This was my first AR15 build, I have a DD MK 18 that was my first rifle purchase but I bought it as a complete rifle and just added accessories.
I just completed the build about 2 weeks ago when I received the upper/lower and rail, and today was the first day since I signed up at my range that we were able to shoot .223/5.56
Here is a list of the parts and a picture before I started assembling it
Noveske 7.5" barrel
Wilson Combat billet upper/lower set
Spikes Tactical 7" Bar2 rail
Geissele S3G trigger
Troy PDW stock kit
Troy vertical grip
Aimpoint T2
Fortis Aimpoint mount
Raptor charging handle
BCM Mod 3 grip
Ferfrans CRD
Norgon ambi mag release
BAD titanium pins
BAD safety selector
And here is the finished product
This is the best clip I got with my camera phone, its not me but a range officer at the range. Trigger is amazing so rapid fire is super fun with this thing, and we sure drew everyones attention at the range with the blasts

I couldn't be happier with how it turned out, and its performance. I ran about 400 rounds though it today and it ran great on 5.56, when shooting .223 I got 3-4 2 rounds bursts and 2 3 rounds bursts. After that happened I switched to only 5.56 and had no problems. I think the built in buffer weight on the Troy BCG works better with the 5.56 and may be too heavy for the .223
