Hi all,
Just wanted to give a thumbs up and share my experience with Olympic Arms Repair center. Had a second or perhaps third hand Olympic Arms 9mm upper which was doubling - picked it up used a couple years ago. Excellent shape, but it was the 'older style' carrier design with full carrier key.
Contacted gunsmith Andy Wilson of Olympic Arms via their website and advised him of the problem and asked his suggestions.
After a couple timely emails back and forth we finally determined that the firing pin return spring had taken set. I certainly expected to pay for any parts and/or repairs that would be needed due to not being the original owner.
I was very pleased to receive and email from Andy stating that the upgraded carrier key and a new spring were on their way to me - at no charge.
Certainly nice to see that they have an such a devoted 'smith' in their ranks willing to answer all my questions and ultimately provide me the parts need to get the upper running again.
Thank you Olympic!
