Ultradyne offers different Muzzle Devices that redirect gases at varying angles to provide a muzzle device option for every shooter. With this being said, it is important for the shooter to understand their proximity to the Muzzle Device itself and determine if the RGP will cause problems.For example, the RGP on a traditional M4 16" barrel with a combat forearm equipped with an Apollo Max will bypass a 5'9" shooter totally, however the RGP on a gun that is equipped with a fully extended hand guard and 20" barrel could possibly impact the arm of a 6'6" shooter that uses a fully extended arm style grip.It is truly up to the shooter to determine the ideal set up for an acceptable Redirected Gas Path (RGP) for the ammo, firearm and individual shooting style to be used.#html-body [data-pb-style="62DF828BC96D7"]{justify-content: flex-start; display: flex; flex-direction: column; background-position: left top; background-size: cover; background-repeat: no-repeat; background-attachment: scroll; border-style: none; border-width: 1px; border-radius: 0px; margin: 0px 0px 10px; padding: 10px;}#html-body [data-pb-style="62DF828BC96E4"]{border-style: none; border-width: 1px; border-radius: 0px; margin: 0px; padding: 0px;}
