    Do I Need a buffer spring

    I finely got the chance to shoot my stamped poly mak90, Loved it. I noticed before hand that the rear trunion had some impact marks. I put some tape on it to see if it was still hitting. After a few rounds I checked and still hitting. I am told this is an early mac 90, is it time for a new spring? If so any recommendations.

    Get an Mcarbo spring. They are consistent and last longer So far every one I have checked the rate on has been consistent because they its a cold wound spring. The ALG springs I checked were not. Not by much but Id take a consistent spring of one that is not.

    Fig, if you get the Mcarbo spring, would you be able to do before and after spent case distance measurements? I'm very curious to see how much of a difference it makes.

    Does anyone have any concerns that the mcarbo with 15% extra power will start damaging the front trunnion?

    Good question just try another stock spring.
    Its normal for the carrier to make contact but that seems excessive try one of these

    No. That's flawed logic. Even a recoil spring that's too heavy will not cause such damage. A carrier going back too fast is what can damage the rear trunnion.

    I ordered the mcabro extra power recoil spring today. They were very quick to reply to some questions I emailed them. I will try to get back out to get some spent casing distances on the stock spring. I will get some comparison pick of both springs when it arrives and the new ejection distance.
    The other mfg. has not responded to my questions.

    Mcarbo is a good company.
    The other one is resting on it's laurels.
