(In case this isn't obvious, I'm claiming credit for two things: the formatting and any errors. Uber provided the text and pictures. He's not claiming to have thought this up, either. I just couldn't find a writeup for this, so I'm trying to save the next person stuck with an SSPB some work.
<taerKitty> I read about people plugging the release valve on them, but I can't find a writeup on how to do that. The two SSPB writeups in the mod directory are not helpful in that regard.
<Uber> First, remove the stock barrel and AR, as per the writeups on the haven.
<Uber> Use a hacksaw or other cutting thingy to cut the end of the lower pump tube off. cut around, not through, or you will cut through the pump itself.
<Uber> Then, remove the pump, which will be easy to take out now, and plug the oprv with hot glue or whatever.
<taerKitty> The flared piece? Where's the OPRV, though?
<Uber> Yes. It will remain on the pump, don't worry about that. I actually cut about 1 cm in, not the entire piece.
<Uber> On the end of the pump itself, as most oprvs are.
<Uber> OK, after that, glue the piece of the pump tube that you cut off back onto the main tube, with the pump attached, then wrap etape around it.
<Uber> I just realized I had pics of the mod process on my photobucket!

<Uber> That last one's the OPRV.
<Uber> Here's the cut I made.

<taerKitty> Is there a writeup on this on the Haven? I can't find it in the search.
<Uber> No. I thought of making a writeup at one point, but it's not worth it. I have all of the pics on my photobucket though.
<taerKitty> Can I post this, crediting you?
<Uber> Absolutely, do whatever you want Feel free to use my pics too, if you wish.
