Don't be surprised if this piston housing also blows to bits. You could have got bubbles between the glued joints from when you pressurized it. Then again, the joint may be fine. Who knows.
Would I use it personally, no.
I realise this post will do little to change your mind but hopefully you'll refrain from ignoring instructions in the future. You're supposed to wait 24 hours for a reason.
Thanks for the warning, but its fine! I have been using it for 2 days now, and about 80 shots!! Next time, I will wait though! I also added the extra washer to the front. I just got 300 balls from the range earlier tonight so this thing will be doing work tomorrow!!
