Product Description The LanTac Drakon (Dragon) AK Muzzle Brake is built to high quality standards and uses a patented design to improve recoil management and reduce muzzle rise. Its Short Energy Pulse system is designed to shorten the recoil impulse so repeating shot energy cannot overlap and disrupt the shooter&&';;s sight picture, helping keep shots on target during rapid strings and full-auto fire. This model features an AK M14x1 left-hand thread pattern and is Dead Air KeyMo compatible, and includes a timing shim set for proper alignment.
