You're right, pointing a firearm that you are in control of or were recently in control of(in the case of transitioning) is a violation of the F4 rules. Nowhere in the F4 rules does it say anything about the firearm being physically loaded or not. Remember, rule one states that "all guns are always loaded and should be treated as such." That being the case, it doesn't really matter if the firearm is physically loaded or not. Control the muzzle and there is no potential for bad results. Which means clearing the firearm prior to transition is not necessary. I know what some will say. A hot rifle/pistol being placed in a barrel, on a table etc has the potential for ND. The same potential exists and even more so by requiring an adrenaline pumped competitor to operate controls and show clear. Showing clear also fosters the mindset that "its unloaded, its ok if it sweeps someone or something I'm not comfortable shooting". Which is a direct violation of F4 rule number 2. F4 rules number 2 and 3 cover all firearms when not actually being fired. Don't point them at things you're not comfortable with destroying/shooting and keep your finger off the trigger until your sights are on target(an appropriate target as defined by rule 2).
The potential for a rifle to fall and discharge is extremely low, but it is a possibility. Where and how a competitor dumps his guns during transitions is the biggest factor for dropped/falling guns. Appropriate transition locations/methods will prevent this.
As for ND's. They don't occur because someone violated the 9 rules of ACTS and PROVE. They occur because people violate F4 rule number 3. "KEEP YOUR FINGER OFF THE TRIGGER UNTIL YOUR SIGHTS ARE ALIGNED ON TARGET." Someone gets hurt because they also violated rule 2. I guess you could say they violated rule number 1 also, but that goes without saying. incidental injuries or damage are often a result of violating rule 4. Damage to houses, barns, cars, etc are a direct result of violating number 4.
As for training for the majority of AR's out there and training for real life. I'm inline with the mentality. It makes sense and saves me money.
So let me get this straight. The BAD is advantageous for two reasons. It aids in faster reloads, and it aids in locking the bolt to the rear for malfunction clearance or showing clear. Your rifle with BAD lever installed will no longer lock the bolt open on last round, so the critical and most often used feature of the BAD is nul and void because the BAD is installed. From the competitor side of things, your manual of arms now takes more time not less because of the BAD. So the next question is. Why do you keep it if it induces more problems than it solves?
