Griffin Checkmate-HD
The Griffin Checkmate-HD is a rimfire suppressor rated to 5.7x28mm, built from stainless steel and mounting by quick detach on the EZ-LOK system. It measures 5.04 inches long and 1.07 inches in diameter, weighing 5.8 oz. As published, it is user serviceable, but not full auto rated or modular, and it is made in the USA. Griffin notes a 32.15 dB figure for it, one of only 88 entries here with a published number, and dB ratings are manufacturer-reported and not directly comparable across brands. Measured against the 14 5.7x28mm-rated suppressors in the index, it lands on the heavier side for weight (5.8 oz), in the shortest quarter for length (5.04 in), and about in the middle for price ($435). The closest listed comparison is Thunder Beast 22 Take Down, another 5.7x28mm-rated can, priced at $425.
