Hey guys,

I am thinking of sbring my draco.  Do I just need the ACE Folding Stock Mechanism w/ Integrated AR-15 Stock Interface?  Is that the only part I need? Or do I also need a receiver block?
Also, any recommendation of handguards and muzzlebreak/flash hider?  I was thinking of getting an ultimak or midwest industries handguard and the Bulgarian KRINKOV style 4-Piece Flash Hider

The receiver block is only for AKs with the tang/open rear trunnion, it goes inside the receiver so that the mechanism has something to attach to.
Since the dracos have a flat pistol trunnion all you have to do is drill/tap the two holes into the rear and the folding mechanism attaches directly to that - no receiver block needed.

If you want to use AR style stock then yes that folding mechanism and a tube and a stock.

I have the MI rail and I like it.  The only gripe is that larue rail clips don't snap on, but that's minor.  

For a flash hider I got a M16 style birdcage threaded to LH.  Works well enough for me.  You'll want something because the Draco puts out a HUGE fireball without a brake or flash hider.  

Enjoy. You'll love the Draco as a SBR.

I just drilled and tapped (10/32) my rear receiver and bolt the stock or folding mechanism directly to the receiver.

As far as a FH I really like the Manticore Arms Nitebrake. Works very well and  is about as short as they come to keep the overall length down.
I also like SLR Single Port Brake

I have the integrated AR15 Ace folding mechanism on my Mini and like it a lot. Magpul covers fit on the MI rail perfectly.  I cut down a CNC Warrior Russian brake for the muzzle (I got the idea from member- The_Punisher).
