Dear AR building Gurus...
I am going to build my 1st AR, but would like something besides 5.56 (already have that). What other long range calibers are there besides the 6.5 and 6.8 I could build using a 5.56 lower. Will I have to use a different buffer and spring, or just basically change the barrel and bolt? Can I use 5.56 mags with the other calibers....or do I need them modified. Pardon the ignorance.... Thanks in advanced....Grassssshopper
