Order arrived in a timely fashion.
Overall impression is positive... finish is consistent, milling clean, threading is accurate.
My Nano Comp does not have the 7.62 engraved on the side as pictured above.
Did not come with a crush washer... not a huge deal as it was not advertised as such but the S&J 5.56 versions at my gun store do come with.
Only one range test so far...
- Substantial flash reduction
- Substantial noise reduction for the shooter
- Minimal recoil/flip reduction... (estimate 10%)
Overall I'm a happy customer... would have been VERY happy if it included the crush washer.
ADD: Also picked up a S&J scope rail which I am very pleased with.
