I like stainless as a material. Easy to clean, etc. As you mentioned, not any more expensive in this case.
I chose the gas block wrong... I should chose rifle length.
I didn't catch that the MOE handguard doesn't free-float. Thank you.
It looks like to do free floating rifle length - I'm looking at $125 or more... That takes me to above the cost of buying it as an assembly from BCG.

If I build it as above, am I coming out ahead in terms of better components and accuracy? I read that BCG's stuff has a great reputation.
A mid-length gas system isn't horrible. It will be less "gassy" than a carbine. A rifle length system would be better yet, but if you've already paid for the mid-length, don't worry about it. It's not THAT big of a deal.

As I mentioned before, the barrel is the heart, the backbone. It's the single most important piece for accuracy. With the MOE hand guards, accuracy will not be horrible, but it would definitely be better with a free-floated system. The good news is that hand guards are easy to swap out. You can go shoot the rifle for a while, get used to it, maximize what you can do with it, and then float the barrel later.......if you even feel the need to. If you're happy with the results, why change? My wife's carbine, which my son and I built for her, has MOE furniture, with a 16" ER Shaw M4 profile barrel with a 1:9 twist and a carbine length gas system. It works just fine, and is as accurate as she needs it to be, out to about 100 yards. She's never shot it beyond that distance, but at that range, using an EOTech and a 3X magnifier, it is about a 2 MOA gun.......which is right about what you'd expect for an M4gery.

Speaking of that EOTech, have you given much thought to iron sights and some kind of optic?

I haven't paid yet.. You're helping me get it sorted out before I make a mistake!
Based on above - building it costs me more than buying it assembled from BCM... So I'm leaning that way, unless I understand that what I'm building is superior.

I'm leaning toward optics, not iron sights. If I was trying to get this thing to hit something at 200 yards, I think I'm looking at optics in the 4-8x max magnification range. Preferably adjustable... Those are my current thoughts. I've done a few searches and Vortex comes up quite a bit...

I got one of BCM's uppers with the KMR handguard recently. I have to say it is very cool and you can attach rails without removing it.

I am glad you didn't list the Magpul MOE buttstock. They seem too flimsy to me.

I've seen complete rifles less than $1300 but you will have to pay tax, shipping, and ffl fee unless your in N Texas. IIRC I've seen just the upper for less than $800 or hell go for DPMS 3G1 rifle. They go for $1100

I wanted finalize this. I went over budget. Total budget was about $1400
Basic specs:
BCM SS410 18" Rifle Length Upper Receiver Group, stainless barrel, floating handguard, 1/8 twist = $800
Hayes custom guns lower and parts kit $175
Nikon P-223, mount, bipod $240
MAGPUL PRS + Giselle 2-stage trigger $370
P-mags (5) $50

= $1395

Link: http://tinyurl.com/kvtts3e" onclick="window.open(this.href);return false;

I appreciate everyone that helped.. Great recommendations here! Largely I bought that assembled upper as I couldn't "build it" for much less myself.

That's very similar to my own, except for the stock (and my $900 Viper PST scope). I have that stock on a SASS rifle in .308 I own. It is a good stock, but the PRS is heavy. My DMR has a VLTOR EMOD stock. We have very similar handguards (mine is a Samson 15"). We have the same barrel length, gas system, and twist rate. Is yours Wylde chambered? The BCM page didn't say, but Wylde chambering seems to be real common with 1:8 twist barrels.

I think you're going to find yourself really enjoying that rig. That's a good intro into the AR world. Have fun.

Apparently BCM uses a SAM-R chamber. I wanted to shoot both 5.56 and .223, I don't "think" you can do that with the accuracy of the Wylde chamber.
I got it "on paper" this weekend - probably get to mess with it at a real rifle range this weekend.

Again, I appreciate all the advice on this forum.

Wylde chambers allow you to shoot both calibers with accuracy. Obviously ammo quality matters and you'll get better results with match/OTM than with bulk milsurp, but you can shoot both safely.
