I also had a question for you guys. do you put holes in the end of the slug? And is half inch diameter foam backer rod right?

I don't have all the kinks worked out in the system but I know the bladder holds air at least. It increased the capacity of the RM by several magnitudes. Without setting the OPV off it nommed multiple 40rd clips.

I think a small external air tank would work for you. You might still have to pump during a game but you can go much longer without. This would allow a more maintenance pumping/pumping at your leisure.

This is the tubing I purchased for the homemade bladder.
You'll obviously need 3/4'' barbed fittings and clamps for this tube. I got mine from my local hardwood store.

For the smaller barbed fittings (3/16'' and smaller) my store was very lacking so I purchased what I needed from this seller.

I don't plan on using it for big wars.
