I am in the final stages of decision making over the purchase of a .308/7.62 rifle, and leaning towards a DS Arms 18" Para Congo. I've also put some time into research and evaluation of an AR-10. The AR-10, being more readily available/common is the weapon I've put some actual hands-on range evaluation into - I have not located anyone in my area who had a DS Arms or other FAL they were willing to loan out...
As far as gas-operated weapons go, I have lots of AR-15 experience, as well as the indirect/ARGO gas-operated Benelli M4 shotgun. I understand the indirect, short-stroke/vent to atmosphere operation of the FAL, which is largely appealing - especially for this class of weapon over the Stoner system in an AR-type rifle.
So, while I'm asking a group with probable bias towards the FAL... given price was not your concern, and you wanted long-term reliability, reasonable accuracy, and serviceability out of a .308/7.62 weapon would you choose the FAL over an AR-10?
