Well Built EXPO BCG
by Al -
I received my Expo BCG within four days of ordering which was nicely packed in a box. By all appearances, it's identical to my Sons of Liberty Bcg's (more than likely made by Microbest). The Nitride looks smooth and evenly applied, the gas key staking is outstanding and I did not find any visible tool marks or defects. I'll take it out this weekend and make sure it runs as good as it looks. The only thing that I would have preferred was to have an MPI stamping on the bolt, (as shown on the advertised picture) which it does not. Overall, a well built, good looking product. Thanks PA!

Dropped right into a Ruger AR556 upper. I've only ran a few hundred rounds with it but works perfectly

Good first impressions

Good first impressions, good staking and machining. No mpi or c158 marking on bolt unfortunately. No issue when cycling snap caps. Will update the review if there are any issues.
EXPO M-16 BCG
by John -
Although have not had the opportunity to use this BCG yet. When compared to other BCG costing 2x as much, this does appear to be their equal so far.
