Is something on this page wrong?
Mount interface: OPS/AE A-Mount. Nothing in the catalog attaches to it yet; check with the manufacturer for the hardware it takes.
The Thunder Beast Silencer Summit fires every suppressor entered on the same gun, with the same equipment. AEM5K was measured in 3 tests. Figures can only be compared with others from the same test, so each one links to everything else fired on that gun.

Manufacturer claim
- The AEM5K is a blend between the AEM5 and the AEM3: it pairs an A-length mount with the shorter AEM3 baffles, offering a simple swap from a longer A-length can using the same hardware while being only slightly longer than an AEM3. The difference in sound and flash performance from the AEM3 is described as negligible.
Is one of these wrong, or does our wording say something the source doesn't?
