I have an Ambi selector on two of my ARs and I’m about to add one to my “A4” build. But I’m a lefty, so they don’t bother me. The funny thing is, I’ve gotten kind of used to using my trigger finger to manipulate the selector switch for long enough, that I had to kind of retrain myself to use the Ambi safety, but it is easier for me to use.

Only lose about 10% muzzle velocity between a 16" barrel and a 10.5" barrel...

That’s the primary reason I chose a 10.5” barrel for my .300 Blk SBR. According to the reading I did before buying, the cartridge is more or less optimized for that length - whether you’re shooting subs or supers. I had originally considered a 10.5” 5.56 barrel for an SBR.....and may do one yet, now that the SBR is already registered....but then I started investigating .300 Blk, and decided to do that caliber instead.
