It's finally together.
I ended up using:
• Wolff reduced power trigger/disconnector springs
• Unknown takeoff mil spec trigger (hammer tail cut-off)
• Unknown Fleabay trigger-less LPK (worked fine though the roll pins were soft as hell) These jokers labeled it CNC machined and parkerized though it's obviously neither. They claim Japanese steel, though it strongly suggests Chinese. Almost went Strike Industries but didn't like the look of the safety selector. In hindsight that or even DPMS would have been much preferred.
• Slipstream Precision 22lr receiver plug
• EMA tactical single point sling
• DIY single point sling adapter (drilled/tapped backplate with a sling swivel and para cord)
It's got a crisp 5lb trigger as-is. Not great, but acceptable.
I'll be taking it to the shop to get a pic with the suppressor on it. It looks awkward without it.
I may get an A2 flash hider and 4" FF tube for use without the suppressor. That shortness without a hand stop is a little concerning, but we'll see.
Still waiting on KNS pins, just 'cause.
It's pretty cool. I regretted purchasing that big stupid grip initially, but it does make the gun once together.
The UTG red dot is a bit of a dissapointment, as can be expected. The settings don't have much of a range, light transmission sucks, and it's not particularly bright. Looks like green works best outdoors and red will be fine indoors. It was donated to the cause so I can't complain.
I wish I would have aquired the short handguard/A2 FH in anticipation, but there's always next week.
