I am looking at several options for taking a ar 15, and running Grendel brass with 6mm 105's. On ar15performance.com they have this 20" 6mm AR-P SPR profile barrel- 4150 CMV Sale Price: $290.00 (8 twist) . I'm not sure about this product or the bolt he offers(any suggestions) I don't have any contact with him. Is this a legit place? PTG offers a reamer for 243 LBC with a .273 neck and .098 free bore. I can have a gun smith make my own barrel this way. With this reamer in 243 LBC I can use 6.5 Grendel dies and 6mm ppc dies for the neck down. I'm wondering with this reamer if I will have to trim brass(I don't want to have to trim obviously) 6mmar.com has some cool stuff, its pretty high and you cant order just barrels or pick exactly what you want, that's the negative for me, but the upper seems to be very nice The dies are custom dies and they are a total of 300 bucks. I'm wanting to build a mega sbu side charging upper if I don't go with a Whitley(6mmar.com) What bolt do you guys recommend for the Young Manufacturing side bolt carrier, with the mega upper. I assume I can run any 6.5 Grendel bolt? Correct? What is the difference in 6mmar and 243 LBC?
Does anyone have any insight in general or suggestions on the whole process? Thanks
