All engagement parts (hammer and sears) are manufactured from S7 steel using ultra precision wire EDM, hardened with engagement surfaces treated. The cassette is precision CNC'd and Mil-spec hard anodized. The trigger cassette comes assembled and ready to install in any Mil-spec AR receiver with ".154" holes and NO Colt "sear block ." If you have a Colt you'll want to make sure there is no sear block.
"The AR Gold trigger is extremely elegant, innovative and affective design incorporating the modular, drop-in trigger concept. A serious upgrade for any AR15 type rifle and certain to be one of the most important and desirable new accessories in 2009. I'm looking forward to using an AR Gold trigger this hunting season in one of my long range, high precision AR rifles."

Some folks like adjustable triggers, some like them fixed. The upside to the adjustable version is that you can control sear engagement and over-travel, the downside is two fold. First you can set it so that the trigger will not function, or getting so silly cutting the engagement down to near nothing that you risk reliability. The second issue has to the screws walking and the trigger going out of adjustment. If you correctly Loc-Tite the screws, this is not a problem. On the other hand if you fail to Loc-Tite them correctly, they can and will move.
We have a fixed weight trigger in the pipeline, which trades adjustability for being “tamper proof.” This trigger will be set to a weight optimized for use with gloves.
"Spent a week with the AR Gold comp trigger in a Bushmaster M4 here at Blackwater USA and it is now in my own personal weapon. All I can say is."WOW". If you don't have one, get one, no, get two. My name is Hershel Davis and I approve this message.

When most shooters think of a great trigger they are thinking "Crisp." Which is to say no detectable trigger movement (creep) as weight is added to the break point. This is the "Glass Rod" trigger feel. There are some shooters who prefer a “Rolling” trigger. A great Rolling trigger has perceptible movement with no change on weight during the movement, slick with no hint to let off point; like pushing a frosty glass mug across a glass table top with your eyes closed – you know it’s moving, but you can’t feel it going over the edge. This type of trigger is OK for close high speed shooting, but is not optimal when a precison shot is called for. The AR Gold was designed to provide a Crisp feel, with super short reset.
"For those that demand the best in a precision trigger for the AR-15 rifle, American Trigger has cracked the code with the AR Gold trigger, It simply is the final word in 'crisp sear release' for target or competition shooting." - Ken Hackathorn
