I was happily playing around with my Big Bad Bow, when I heard something break as I shot. Then, I couldn't cock the gun and it was acting goofy. I took it apart, and realized the little disc the is under the plunger head had snapped!

I wanted to reinforce this disc, but I also needed to keep it removable to be able to switch the spring. I decided to use a metal washer like TriggerHappyAzn in his thread. This is the washer compared to the disc.

I decided to cut the metal washer to fit over the disc, yet not conflict with it's removal. I set up the disc to be cut to align with the slit in the disc.

I put two metal washers on in this way, one on each side. I used super glue to attach the washers.

It fits on like this.

I've put about 100 rounds through the BBB since this modification, and everything has held up great. The washers have stayed attached with the super glue and the disc has not snapped.
The washers cost about $.09 each. So this, in my opinion, is a great reinforcement that is incredibly cheap.
