Toolcraft BCG 5.56 DLC Grey C158 MPI Bolt OCKS Screws BLEM GRADE B

NOW WITH UPGRADED OCKS SCREWS !

I have a few BCG's that were shipped from Toolcraft to me as new, but hand picked out a few with a rougher finish or small blems.  Therefore I'm selling a few of these with small blemishes that do not affect function.  All BLEM products are offered as 100% operationally guaranteed by Toolcraft but are non-returnable for cosmetic blem reasons.  I hand inspect each BCG prior to ship. Due to the varying nature of the blems, repeatability really can't be anticipated.  I do grade them with my internal system.  Please note all "blems" are sold to me "as new" by toolcraft.  But BCG's are manufactured in a manual-multistage process, so some handling wear does happen.  My pricing on blems won't be consisten.  I post small quantities of similar grades of blems and adjust the price accordingly.

THESE BCG'S ARE MY BLEM GRADE C
Grade "A-"  are  pretty much non-blem. BCG's are manufactured in a multi-step process and a very minor scuff or machine marks under the finish, in non-critical, non contact areas are normal.
Grade "B+ to B-" are sold as "B" blems.  You may or may not be able to see the blem, but the blem won't affect the performance.  
Grade "C+ to C+" are sold as "C" blems.  You will be able to see the blem, but the blem won't affect the performance.  Grade C blem is typically due to some rough handling in manufacturing or shipping.
Grade "D" are bad blems that go back to Toolcraft.
