Weird PP700 stuff

[YEMX]

I have NOT forgotten about this build- but I definitely put it on the back burner, as I need more than a few custom parts for it.  I've made one change, and sat down and did some more measuring...

I'm still converting this PP700 to .20.  But I've decided to build it as a dedicated carbine.  Though the stock will be more akin to a bullpup stock.  I'm taking some inspiration from the Lelya.  Should be a nice, compact little gun.  The Lelya is 23.5" OAL w/o an additional moderator.  I'll try to stick to that OAL (w/no moderator), but seeing as how the the pistol is already 13.125" OAL already w/the LDC adapter, I'm not sure how comfortable a 10"+ stock is going to be, but we'll see. 

I'm going to re-purpose a AF barrel.  I'll have to create a "filler piece", to take up the breech section of the AF barrel, as the straight section of the barrel isn't long enough.  It's fine, since the O.D. of the barrel needs to be reduced slightly anyway.  I noticed a lot of play when I inserted the factory PP700 barrel, so I'm going to simply match the O.D. of the barrel to the bore of the receiver.  That way, there's no more play.  Other than that, I'm going to copy a factory barrel.  This way, I can re-use my barrel shroud and LDC adapter.

I played with the idea of using a .22L CF tank, but the metal tanks are cheaper and shorter than the CF tanks.  There's a weight penalty, but it's fine.  I can finally use my Dr. Bob tank mounted bipod mount! 

The .22 breech block I have (has feed tabs) will be too big for .20, but I suspect it'll be just fine.
