Notes:
1.  All Toolcraft bolts are MPI inspected, but not necessarily marked MPI.  WCArmory requests MPI marked bolts but Toolcraft can not guarantee that all MPI inspected bolts will be MPI marked.  Email WCArmory for this disclaimer from the Toolcraft Operations Manager.
2.  All BCG's are ordered direct from Toolcraft with the coating applied by Toolcraft's sub-supplier.  All coatings are purchased and furnished direct from Toolcraft, and their full warantee is obviously valid.  
3.  WCArmory has been selling Toolcraft BCG's since 2009.
