Good greif, the FRT is a legal document that Troy used as a starting point and then Troy clearly made many changes in the actual rifle.
Here is my, rather nicely put together, and well shooting BCL 102.
Note the following changes from the Troy 102:
All the furnature is different, but nobody cares.
Gone is the BCL Ambi bolt release, and the trigger guards also changed, so the lower is different.
The upper is similar but again different, notice the different lines.
The handguards are very different.
The barrel is completely different.
Most importantly, but not shown clearly is the that BCG is very different in who makes it.
It was the BCG and extractor issues that gave most people issues with their BCL 102.
I was lucky enough not to have any issues with my BCG.
So while both rifles follow similar AR10 patterns, claiming a Tory is a BCL is, in my mind, like claiming a Norinco AR15 is the same rifle and my Colt Canada MMR.
With no disrespect to BCL as they have given me no reason for complaining. The fit, finish, and tolerances of my BCL 102 upper, lower, and handguard are spot on, and on par with my CC MMR.
