556 Ratchet Lock Inconel Suppressor

Product Description

The 556 Ratchet Lock Inconel Suppressor uses the latest flow technology for the best sound reduction in the least size.  Identical in design to the Titaniuim suppressor, the inconel is heavier but will support extreme fireing schedules.  Designed for 5.56x45 it will aso work with any 22 cal bullet (or smaller) including 22-250.  The 556 RL attaches to a 90 tooth muzzle device (Not Included) using  two ratchets to provide 4 degree of rotational alignemnt.

The suppressor mounts in about 3 seconds with 2 full turns of a ACME thread.  As the thread starts to tighten against the conical seal, the rotation rings clicks into place like a torque wrench which prevents the can from unscrewing and provides a consistent install tension.  To remove, twist the rotation ring until it clicks which unlocks the ratchet and keep turning to unscrew the suppressor. The best feature about the lock ring is that the motion to install and remove is intuitve and effortless.  It also prevents ratchet clicking noises when installing since the ring keeps the ratchet disengaged from the teeth during normal operation.  If you want to hear the teeth, just put the ring in the locked position before installing.



Average multiple in house results of sound testing using BK2209 with BK4136 :

14.5" AR 15 using M193 55 grain at 2905 FPS: 134.88

14.5" AR 15 using M193 55 grain at shooters right ear: 138.68

14.5" AR 15 using M193 55 grain at 2905 FPS:  A weighted

14.5" AR 15 using M193 55 grain unsuppressed: 166.58


Prior to release this can was extensively tested for both sound and durability including: high firing rate followed by water dunking and shooting, drop tested onto concrete suppressor first with the weight of a rifle followed by firing, and many others.  Built for the most extreme use but easy to remove even after extended firing strings.  QD mechanism provides a robust atachment and consistent POA POI shift.


This can is built from Inconel 718 using a selective laser melting process.  This process provides a completely monolithic structure for added strength with minimal weight.  The suppressor provides a yield strength of around 640 MPA with over 20 % elongation. Inconel retains most of its yield strength well into the 700C degree range which make it the ideal material for extreme duty.


These are designed for any 556x45.
