New to AR15.....picked up my M&P 15OR a couple of weeks ago. Been to the range a few times and fired off a few hundred rounds, love it. No issues at all, what a fine gun. I can't believe what I've been missing just shooting little handguns all this time

.
I can't leave anything stock, so what I did:
Troy folding M4 front BUIS
Troy battlesight rear folding
Magpul STR carb stock
Hogue grip
Magpul MS3 sling
Omega Tactical rails (what a steal for the price!)
Troy rail covers
Vortex Strikefire Red/Green dot
Magpul B.A.D. lever
Magpul AFG1 angled foregrip (AFG2 was too small)
BCM Mod4 charging handle
Magpul enhanced buttpad
and....red/white crayons
