Parts from tail to tip:
Magpul CTR stock:
Spike's Lower with LPK:
Geisselle G2S trigger:

Oh, and it shoots sub-MOA.....

Nice. I bet it feels great being so light.
it's a mid-length gas system, so it's very mild. I have half a mind to put a comp on there, just to see what it feels like then.
Gentlemen, my apologies. I left off the purpose for this build.
I had two real reasons to build my own rifle, and thusly what I wanted it to do.
First, I wanted to build one. I have shot them enough to get a fairly good feel of the operation, buit to REALLY understand it, I felt that I needed to build one to understand where the stresses are and to find out what was important and what wasn't. I've succeeded in that by getting frustrated at trying to do it without help. I'm glad that. There are some pretty knowledgeable folks here in my area that wee willing to help me out when I said things like, "hey, I think I screwed this up".
Secondly, I wanted to get a semi-precision build on a bit of a budget. I used a lot of take-off parts from that other folks had laying around, and I was able to get things for not a lot of money. I like the fact that it shoots a pretty good little grouping.
Again, sorry for not including it earlier.

That carbon fiber hand guard looks pretty sweet. What's the twist rate on that barrel?

Acetone will take the paint off pretty easily (unless it's an epoxy type - like cerakote). Just be careful around plastic like on the scope, as it'll eat it too.
It's a 1/8 twist barrel with a .223 Wilde chamber
Laid down and shot a group today. After reading a bit, a ten-shot group is the most indicative of what the rifle is actually doing.
Because I use a Mac, I can't use the .exe fancy grouping program. Anyone care to help?
This is at 201 yards (LRF I used was in yards). For reference, the brown colored box is exactly 3 inches wide.

Ammo was Black Hills 77gr hpbt match.
Geissele triggers come with pins for a reason. I suggest using them and ditching the KNS.
What's the reason against using the Geisselle pins, again?
I know they come with them, but why use them vice the KNS?

Borrowed this from the ADCO website for convenience's sake:
"Here is the deal on non-rotating pins
Geissele SSA pins are 0.1550" dia 0.0001. Holes in the trigger can be 5 tenths over Geissele pin size. Kns pins are either .154 or .1555. So they are either too loose or just about a metal to metal fit in Geissele triggers
Geissele pins are chrome-moly steel that is rough turned, rough ground, heat treated and then centerless finish ground. They are a quality pin.
Why do we not recommend KNS pins? One is that they are the wrong size. Can the smaller diameter pins work? Yes, but they are not the intended size and there can be a 'softer" break to the 2nd stage with them.
But the biggest reason is that the KNS pins are soft. Sometimes when they are installed they pull up a burr that causes havoc with trigger operation. I get calls from frustrated customers where they are totally disappointed in their SSA because it either feels terrible or it hangs up. I spend all kinds of time on the phone wracking my brain trying to figure out what is going on and trying to work the customer through the problem. Finally, I ask the customer to send the trigger in (which I hate to inconvenience the customer with) and the issue is that the KNS pins are jamming the trigger up.
A hammer or trigger pin that rotates maybe 1/8 of a turn with each shot, *might* wear through the hard anodizing after a million rounds.
Let it rotate, it doesn't matter, its nothing to worry about. More FCG holes are damaged by people swapping the pins out every other week in an attempt to fix something that isnt broke, to get them to stop rotating.

I'm trying to read between the lines here...
so the real "tell" is whether or not the trigger has a hang-up, hiccup, or other version of something not going right. How much does that REALLY affect things?
I mean the .155" that I have in mine (I went and looked at what I was given) against the .155" trigger means that the trigger, after a while, will wear a spot in the pins because the pins are softer than the trigger?
If this is coming across as me being a jerk, it's not my intent, I simply don't have enough knowledge of this part of the rifle.

Speaking practically, you may never notice a single problem with the KNS pins or even notice an improvement in feel with the Geissele pins. But that doesn't change the fact that they're of higher quality material and workmanship, and may potentially improve the feel of your trigger. It also doesn't change the fact that KNS pins are a solution looking for a problem.
Given that they're free and come with the trigger, it seems like an easy choice to just go ahead and use the Geissele pins / switch back to them. If you no longer have the pins, I would shoot Geissele an email and I bet they'll ship some out to you straight away.
I still have the Geissele factory pins around here somewhere. Seeing as the lower is already built, the trigger doesn't bind or hang up, and the gun shoots pretty straight... I think I'll keep the KNS in there now.
A solution in search of a problem... I can certainly see how that can be the train of thought, and a valid one.
I guess I didn't understand that the pins were something to get that excited about. I got them for free, so I guess I don't really have too much to say about it.
I appreciate the time you took to answer my questions, a0cake.
