Hi from Missouri - Rzrbac - 10-23-2021
Just found this forum while reading about the 6.5. I intend on building an upper in 6.5 Grendel for hunting. I havent deer hunted with a rifle in several years. My weapon of choice has been a bow for awhile now but lately got the urge to use a rifle. Ive always been a bolt action guy but I have a couple of ARs I occasionally shoot. I feel like I need to sharpen my marksmanship skills and thought an AR platform with an inexpensive cartridge is the ticket. I considered buying a complete upper but I like the idea of building one to my own likes. Im hoping to glean some valuable info from the members here.

Welcome to the clan, Rc, from the great nation of Texas! There are a number of threads across these pages on "roll-your-own" uppers and lowers. Read well, first! Put your money in the barrel and then be sure to true your receiver. Once done, the results are often amazing. A mediocre barrel properly assembled onto an upper receiver can often outshoot a high-dollar barrel poorly assembled.

Thanks for the advice, no idea how to true a receiver. Ill research it but Im still reading up on barrels. Leaning toward Odin 18 at the moment.
BTW, love Texas, visited a few times and the people are awesome and the brisket was amazing.

The main consideration is the barrel to upper interface. If your upper is billet then it "should" be machined true. However, on many forged uppers, the end of the threaded ring where the barrel is secured will not be truely perpendicular to the axis of the barrel, that is to say that the barrel, when fully seated either will not be perfectly straight with the centerline of the receiver or may be riding on a high spot such that it rocks very slightly - I've seen both. There is a tool that drops into the snout and, when used with valve grinding compound trues that surface. I only use forged receivers and have assembled or helped others to assemble more than 50 MSR's and the only manufacturer that I have encountered where they start off true is Bravo Company. There was an excellent article by Peyton Sweeny in Guns and AMmo Mag a few years ago about this process and the tremendous accuracy improvement this truing process made to his MSRs - highly suggested reading for anyone building their own.
The first Grendel that I built some years ago seemed ideal, but... When I went to the range with it, as the distance to the target increased the POI shifted to the left. After a lot of frustrating discussions with the guys around me, it was discovered that the barrel was actually slightly canted to the side. The "snout" was not faced off properly.
