It's cool, but there are definitely better things, and they also reflect the value, so they are exactly what they are worth.

I was pleasantly surprised by the excellent damping, which is, however, more effective for larger calibers of 5.5 and 6.35 mm due to the 8.5 mm partitions.

  • Excellent processing.
  • Good attenuation.
  • Great price.
  • It's a pity that the partitions are made of plastic and not aluminum, even at a higher price.

Great workmanship at a very good price.
Dampens well, excellent to disassemble and clean.
Except the baffles could have been aluminum and not plastic.

  • Works, dampens really well, my guess : 80% of the wound after the shot disappeared but I'm not a pro just by ear I can only recommend.
