That is just a waste of money.

You will spend a lot on it, setting it up and getting it running right.  You will shoot it a few times then be upset you didn't but a 7-9 inch barrel, then it will sit in your safe or a corner, gathering dust for years.  You will never shoot it again.  

You will then move on to the next great idea you have, which will also be a flop and waste of money.

If he's building an aero the barrel gets thicker and heavier at 18 vs 16. The 16 is already heafty. Best to go faxon gunner at that point to save weight. Regardless, a diff of 2" really doesnt have much effect on velocity.

FALs look cool but the ergos SUUUUUUCK. I

nstead of building an AR-10, I’d suggesting buying a basic complete 16” and accessorizing it the way you want. That’s what I did and my Armalite has been MUCH more reliable than either the FAL or SOCOM I owned.

I've got a factory built DSA and a bunch of surplus kit FALs...the surplus kit FALs so far, bore concentricity / flash hider and can concentricity just isn't there Running an alignment rod down the para I was going to use, showed clear contact with baffles and endcaps. I haven't ripped the combo device off the DSA-built gun yet to see if that's good to go yet, but...not sanguine about it.

Plus, with a FAL, you're just not going to use it for accuracy stuff. An AR should hold MOA depending on build specs, barrel, etc...but a FAL just isn't going to do that, not without a lot of luck.

On the upshot, DSA does sell a specific gas plug for use with suppressors...I have one, I just need to find a gun I can actually put it in that won't destroy the can...

OP, the only suggestion that I would make would be to look at other barrels outside of just the Faxon Gunner barrel.  I am not saying that the Gunner barrel is a bad barrel.  I am saying that I had a 20" Gunner on my AR .308 and got somewhere in the 2.5-3 moa range.  Others have gotten better results.  I ended up switching out the barrel for a Rainer Arms 20" Ultramatch barrel.  I got sub-moa out of the box using match ammo with the Rainier barrel.  Yes, there is quite a price difference.  I think the Gunner barrel was about $220-230 and the Rainier Ultramatch was a bit north of $450.

Lots of reports of seriously dinged brass, as well as lots of reports of tight chambers (people popping primers with factory ammo, etc), mediocre at best accuracy - big thread on Sniper's Hide. I'd say it's a work in progress at best...

Don’t worry about the ledge.
I have the same can.
I don’t remember doing any chrono stuff with the can,
But without it-

Compared to a 20inch classic style bolt action,
My 16.25 inch Patrol bolt action or the 16” AR I set up around 2007 or so-

Either typical FMJ 147/150 type bullets or 180 grain hunting bullets were running maybe
2800 and 2500 fps respectively from 20 inch Model 70 pre-64 Winchester,
And around
2700 and 2400 fps respectively from the short guns.

A buddy with a new Savage 110 or something with a 24 inch barrel wanted to chrono it with a bunch of different ammo,
And was pretty pissed he was only getting like
2900 fps and 2500 fps with the extra four inches.

I think 16 is about right for a .308, I’d even prefer shorter. But that’s the kind of shooting I’d be using it for and where I feel it shines, not necessarily yours. I didn’t homebuild mine, but I’ve got an MWS and OBR both in 16” and they’re both very nice setups.

The MWS is a damn nice rifle. It starts off expensive, which isn’t entirely fair since it is very quality, but even then it starts getting a lot cheaper when you factor in the quick pull barrels. My 16” CL turned into a 16” SS and now has a 20” 6.5CM to swap between. They make a host of profiles, calibers, and lengths to make it a very flexible setup.

IMO you can’t build a decent AR-10 for the price of a POF Rogue, and the SFAR is cheaper than the Rouge.

I think that I will get an SFAR. I can say that the Rogue is literally like carrying an AR-15. It’s a bit snappy but still pretty easy to control for double taps or controlled 7s.

I was always a FAL guy, but the Rogue is what the AR10 always should have been.

I have a red dot, light and sling on my Rogue. It’s set up exactly like my 556 carbine.

As a “patrol” carbine it is just about perfect. I have always been a fan of the full sized FAL for my.308 needs. The Rogue is basically an AR15 that shoots .308. No oversized bolt or receivers, 6 pounds empty, it’s a marvel of modern engineering.

I have owned several different large frames starting with a DPMS 24” bull barrel back in the early days. They are pigs for what they are.

That's getting into too long with a suppressor territory for a 308 AR IMO. If you only ever plan to shoot it from a bench, go ahead, but they are chunky and that's a fair amount of weight hanging farther out there that's probably not all that necessary for most people.

I don't care for the aesthetics of the Aero handguard for use with the proprietary upper, but it's rock solid and was a good deal.
