Don't know much about these FAL style rifles. It's marked:

FA 91     308 Cal
Federal Arms Corp.
D.C. Industries, Inc
00123XX

Looking for any info I can. Rifle is in Good condition, Good rifling with fake suppressor at the end. (not sure if it's detachable) Just wondering how much should I pay for it. Anyone know where I can get mags for it? Oh and is it a HK 91 clone? thanks for any info.

Oh and it's a Flat top reciever, btw.
Another thing, when looking for mags or parts should I look for metric or standard?
thanks again

 Sparsky, it's HK91 clone.  I say about 400 bucks or a little more.
  HK91 costs about 2K or more, depending on the condition.

I think I've got exactly what you describe. Mine is a G3 instead of a "91" model. I'm unsure what exactly the difference is.

The Federal lower is alumunim instead of stamped steel or whatever it is they make the "real" ones out of.

Trigger leaves a bit to be desired, it's kinda mushy. Groups are about 4-5" @ 100yards using mil-surp ammo. Reliability has been perfect for me, not one jam or misfeed.

Mags are easily found at gunshows.

The ONE thing I love is there's NO GD gas adjustment as on a FAL. Just load that sumbitch & shoot it!

On the downside, since I bought my AR-10 I haven't once shot my G3. Huge difference in accuracy & felt recoil using the same ammo. Of course the AR-10 costs twice as much!  >gg<
