I was wondering if it had rails on all sides of the barrel and if the top rail was picatinny?

Jesse, yes, the top full rail is a Picatinny Rail. The sides and bottom have KeyMod Slots that you can attach KeyMod Picatinny Rail Sections to for accessories. Located here : https://www.budsgunshop.com/search.php?q=keymod+rail+section&type=

Jesse, The top of fore end is complete pic rail. Sides are Key Mod slots to apply pic rails. Here is entire set for under $10---------https://www.budsgunshop.com/product_info.php/products_id/714015512/bcm+gunfighter+kmod+rail+panels+blk

The top rail is a full length picatinny rail, the sides and bottom have Keymod slots for adding other accessories or rail sections.

Is this buffer tube compatible with the SB Tactical braces?

Yep, William, you can just remove the blade, and install the SB brace. Just don't install a 'shoulder stock' - if you do, you've built a Short Barrel Rifle, which requires a Tax Stamp to build.

William, yes Sir it is. The DB10 uses a Mil-Spec Buffer Tube.

I know it says AR Pistol but the wording in the description has me thrown off a little. Is this a pistol or am I required to do a tax stamp for this firearm? Is it a brace or a stock?

Joshua, this is classified as a "Pistol" with the 13" Barrel and the Blade Brace Sir. As in "Handgun". I'd like to see one try conceal carrying this. Lol

Does this come with a 1 in 10 or 1 in 12 twist barrel?

Samuel, 1 in 10 Twist Rate 13" Stainless Steel Barrel. This rate will optimally stabilize bullets from 155 to 220 grains.

Barrel has a 1:10 twist rate - a good general use barrel for pretty much the entire range of 308 bullets.

Can this use FN FAL 308 mags or M1A1 mags?

no it uses AR 10 style magazines here is a 20 round mag https://www.budsgunshop.com/catalog/product_info.php/products_id/714007075/magpul+mag291-blk+ar-10+pmag+gen+m3+20rd+308win%2f762nato+black and a 25 round mag https://www.budsgunshop.com/catalog/product_info.php/products_id/714014357/magpul+pmag+m3+m118lr%2fsr+762+25r+bk

Samuel, I have this same rifle (In FDE) and the Magpul magazines are tight. It comes with a metal SR-25 Pattern AR-10 Magazine and they slide in and drop free way easier than the plastic magazines. https://www.budsgunshop.com/catalog/product_info.php/products_id/713078099/cpd+magazine+sr25+762x51+20rd

No Samuel - it is an AR-10 style rifle and uses AR-10 magazines. Use Mag Pul PMAG MAG291-BLK or Mag Pul PMAG MAG577-BLK.

WHAT IS THE THREAD COUNT ON THIS PISTOL ?

Juan, this barrel is threaded 5/8 x 24.
