I'm afraid you've walked into a giant nest of large-frame AR enthusiasts with your question, and by far the majority of experience here has been to the contrary of what you're describing. It would be a little easier to address your issues though if they were described in a little more detail. Having said that, welcome to our forums, I think your time spent here will be very enjoyable. There's a wealth of information here on the forums, and a helpful, practical attitude is prevalent throughout. Enjoy!
