Let me tell you the M14 and the FAL will tear you up if your shoulder was sore at the range the other day these will put a hurt on you especially a non modified m14. The FAL accuracy again sucks much harder weapon to shoot but tons better then the AK. Keep in mind I have no civilian experience with these or any weapons all weapons I look at are strictly from a combat use situation.
Weight thing is a legit concern we carry enough out there and when you're rocking 23 30round mags it adds up fast LOL. I really wish they would of made the SAW conversion service wide I think everyone could of benefited from the larger rounds in that conversion not just a select few us that got them.
