RE: What kind of warranty does Simmons carry?
I have had absolutely no problems with the 3 Simmons scopes that I have owned over the years and if you do have a problem - it has a full lifetime - no questions asked full replacement warranty.
Send it back in a good shipping container by UPS, along with an explanation of what is wrong and they will make good on their promise.
My brother had a TASCO that fell apart and before they changed hands, they sent him two scopes and an apology. 2 for the price of one.
He kept one and gave me the second one and it is on one of my favorite 22 Magnum rifles and does a good job.
