556 Suppressor

Product Description

The 556 - 20 Samson is the latest cross flow design which takes the place of the original Samson as well as replaces the larger diameter 556-45. The Samson is designed to operate with moderate rate of fire on barrels  down to 12.5".

Preliminary in house SPL testing:

14.5" NEA AR15 using 55 grain M193 at 2991 FPS:
5 shots at muzzle with no suppressor and 4136 mic at 1.6 high over grass and 1m left of muzzle - 166.1
10 shots at muzzle with new ODL 556-20 Samson and 4136 mic at 1.6 high over grass and 1m left of muzzle - 134
10 shots at ear with new ODL 556-20 Samson and 4136 mic about 50mm right of my ear - 136


This can is built from Ti6Al4V Grade 5 which is 90%Titanium, 6% aluminium and 4% Vanadium using a selective laser melting process. This process provides a completely monolithic structure for added strength with minimal weight. The suppressor is then stress relieved, heat treated and nitrided to provide a yield strength of around 1000 MPA and 1200 UTS. The internal structures have a 65 Rock C surface hardness due to the nitriding which drops back to 39 over the next 28 microns which increases the baffle longivity.


Currently not available for sale in the USA.
