For the price It does all right

For the price you pay it is okay. However they do the nickel boron coating tho isn't that great the bottom guide where the hammer slides across got ruffed up for some reason.. but I polish the hammer face an smooth and repolished the bottom part of the bolt carrier and it works fine
