If anyone is interested, I have devised a waterproof storage solution to carry spare 2032 or similar wafer type batteries in the buttstock. It requires the purchase of the Magpul AA/AAA grip storage core and the use of a Dremel, coarse and fine files or a bench sander. Some close-cell foam would be handy as well to keep batt rattle to a minimum.

There's a pocket in the buttstock once the recoil pad assembly is removed, it can hold two (2) 123a or CR2 batteries but not in a waterproof compartment. You have three (3) options, after modifying the storage core you can leave it loose, or using epoxy adhere it to either the recoil pad backing plate or in the buttstock itself. I will post photos later today explaining in detail how it's accomplished.

If you're like me your SCAR has battery needs, my scope is illuminated requiring a 2032 batt and my tac light requires a 123a batt. I have already swapped the AA/AAA storage core for the 123a version which left me with a soon to be modified core. Once complete I will be able to carry two (2) spares of each type battery.

Nice idea it seems like your never sitting still and always thinking about ways to improve this platform. Hmm! maybe fn is hiring for new ideas and innovations for the scar.

The nice thing, it doesn't need much in the way of improvements just some minor tweaking's taking advantage of what's already there.

So, most people are going to need a 2032 battery for an Aimpoint Micro or possibly a MRDS. If the former, Two thinks come to mind: (1) the battery life is long enough that an on board solution is not really required but if one does want one then (2) KAC makes a replacement battery cover that is waterproof, stores an extra battery, and has some tactile improvements. Sure, it's $30 versus a cheaper Magpul grip core part, but it's plug-and-play and requires no fitting, etc., not to mention the value of my time (which is obviously quite low today since I'm posting in this thread hahaha).

That said, more power to you if you like to tinker and want to roll your own. I couldn't imagine a huge market for what is being described here, unless it's just an info-sharing venture.

Right on the head KW, just an info share, not concerned about any market, not everyone has "dots" mounted and I can't imagine a scopes illumination lasting for years if left on, nor is leaving one on recommended. I and perhaps others are already using their grip storage for other items, in my case two 123a's for my tac light. Why let a perfectly good storage space go to waist when $15 will fill it nicely and secure it from water?

Yes.....I know and here they are. From start to finish, how to make a waterproof wafer/button type battery storage compartment in the buttstock of a SCAR!

What we're after, trying to utilize the circled space as the pocket for our batt storage compartment.

Much nicer storage option than my store brand sandwich bags. I don't even spring for Ziploc.

If anyone in eSOC would like one done, let me know we'll see what can be arranged. I think I'm going to epoxy mine to the recoil pad backing plate that way there's no chance of it falling out and getting lost in the flora while conducting myself like an Operator, operating in python/hog elimination operations. Very tricky these operations, very tricky... :evil:

That's a good idea Kal but it only applies to those sporting red dot sights, my solution is a little more convenient and more permanent. Good idea though, thanks for sharing.

Since we're sharing ideas on battery storage, this video explains a simple and effective solution:
