The Delta 556 contains no chambers so gas is expelled more forward which reduces the concussion to the shooter although recoil mitigation will feel similar to that of an A2 birdcage. The Delta 556 maintains great muzzle control characteristics through the large linear ports. This is a great all around device for tactical, competition or recreational shooters. Includes crush washer. Made in the USA.
