure duration and gives a longer gas gas inpingeme to the BCG . This in very few milli seconds more push. I love my Flaming pigs.

Did you take your KX3 apart To clean all the oil of the KX3 before putting it on your AR and shooting it?

how come some people say that the excess gas goes into the barrel with the KX3 on; wouldn't it be so that the extra gas stays in the muzzle device/kx3 while the rest is still coming out the barrel instead?
 
I took it apart , I have one for an AR, one fora.300 Blackout, and one 14mm for an AK 7.62. I bought the last two from John Noveske personally, and the first one came on the Diplomat pistol I bought when I first heard about Noveske. The instructions do mention a small amount of nickel based antisieze applied to the threads BTW . Powder build ups can make muzzle devices difficult to clean ., BTW. .

Yeah it's hard to take apart but I meant you didn't take your KX3s apart to clean the rest of the oil before you shot your rifles? I don't know why I'm just so worried about getting the oil from the cone of my KX5 into my barrel.

If you were going to, you already did. It is already gone. So you didn’t.
If you don’t put any in there, it won’t happen.
If you put oil in the bore, patch it out.
A muzzle device is not the bore.
The KX5 holds pressure not Ejecta. Oil, gases and soot are coming out, not going back into the barrel.
The device simulates a longer barrel for better operation In short gas system rifles, it does not “catch stuff” and blow it back into the firearm.

With each fired shot, the bore will heat to a couple thousand degrees, under several tens of thousands of pounds of pressure. The oil won’t be in the barrel after the first round.
Since we know it won’t be reintroduced through the muzzle brake and that you haven’t put anymore in, you have nothing to worry for.
Take it off when you want to clean if it suits you.:)

What did your barrel break in procedure consist of?
 
Thanks for that find About the KX3. I'm glad I never cleaned my gun yet after installing that KX5.

I don't personally do any break in procedure for my barrel unless it's for precision shooting.

Good. That was kind of a trick question. Had you said yes, I would have asked how you got the solvent out of it, cleaning every shot.
Like in the instructions, that should have also come with your flash can, and alluded to above, any fluid or solvent or oil in it will not compress and will take up the space needed by the gasses under pressure, that may rupture the can with too much pressure. I’m sure it didn’t come from the factory filled with oil, but I would have checked, too.
You now have one hundred rounds through it. It most certainly is dry.

Great find, @243winxb.:thumbup:


Now, let’s see some pics. Gun Porn Time!:D
