We can also UPGRADE the TRIGGER to a Rise Armament RAVE 140 or a Timney Impact Trigger. Great option if you are looking for a lighter and more crisp trigger pull.
An OPTION is COLOR. We can change the receiver and handguard to FDE (FLAT DARK EARTH) COLOR (see pictures).
We also offer an OPTION to add a 80% 7075 T6 Aluminum Milspec Lower Receiver (Raw or Anodized) to your kit.
NOTE: We recommend E-LANDER 458 Socom Magazines for this caliber.
