A really nice trigger at an extremely great price. If VALUE is what you look for in a part, then this improved version of the classic single stage mil-spec is for you! Mine came with the anticipated ‘S’ markings, just like all of the other versions you can find marketed elsewhere, but after shopping around quite a bit, no one else beat the price offered on TT. This FCG installed in just a few minutes with a little help from YouTube seeing as this was my first trigger job. The action feels smooth and the trigger pull may even be a little light compared to my rifle with the same trigger that I sourced from another retailer. Overall, I’m super happy with this purchase - maybe my favorite upgrade so far.
