Call Sinclair. They may not be the cheapest-but their sales people on a scale of 1 to 10 are a 10. The next best would be Gamalial Shooting supply. Talk to Jeff-he is a 10. All mail order places come in around a 2 or 3. The guys at Sinclair will not lead you astray. They will tell you the truth. I have dealt with them for years, and they are first class. I have learned alot from them, because they will take the time to explain things to you. Call them and you will see why I say this. Tom.
