Hey all. Just tried to installing my 5100s tonight. They didn't fit!
I dont know if anyway else ran into this problem, but the diameter of the piston is larger than the inside diameter of the spring hat. I grabbed a caliber and measured out of confusion. Sure enough, the diameter of the 5100s were about 1/32" larger than the stock piston.
Not sure if this is an isolated isue with me or not. Some insight would be much obliged.
And i broke a spring compressir what a night lol
