Quoted:
I have two quick questions about DSA FAL's

1.)  I am a "newbie" to FAL's but I really like the design.  Are large aperture ghost ring sights available to mount on an FN FAL.  An Example being the large aperture 0.23 inch sights available at http://www.xssights.com/store/tactical.html  

2.)Are DSA FAL's able to have a different compensator than the stock one.  I find I shoot 308's better with certain compensators than others, and I can't see on the website if the muzzles have threads.  

Thank you!
