Sorry for the delay, I just picked my AAA Clasics .308 Multi Caliber Lower from Mitch Butler this past Thursday. He had just picked up about 100 "MM10" (Multi Magazine) Lowers from his plater.
The finish is Hard Anodized, which is a durable conversion process that wears very well.
He also had the first run if "BAR 12" 30-06 length Lowers - they exist!
He is in the process of moving forward with Uppers for both length guns.
Getting back to my gun..
I opted for the "standard" DPMS-type Magazine Lower, as I have several of their mags and am content with that configuration.
Mitch supplied me with his, made in-house, hardened stainless TakeDown Pins, Bolt Stop, Mag Release & Plungers.
The Ambi-Safety Selector is still in process and I will get that later, although he supplied me with a generic Selector. He also provided the springs needed to build up the Lower.
As you should be able to see in my (hopefully) attached photos, I just installed standard trigger/hammer parts (from one of my '15's) for the initial build. The Upper is a DPMS 20" .308 1/10" Twist, with Levang Comp & DPMS Carbon Fiber Floating Handguard. I will eventually upgrade to MagPul Adjustable Butt & Grip.
The parts went into the AAA Lower without any drama. And the DPMS Upper mates very nicely.
I'll get you an update, after I get to the range - in about a week.
Oh, I have his permission to give you his phone of 817-572-3306.
Here are some additional notes:
1. His Mag Release Button has concentric grooves on 1 side & checkered on the other - pretty cool.
2. Mitch starts the Bolt Stop Tension (roll) Pin in his Lowers (anyone whom has assembled a stripped lower would probably appreciate this).
3. A hanging point for some of you may be that because of the beefy Mag Well and Mag Button "Surround", you will not be able to utilize Hammer Pins that are retained with e-clips (Trigger Pivots are clear). He told me that he MAY, in the future, make a cut that will clear the right side e-clip.
For now, he has several hundred finished Lowers and they are past the point of that modification - contact him for more info.
