Toolcraft Nickel Boron BCG 224 Valkyrie
Free Shipping on all Toolcraft Bolt Carrier Groups!
Your 224 Valkyrie build deserves the best bolt carrier group money can buy. This 224 Nickel Boron BCG by Toolcraft is the highest quality BCG on the market today.
Nickel Boron is an extremely durable finish with self-lubricating properties so your AR15 cycles smoother and requires less lubrication. Toolcraft has the Nickel Boron finish applied by UCT Coatings of Palm City FL, the same company that applies it for Fail Zero BCGs. Called EXO Technology, this is a patented process that applies a Nickel Boron finish so durable that it is specified on Army 81mm and 60mm mortar tubes, Blackhawk helicopter hoists, and for hard use applications on some Navy ships! IMO, this may be the ultimate upgrade to the All-American AR-15. And it looks good too!
