“Excellent quality build. Was a little disappointed cleaning after 150 rounds. Before shooting I took it apart to inspect everything and lubed it up good. Was surprised how much the carbon built up after only 150 rounds or Hornady ammo. It was not the easy clean up I have read about with the Nickel Boron.”
“The Toolcraft Nickel Boron BCG is a high quality piece, gas key is secured and the finish is first rate. I use very little lube on it and it just slides!”
“The NiB BCG was also a nice upgrade. 300rds on it this weekend and just a wipe of the rag and it's clean. I'm going to have to upgrade my others to the same coating.”
