Surefire C3 w/Malkoff M60 ......rattles

[Robertesq1]

I noticed that my Surefire C3 w/Malkoff M60 ......rattles when you shake it (not a great scenario for my "tactical" light), I think its the batteries, did not notice it b/f... Checked it out and it looks like there is some headspace now (the head does not screw flush). Anyone having the same issues?

Need more info. What batteries are you using? The M60 is secured by the bezel to body tube connection.
The batteries do not hold the M60 in place. If the M60 is moving, then there is definately a problem and this will lead to poor heat sinking.

I am using surefire batteries and I think it's the batteries that are rattling, not the bezal...

You could get a sheet of paper, write contact info on it and wrap it around the batteries. That way, it fills the empty space around the cells and in case you lose it, there's a note inside to let them know who it belongs to. :twothumbs

My Malkoff 6P's rattle a little when shaken. But you have to really shake them like you do when your jogging.

I find if I twist the light 180 degrees, the rattle stops. It's only very minor so I normally don't bother. Maybe the C3 has a larger bore than the 6P's.

The rolled up paper trick would work.

I taped up my 18650's for my Leef U2 body. My U2 rattles when tapped on my palm with CR123's in the SF body.

I have M60's in my C2, 6P & G2 with no rattles.

You are having headspace with your C3? Just checked my C2 and no headspace. Are you inserting M60, then screwing head down before you add the batteries?

Bill

Just got thinking. The spring on the M60 is shorter than the SF LA springs so you may need to add a spacer to batteries to make better contact (no rattling).

The Bezel doesn't screw to the body flush... There is a very minor gap 1/32 inch maybe, I though tat this might be the cause for the rattle (and don't get me wrong you have to shake the light to hear it). I will try the paper trick unless someone has a better idea. Thanks to all.

the gap is normal and means that the module has been properly seated. With no outer spring a direct connection must be made, Almost all 3r part LED modules work in this way for the D26 sizes.

So did you try shaking the light without the batteries in?
Seems like this would be the best way to ascertain if it is indeed the Malkoff.

Good Idea! Sometimes I am actually slower than I look will do so....

I just tried this with my HA C3 w/M60 and BatteryStation batteries. With the batteries removed and the tailcap tightened so that the lanyard ring doesn't rattle, I had no rattle when shaking the light. With the batteries in and the tailcap tightened, vigorous shaking did produce a slight rattle. I wouldn't have thought this was enough to be an issue since I wouldn't expect this kind of shaking in a tactical situation, but I don't have any tactical experience. Moving the light around smoothly did not produce a rattle.

You are probably right... However as a retired LEO, old habits die hard..... a noisy flashlight, squeaky shoe or jingling sling tends to get the focus of my attention.

In general the bezels will not screw down fully - there are threads here on why - but it has nothing to do with rattle. I'll bet you a beer that it is the batteries being smaller in diameter than the tube ID. Some of my SFs rattle, others don't. Some rechargeable cells have greater OD than primaries and some users consider that an advantage. Check with the P60 LA and see if I'm right? If that's the case, paper makes an excellent, nonconductive, spacer.

Bingo! Problem: battery rattle... Solved with paper spacer. Thanks hive mind.

And I don't blame you - those habits helped keep you alive. Now that you have brought this to my attention, I may try some paper to quiet things down.

Is that your noisy flashlight, or the perps? :huh::nana:

I just hated going up a dark stairwell and having a partner that sounded like a noisey wind chime....

Put a spacer in between one of the batteries. Batteries are rattling because they are not making firm contact top and bottom.
