lightweight primary arms, 18-20 grams pin weight, 417 ramps, clicker 3 to start, 160-320 primary spring, Toss the stock secondary it will flat wear you out and to my experience never work right. Team L/W secondary if you choose to buy one I will give you the scoop on the set up. I do have a spring for the stock secondary that kinda worked- maybe alittle- that dyamojoe sent me way back when, if you want I could check the paint and get back to you. Good luck
