I just got a used CompM and am VERY dissapointed in the battery life (and brightness) using the 1/2 N lithium battery.

Has anyone made a battery extension that would allow a either a cr2, 2-N cells or 2-AAA cells to be used.

It seems like a 2-N extension would be very easy.  

2-AAA's could use a side by side configuration with a slip ring for screwing down.

Otherwise what are the options for either making the dot brighter or extending the battery life?


Thanks,

How about this battery extender module?

I'm using a CompM and have the same problem.  The brightness seems fine, even in the Iraqi summer but my battery life sucks.

If someone could give me the thread and pitch I might be able to make something up.  I would have to buy the taps and dies for threading and maybe a small copper tube.

I never had any problems with my Comp M.  But I don't leave it on all the time, even while at the range.  Only complaint I have is the dot is too large.

Too big, isn the comp MXD a 3MOA dot?  

what are you guys getting for battery life?

On my box it says 10 MOA.  I have an old one, not sure exactly what MOA the dot is.

I get about 15 hours.  I leave it off most of the time but I always seem to bump the knob with my leg or turn it on by accident when my rifle is slung.  I guess I might break down and buy a newer Aimpoint when I get home.

Hmmm, My used USGI CompM- although not as bright as compared to my ML2,
is still rated at 1000 hr. Battery life(setting not specified) vs. the 10,000 hr. CET of the ML2/M2 models.

Piehole-The Aimpoint battery extender does nothing to extend the battery life nor
increase the dot's brightness. It simply holds a spare battery. Now there was an aftermarket
double batt. module that does what wwglen is looking for, but appearently it caused overloads and fried
the circuitry in Aimpoints(Guess that's why ya' don't see 'em too often).

Inferno-Are you sure your's is not an Aimpoint Comp(Not M)? Aimpoint Comps are identical to the Comp M/XDs
except that they were intended for pistols(race guns) hence the 10 MOA dot.

Best bet would be to step up to the ML2/M2 for better battery life and performance or go for the gusto
and pick up an ML3 or M3.

It says 'CompM' right on it.

Aw shit.  I thought I had just gotten a smokin deal of the EE for a comp M or what I thought was the XD model.  It has the flip ups and the wire retainers on it so I assumed the XD which I thought was the older one with the 4moa or 3moa dot.   gonna be pissed if it shows up as the 10moa thing.  DAMNIT!!!!!!   I hate waiting!

Don't take too much stock in what I wrote.  I have no idea what MOA dot I have.  I know the other Aimpoints I've looked through have had smaller dots.  I'm not even sure the box I have is the original.  I got it used at a gunshow.  It works great so I havn't upgraded to a different model.

I just put a new USGI battery fresh out of the wrapper in my CompM.  I turned it on to the middle setting.  It's 7pm, I'll see how long it can last.
