DSA make a bolt on unit for them @$300. You really need to consider WHAT you want out of the rifle mate, if you are looking for a accurate and reliable battle rifle the FAL is really hard to beat, if you are looking for somelike an M4 on 'roids you really start to negate the things which make the FAL what it is and what makes it so popular with people who have carried such tools professionally. I guess you have to go back and look at just what you are trying to achieve.
