Excellent upgrade - Geissele Super MCX SSA M4 Curved Bow AR Style Steel

Amazing two stage trigger, similar to SSA-E AR15 trigger. Very clean, light and crisp. Installation is same as AR15 other triggers, except this trigger needs an additional metal shroud to be installed. It is an expensive upgrade, but it gives you the best possible trigger. The earlier Rattlers had horrible triggers, trigger upgrade was a must. The newer Rattlers have good triggers, but the Geissele is better.
