Unbeatable Reduction in Muzzle Rise with Less Aggressive Venting
The APOLLO S from Ultradyne provides competition level recoil reduction and muzzle control. By using a scientific approach and studying thousands of recoil events, Ultradyne engineers have struck a balance between extreme recoil reduction, virtual elimination of muzzle rise, and less aggressive venting of gas. The Apollo S is perfect for shooters who want drastic recoil reduction with less perceived blast. The perfectly sized 5-Port design evens out the recoil event which produces an ultra smooth shot like no other compensator. A timing nut is included for easy installation.
