Re: Timney AR15 Weight??
For openers, we love machinists on this forum because it's guys like you who've helped us over the past couple of years to create a number of the custom components that allowed us to get the most out these crossbows, so many times I'd appreciate being able to bounce new ideas off somebody with your type of background skills and expertise, so it'll be a good trade off in the end.
Over the past 15 years I've had both of my shoulders operated on and then rehabilitated, so I know what you must be going through. Mine were both "Frozen Shoulders", just several years apart.
You'll meet numerous others on this website that all have a great deal to offer in terms of knowledge and suggestions, so keep and open mind to all of them. Some people may publish more articles than others, but those who don't are no less knowledgeable than those who do, they just might not be as interested in writing about everything they know.
Although we have an extensive forum of threads that should guide you through many different steps in adjusting and tuning your crossbow, once in a while, we might need to direct you to an article or two that exists elsewhere, but for the most part, you'll find everything you need in the older pages of this forum.
I'll address you question about about scopes or sites later this evening after dinner when I have more time. Also, please look for any input that comes from any of the other members of this forum because their advice is every bit as good as anything I can provide.
