Designed for the AR15 Rifle or Carbine Buffer tubes, our UL Recoil System works with standard weight or Light Weight STEEL* carriers and adjustable gas blocks**.
Drop in assembly, replaces your current buffer.....no Gunsmithing required. Our system is low on recprocating mass and will help produce the lightest and managable recoil for the .223 round available today!
*This system has not been tested with Ti or Aluminum Carriers, so we can not recommend the use of this system with anything but STEEL bolt carrier groups (standard weight or lightened)
**Please note.....this system is designed ONLY to work with adjustable gas blocks and steel carriers, failure to follow this criteria may result in adverse operation and damage to your weapon. You will need to reset your adjustable gas system.
