Just bought a M70 Win. Stainless Classic in .375 H&H AI. It has a muzzle Brake and I need to know if the threads should be greased, left dry or use an anti-seisure grease.

Thanx in advance----Hip

I usually use a very small amount of anti-seize or lithium grease. That said, I've removed many brakes and have never found one that had an issue because of dry threads.

Remove muzzle brake.
Install thread protector.
Discard brake.
Maintenance complete.

I was about to say most general muzzle brake maintenance can be taken care of with a hack saw, flat file and a crowning tool.

I've got a coupla Vias stainless steel muzzle brakes, .25 cal and .30 cal.; they came with a small steel rod to help tweak them on/off.

They do accumulate alot of discharge in the ports - I put them in the dishwasher when Mrs. Gerry isn't looking then scrub the ports with the apppropriate caliber cleaning brush.

I usually dab (little) lube on the threads, too but then again I muscle them on with the rod(s) pretty snug to ensure they don't work loose.

I've been shooting muzzle braked rifles since 1992. All I have ever done is remove the brake from the barrel, wipe the interior and threads of the brake with a rag or patch wet with solvent. Wipe it dry and apply a coat of oil with a rag or patch wet with oil. I wipe off the exterior barrel threads with solvent, then dry and oil as well. I haven't had them seize or work loose on any of the five rifles I've had with muzzle brakes. I remove them each time I clean the rifles.

Lately, when using Wipeout, I place the muzzle brake in a ziplock sandwich bag and slide the bag over the muzzle of the rifle. When I apply the Wipeout through the cleaning rod bore guide, the extra foam goes out the barrel, into the sandwich bag and coats the muzzle brake. Then, I just wipe the brake out and wipe down the barrel threads with an oil impregnated rag. That's been workin okay so far.

Thanx for the replies guys !

I tell my customers that the brakes that I make are self cleaning. Just fire a couple of shots through it and it will blow out all of the excessive carbon. I make them, I can say whatever I want. I have never seen one carbon up to the point where it would affect the way they work. So, I must be one hell of an engineer and I have never heard another outfit make a claim like that. It would probably be even better if I could say it with a straight face. But I'm sort of funny that way.

If you can't dazzle them with brilliance, baffle them with bullshit!

I like what you did there.

I know what you mean Speerchucker. In my all of 72 years I was only wrong once------I THOUGHT I WAS WRONG BUT I WASN'T!
