I hear a lot of people say that an FN FAL isn’t very accurate but my DSA FAL shoots 3/4” groups at 100 yards with an optic. I just wish it had better iron sights and didn’t have the stupid AWB era muzzle brake so I could thread on a suppressor. I’m looking at just replacing the barrel with a medium weight threaded barrel.
FALs are more accurate than their reputation and FAL irons are excellent battle sights, especially for snap shooting and for tracking moving targets.
If your FAL is shooting .75 MOA, do not even touch that barrel much less remove the brake or change the barrel.
Medium weight barrels do not shoot 0.75 MOA.
Buy another FAL to suppress and keep this one as it is and never get rid of it.
In fact, consider being buried with it when you pass away.
