Primary Machine recoil springs are intended for use only with our fluted, stainless guide rods.
Blue: OEM Equivalent
Weight recommendations: We recommend a 15lb recoil spring for every day use and 13lb for suppressor use.
Bought an OEM blue and a #15 red, so far the #15 red works great with their fluted stainless guide rod.
Looks good very hard to put in
Excellent flat wire spring and for only $8? I’ll take that all day!
Excellent fit, I ordered two of them 15lb and factory lb. I recommend this to anyone wants them.
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
Looks and works just as described. Excellent customer service. And fast shipping
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
