I plan on building an A2 style AR this winter and am starting
to plan out parts I'll need.  In the bolt & carrier arena, I came across
this one by Wilson Combar for $110, which seems pretty reasonable...

Wilson Combat

anyone have any experiences with this one or can they recommend one
that may be a better bang for the buck?  Yes, I am in actuality a finatik when
it comes to quality and would rather spend a few extra $ for a part that has
better reliability/functional properties.  From what I've read so far the Wilson/RR
(16" CAR/Mid Entry) barrels are highly regarded so will most likely look to mate
a bolt/carrier with one of these.  Opinions?
Thanks,

I wonder who makes them. It doesn't say if its their ow bolt carrier or someone elses
