Nonadjustable trigger - Triggertech AR-15 Special Edition Independence Day Trigger

Description and answered questions from others by the pros say this trigger is adjustable from 2.5-5lbs that’s a lie it’s a fixed 3.5 lb trigger not very happy…for my 308 build I wanted the 2.5 or 3lb trigger that was advertised for a good deal also the reset of this trigger is very weak
