I have been considering attempting a custom AR build using an 80% lower and building a gun just for my use in longer range accuracy.
If anyone has comments or experience I would be happy to hear it.

I take it you're doing this for the challenge, rather than any other reason.

The challenge and the education as well as the pure fun of it.
I already know it is not going to be cheaper than just buying one off the shelf but I can build it the way I want it with my own two hands.

I did learn to assemble AR lowers inside a big, clear plastic bag. It'll save you a lot of time and aggravation when those damn little springs and pins go flying...

I'll remember that trick... right after I lose my first spring and detent.

How often do you have to come out for air?

Right after you get your last spring and detent locked in place mate.

As funny as that sounds I wonder how many people would wear a bag.
Never underestimate stupidity.
I can make the special tools to put in those springs and detents. I have plans for roll pin starter punches but I am going to have to buy the special wrenches for the buffer tube and barrel nuts. I think I will invest in the vice blocks too, just to make it easier on myself.
I do wonder if I will want another one after I build one... I hear it can be addictive.

Bushy, I run an air hose into the bag...

Paul, I've put together a couple of lowers for purchased AR-15 uppers. Now I've got another whole rifle scattered on the work table and most of another in a box underneath. After I finish those I believe I'll try an AR-10. Is it addictive? Well...

Hey Pumpkinslinger,
How heavy can you build an AR10? I don't want to shoot a lightweight 308. I like 10 pound rifles, is there one that comes close?

DPMS Panther .308.

My .458 SOCOM AR-15 weighs about 8.5 pounds, empty with scope. That's almost exactly the same as the Marlin .45-70, with scope. According to Wikipedia an AR-10 weighs between 7.5 and 9 pounds empty, w/o scope. So I'd think making it weigh 10 pounds would be easy.

I have flip-up iron sights on my AR 10 (no scope). Add the 20 round magazine and it will weigh right at 10 lbs.

I know because I just weighed it with a loaded magazine.

You guys get to play with all the good toys...

Yes mate...and Bushy’s AR10 is a real pussy cat to use as well...and damn it’s accurate.
