I'm afraid I disagree about the BAD lever issues being training related. Then again I suppose with enough training some of the issues could be avoided however in my case I opted to simply remove the lever which eliminated the need. Ultimately the ergonomic foible that ambi bolt releases solve is an administrative one i.e. locking the bolt to the rear manually. This is only ever done when there is no time pressure, I otherwords for administrative purposes on the range. You wouldn't need to manually lock the bolt open in a fight, or during a stage in a competition for that matter.That guy is a douche, buttt... you know the saying. Opinions are like asshole.
The issues of the BAD lever all equate down to training or lack there of. He goes on to point out everything that was wrong with the guy shooting in that video clip. So, it's no shock to what happened.
I have had a BAD lever on my AR for roughly 4 years now and never experienced any issues. Being primarily a lefty shooter, it really helps. Make no mistake that it helps shooting righty as well.
That's my point with the BAD lever, it introduces an additional point of error. Again in my case it was causing me to unintentionally to close the locked bolt during training drills so I got rid of it.In the video clip you can clearly see it was user error. The BAD lever should be pressed in downward action, not back like pulling a trigger.
Yes, it does intrude in the trigger space but not enough to cause an ND, but that's my opinion. I've shot gloved and didn't have issued but I also don't have sausage fingers.
