Sturdy, well made spring set
There isn't a whole lot to say about springs in a review, but you can see small details in this set that shows the care and research that goes into Rifle Dynamic's products. Nothing of theirs is ever sharp or burred, the ends of the main spring are evenly flat and leveled, and its all made of good quality steel as far as I can see and feel. The hammer spring, for example, is very well made in the previously mentioned regards. Making wound springs in the Russian style can be notoriously difficult but these seem to be well made. Small details, but with stacking tolerances these are the things that add up to a quality build or not. Shipping was quick, as always.
