Hello everybody! Just wanted to drop a line to say that I was linked up with this site directly from William Graves. I ordered a Leupold Mark 4 6.5-20x50 Ill. TMR 30mm from him yesterday, and received it today!! Less than 20 hours from purchase! This scope will be mounted on top of my 6.5 Grendel AR-15. Its a Alexander Arms 19.5 inch AWS upper with Shilen barrel, which is mated to an Alexander Arms GDMR lower. I had a 4.5-14x50 MK4 on it before this and have shot several .5 moa groups with factory rounds. I believe this cartridge/rifle has a lot of potential and will show with trigger time and once I start rolling out my own loads. I am looking forward to sharing this info and experience with you all here! Thanks again GPS for the great service! -Jason
