I ordered a 6.5 Grendel BCG from Bear Creek, after receiving its unmarked and I compared the bolt to a .223 standard bolt. I cannot for the life of me see the difference. Im told its the depth of the bolt face head .136 to .124. is that the only way? Since my upper hasn't arrived yet I cant test . I.m wondering if the .223 bcg will chamber the 6.5 round? I will scribe the bolt accordingly once I comfirm. Any help is appreciated.
