Is toolcraft a good BCG?
Toolcraft uses some of the best available 8620 steel for their carriers.

This makes for a BCG with a very smooth finish and little or no machining marks.
What is the difference between an ar15 and M16 bolt carrier?
The main difference between an AR-15 and an M16 lies in the lower receiver. M16 lower receivers have a third trigger pin hole for the auto sear, while AR-15 lower receivers do not. M16 lower receivers may also be milled to slightly different dimensions to accommodate the full auto fire control group.
