For this thread's record for posterity I'd like to provide an update on my rifle in its mature stage. After a couple of years running this rifle I've changed this, tweaked that, added something, taken it back off again. And I believe I have found the best iteration for my needs for this rifle.
Here are the photos:
I decided to go with an Aimpoint because of the constant-on feature. I'll throw my scope onto a dedicated rifle upper in the future.
As for grips, I played with the AFG2, took it off. Put on a Troy vertical grip, took it off. Now I am sporting a Mako magazine port grip and LOVE it. The AFG2 is back on so I can have a forward location for my hand when operating the light.
I put a Streamlight TLR-1 HP with a really focused beam for outside work, if necessary.
Instead of my Hogue rubber grip, I replaced it with a Mako ergonomic grip with battery storage...a must if working with stuff that requires batteries.
I use a 20-round as my primary magazine since it fits in my main safe a lot better.
I also have a BAD lever (not sure it is a help, but we'll see over time) and a Bill Springfield trigger job.
My primary round for home defense is BVAC 64 grain soft points or BVAC 69 grain open tip boat tails. I can't find either anymore so when I run out I guess I'll be switching.
Though it isn't pictured, I keep the same Vickers 2-point QD sling attached while it resides in the safe.
This has been a labor of love and I have no idea how much I have put into it. It has been way cheaper than simple M4's have been seen for the last few months...and it's MINE.
