It provides the smoothest cleanest trigger pull on the market highly polished and of the best quality.
It is so highly polished that the lug timing is hard to adjust and make catch. It is also pretty expensive.
The rooler sear is well worth the cost and blows anything like it out of the water with its innovative design. I would reccomend it to some one with the know how to install it and time the gun with it which can be tricky. It is for the supper high end cockers only and not for newbies.
