    Bought an OEM blue and a #15 red, so far the #15 red works great with their fluted stainless guide rod.

    I like the fact that they recommend the red spring because I've tried the blue and the red and the red is definitely the way to go

    Fast shipping, and excellent customer service. Red recoil spring was out of stock I reached out to them they put it back on the website the same day. Order came very quickly. I’m very impressed with this company and I will use them again and would highly recommend them
