I own both. Bought the ultradyne apollo first. It just about totally eliminated jump/ recoil but the blow back suffocated me as well as fogged the scope. Replaced it with the Lantac dragon which has no blow back and provides adequate muzzle stability. I really wanted to like the Ultradyne but....I don't own any suppressors, so no brake that will accept 1. If forgoing the hiding of flash and only wanting reduced recoil and barrel movement I'd recommend only 2, ultradyne and lantac dragon (depending on which 1 it does accept a suppressor). I've used both on barrels from 11.5 to 24" w/5.56 nato and hornady 75bthp's superformance ammo.
