Guys,

First of all, new to the forum, hello everyone.

I've been wanting a Mark 11 for a while now, and decided that rather than wait for military demand to go down, I'm going to build an AR10 version.

My main question right now is what model base gun should I purchase? I'm considering the AR10AR in either the carbine or 20 inch platform. What I plan to do is at a later date, add a high end barrel and Larue rail, along with a PRS stock. I also plan on purchasing either Armalite's adjustable gas system, or someone elses. I haven't really researched that yet, so I have no idea what one. I do plan to purchase an Ops Inc silencer. We'll talk scopes at a later date. This build will probably take me a while, but I want to get the base gun purchased.

Is there any difference between the Carbine and Rifle version, or is it just the collapsable stock and barrel length? Feel free to comment on my choices, just give me an explanation why you would or wouldn't go the route I've chosen.

Build:
AR10, either carbine or 20 in rifle
10 Armalite Gen 2 20 round magazines
Larue AR10 FF rail system.
Pac-Nor 20 inch Barrel from Adco (considering Noveske 21 inch)
MagPul PRS Stock (considering VLTOR modstock)
Knights Armament 2 Stage Trigger
Kinghts Armament front and rear buis 600m
Sierra Precision AR15 Grip
Ops Inc. 12th Model 7.62 Silencer
