Hey folk, Just wondering if anyone has any experience or knowledge when it comes to PDW stocks and what kind of battery sizes work best. I've read in some places that some of these stocks will only accept special types of batteries designed for the stock. Checked PB and they just say 'Stick battery' but the lengths worry me. I fancy a new AEG for cqb and was considering the Spec Arms SA-E10 as it's in the perfect price to performance ratio for my needs. Thoughts?
