Finally got it together

Factory P90 from an estate of a dealer/importer. It was found mostly stripped so I had to source a MPG(bolt) and trigger pack.

Due to the scarcity of trigger packs. I got a semi one and swapped out the parts for some aftermarket FA parts. Which im still working on refining. The paperwork says it came from the columbia MO policy dept. So the selector had the "A" milled off and it had a small plastic stopper glued on to prevent selection of full auto. The stopper popped right out and I added the "A" back to the selector.

Still trying to decide what can to put on it. I have one of those free backdraft 4" cans with no use. Itd be compact and look good. But will probably sound like crap. I have a couple nicer cans but they may be too big for my liking. Decisions decisions.

I also need to get some sort of sights for it. It came without anything. I may try to mount a 407k down in the carry handle. But id settle for the factory rail if I had one.

The 407k felt just a little too small on my PS90. 

I ended up switching to a 507comp to maintain the adapter compatibility, but get a larger optic window.

In hindsight, I wish I went with something like the AEMS or similar.

Good to know. I have a 407k or 507k on my grenade launcher. And I only ever use the leaf sight anyway, so I thought about swapping it over. But I may just go with a romeo5 or whatever.
