Toolcraft Nickel Boron 158 Steel Bolt Carrier Group

This Nickel Boron 158 BCG from Toolcraft features an MPI bolt and M16 carrier, and comes with a lifetime warranty. Built to military specifications, it stays true to the Toolcraft name of quality, durability and best-in-industry. The bolt is made from mil-spec carpenter 158 steel, shot peened and magnetic particle inspected, while its carrier is made from 8620 tool steel. All components are pre-polished before being plated by UCT and then polished again for a high shine.

The RTB team does quality checks on every bolt carrier group we receive, and we inspect everything before putting it up for sale. We don’t blend Toolcraft carriers with random bolts or use raw carriers. Be wary of other companies that purchase just carriers from Toolcraft and then assemble BCGs with random bolts! Even worse, some companies get their carriers raw and use inferior plating or coating. Contact us if you have any questions about this Toolcraft BCG, and save when you shop at Right To Bear. Don't forget that BCGs from Toolcraft come with a lifetime warranty!

Buy this BCG! May 1, 2018
Reviewer: MWF from United States  
ToolCraft has always been a quality manufacturer & they have built a solid reputation on their products.
This BCG is a keeper. Quality workmanship,beautiful finish that will take all of your abuse.
NB finish is easy to clean.
Finish it so smooth you probably don't need to lube it.
I have multiples of this very BCG and recommend them to everyone. You can spend more , but your not going to beat it in performance or quality.
And to make it just that much easier to decide ,RTB's pricing,shipping & Customer Service seal the deal.
Buy it! You WILL not be disappointed.
ToolCraft is thumbs up , 5 star product.

Very nice BCG January 21, 2018
Reviewer: Matt from Vail, AZ United States  
I purchased this Toolcraft NiB BCG for my first AR build and I think I made the right choice...at least I know I purchased it from the right place (RTB).  The BCG is beautiful: Very shiny, smooth and appears to be properly staked.  I haven't tested it out yet, but I don't have any doubts about its functionality. If any issues arise, the lifetime warranty will cover.
RTB's customer service is also one of the best i've dealt with.  RTB will be my first stop for future parts.  Plus, they are veteran owned and i'm happy to support.  
*update* I ran about a 100 rounds through it today and it was perfect. No issues whatsoever. Cleanup was very easy.
