Some quick questions...

[Ronin13]

So my brother finally got his Noveske SBR and had ordered a new trigger- Geissele Super Dynamic- and this was, in fact, the 4th time ever in my life I've taken down a lower receiver (never fully taken my POF down, and I'll get to that). Now the question is, does anyone know what kind of trigger comes standard in a Noveske rifle? Bro wants to maybe sell his and we aren't 100% sure what brand/model it is and how much to ask. Now, my other question, and I am curious to know if this is how it is on other rifles, my POF AR doesn't have the usual hammer and trigger pins- instead there's this what looks to be an allen key and a pin block. Is this an allen key (I don't have one that small anyway)? Luckily I already have a Geissele SSA Combat trigger in it, so unless I want to give it a really deep cleaning, I wouldn't need to take the hammer/trigger out.
Here is a pic (don't have the rifle with me at work so I pulled this one off of google):
If you notice just above the trigger is what I'm talking about.

Looks like KNS anti-rotation set up, from the picture of a picture you don't have in front of you.

Okay, looking into it a bit more, it does appear to be allen key to remove it. What's the benefit of an anti-rotation vs non?

keeps the pins from rounding out the hole over time, though that really isn't that much of a problem with the Geissele, but I would highly recommend that setup for anything you were putting a tax stamp on, but otherwise it is a nice to have.

Cool, thanks! So anyone know the deal on the stock trigger that comes with Noveske? I can't find anything concrete. I think it's Stag, but not sure...

Call Noveske. I'm sure they're not busy

Only real benefit is when moving the safety from SEMI- AUTO. Prevents pin "walk"
The allen head set up is one way to get around patent's, copy right, etc. I have some early pins that are expanded head on one side and an e-clip on the other. Same deal, different price point and cool factor.

I did some looking and it depends when it was purchased and what style was installed, single stage or two stage

It appears they have used a variety of triggers in their builds, my guess is this was based on what lpk they could get at the time that met their standards.
