Oceania Defense 5.56 Ratchet Lock GEN 4 Single Flow Incoerl Suppressor Black

Oceania Defense 5.56 Ratchet Lock GEN 4 Single Flow Inconel Suppressor Black. SPECIAL REDUCED PRICE. These were made for a Military Contract and are excess stock.

NOTE: THIS DOES NOT COME WITH A Q R MUZZLE DEVICE IT CAN BE ORDERED SEPARATELY.

The 762 Ratchet Lock Titanium Suppressor uses the latest flow technology for the best sound reduction in the least size.  Designed for 300 BLK in both sub and supersonic as well as 308 / 762x51.  The can will also perform well on 762x39, 6.5 Creedmoor, 6.5 Grendel, 6.8 SPC and 5.56.  The 762 RL attaches to a 90 tooth muzzle device (Not Included) using  two ratchets to provide 4 degree of rotational alignemnt.  This suppressor is designed for moderate rates of fire.

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 which prevents the can from unscrewing.  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.

This can is designed for jacketed bullets only.

Average multiple in house results of sound testing using BK2209 with BK4136 at 1 Meter left of muzzle and 1.6 meter high:

• 12" AR 300 BLK Barrel using 110 grain supersonic at 2240 FPS no suppressor:  168
• 20" Rem 700 Barrel using 147 grain SA at 2597 FPS:  139
•  20" Rem 700 Barrel using 147 grain SA at 2584 FPS no suppressor:  168
• 14.5" AR 15 using M193 55 grain at 2887 FPS: 138
• 14.5" AR 15 using M193 55 grain  at 2846 FPS no suppressor: 167

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.

These are designed for semi auto use on any 762x51, 762x39 and 300 BLK supersonic or  FA on 300 BLK subsonic.

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 and full auto.  Designed for 5.56x45 it will aso work with any 22 cal bullet (or smaller) including 22-250.  The 556 RL attaches to a 91 tooth muzzle device (Not Included) using  two ratchets to provide 180 tooth indents or 2 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.

The can will perform much better on semiauto rifles with an adjustable gas block or piston to reduce noise at the ejection port.

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 full auto on any 556x45.
