Right now I'm looking for storage solutions on my stock. I currently have a Magpul ACS which theoretically has storage... Except, I can't fit the batteries I need to (18650s) anywhere on it. Not in the trap door nor the battery tubes. I'd like to find out which adjustable stocks have the most storage space while not being some off brand garbage. The troy battle ax looks like it'd have all the storage I could ever need, and if that's the best option, I'll go for it... But man that thing is a serious uggo. The other one that looks like it might work is the BCM gunfighter mod 1 with the storage compartment, but I'm not sure if the compartment will fit 18650s.
On my rifle I'm looking to store 2 18650s, 2 cr123s, a couple cr1632s, a small bottle of lube, and if I can fit it, an extra bolt+firing pin. I'm thinking bolt and firing pin in the grip, however I'm not opposed to moving those to the stock, except I can't fit 2 18650s in my grip so it wouldn't really solve my problem.
Thanks y'all.
