I’ve got a POF gen 3 set up with a mil- spec trigger, KNS anti/ walk pins, Nor-Gon ambi mag relase, and a Magpul B.A.D. and MIAD. I ordered most of my parts thru Brownell’s here in IA.
If you’ve got the cake I suppose you could go w/ a Colt LPK. I think they’re about $200 though…
For pins you could go with KNS and for the ambi selector, I think you’re fine with any reputable maker… It’s a pretty simple piece of metal (LMT and Stag both have one)
The ambi bolt release came with it. It is 4 pieces. No instructions.
Do I need to buy this, too?
Norgon Ambi-Catch
Get quicker, easier reloads for right- or left-hand shooters. Lets you activate the magazine release with the thumb of the non-firing hand while keeping the rifle on target. Distinctive design is the same size and configuration as factory part; won’t snag on clothes or branches, resists accidental release and does not interfere with rifle function. Drop-in installation. http://www.botachtactical.com/noam.html
