Product Description The Spike&&';;s Tactical Dynacomp Extreme is a muzzle device engineered to reduce recoil impulse and muzzle climb for faster, more controlled follow-up shots. Its design balances muzzle blast along vertical and perpendicular planes to help limit rise, while restricting forward energy to reduce rearward recoil. Ball-dimpled ports promote smooth gas expansion and rapid heat dissipation, and the reinforced 0.25" thick front is built to better withstand demanding use. This model is threaded 1/2"x28 and intended for 5.56x45mm NATO platforms, and includes a crush washer for installation.
