Doug Braker ,I just took 2- 90T to him in august . replaced springs did the updates . he told me gun would be ready for another 50,000 rounds . that it would be like new . the gentlemen is as good as his word.
I understand,Doug Breaker was instrumental in the design and mmfg. of the 90 T. As he was working for Kolar when it was developed. As far as I know he is the number one expert on these fine shotguns. Has helped me more than once with minor problems. He in my opinion is "The" go to guy. J.W.
Send it to Doug Braker. The top lever spring may not be the only issue. He can check to see if the gun needs the locking block update as well as the forearm update. He rates are very reasonable. He's the best there is. Bob
Clayshooter100, I agree with the kudo's for Doug Braker. Something nobody else mentioned is, if you prefer, contact Doug and he will e-mail you instructions to DIY and most likely sell you a spring as well.
