Long story short... Got divorced and had to part out my rifles. I kept the lowers and parts kits minus FCG's.

Started to order new parts lastnight. Here is my list so far.

Lower:
Aero gen 2 lower
DD parts kit
Larue MBT-2S
Magpul CTR
BCM Extension
Tatical Springs white
Spikes ST-T2
BCM mod 1 grip


Upper:
Aero stripped upper
BA 10.3 Hanson performance series
Sharps DLC BCG


I still need to decide on a CH, Rail, and Comp.

For the rail i'm pretty set on the BCM KMR, the other two IDK yet.

Please feel free to toss your comments out. Its been awhile and the amount of new parts out is shocking.

Hopefully stuff is changing, because I've been wanting a BCM KMR for a long time, but have never been able to find one.  

I'm partial to SLR hanguards now.  There are a lot of options currently.  I'm either going with Geisselle or Midwest Industries on my next upper.

Also, be sure to check out your Aero stuff closely.  I've been reading a lot of comments about problems with their machining.  I've not had a problem with any of my Aero components, but apparently boo-boos are out there.  

You've probably also noticed that there are a lot of affordable muzzle devices now.  Take a look at the tests from The Truth About Guns.  They have a few videos on YouTube and data sheets on their website.  Should help guide you to what you want.  I have the cheapies, like the J-comp and the JM.  And expensive stuff like the Lantac Dragon.  They all work good enough.  I don't know if I'll be buying the more expensive stuff anymore.

I bought a Raptor CH from Red Barn Armory a few weeks ago for $65. Looks like they are out of them,  but Joe Bob's has them for $75.

These and the BCM charging handles are an awesome upgrade from the regular stock charging handles!

Ended up getting a 9" kmr, vg6 epsilon, and raptor CH. Thanks for the input guys.
