Hey guys,
Just got back from a range trip and I noticed something for the first time with my new Octane 45 can: After firing 1-2 rounds, I can grab the can with a gloved hand and and twist it. The weird part is that the suppressor piston isn't tightening on the barrel threads, it looks like the piston is rotating within the suppressor. Once the piston rotates a couple degrees, it seems like the piston pops back into the teeth inside the can and I can no longer rotate it. Is this expected behavior? I've only taken it out three times and haven't noticed it before; I just don't want to risk a baffle strike. Thanks in advance! |
| My only thought why would be that you are 'limp wristing' the shots and the gun is rotating (due to rifling) when the piston is engaged. I would have guessed it was a rotating-barrel pistol, though. The movement should be roughly linear. It takes some bit of energy to get the can to rotate in the split second that it is disengaged from the teeth. |

Same issue with my Octane 9. It looks like the booster housing lacks appropriate-length guide rails (for lack of a better term) to keep the piston from rotating during firing. For me, this results in the piston failing to completely return to battery after 5-10 shots due to a couple degrees of rotation, with the piston teeth coming to rest on the ridges between the shallow scallops cut out for the piston teeth at the end of the piston housing. This is the one bone I have to pick with an otherwise excellently designed suppressor.
SilencerCo could fix the issue by a small change in the way they've designed the booster housing. I'd be interested to get their take on this issue. |

I wonder if putting a stronger recoil spring in the gun might help. I don't think so, but it's always possible. The piston gets part of its boost from pressure in the can, the other part from the physical movement of the piston rearward we call recoil. The two happen at the same time so the gun THINKS it doesn't have the full weight of the can on the muzzle. IT's only in unlocking that it takes more energy to tilt the can in a Browning tilting barrel action. A stronger recoil spring will keep the teeth on the piston engaged longer. I watch high-speed video of otherwise strong folks shooting pistols and I can always see the rotation of the gun in their hand. Other troubleshooting possibilities: 1) Replace and lube the "O" ring so that it operates properly. 2) Check to ensure that you have proper tension on the piston and have screwed the piston retainer all the way down. 3) Check that the pistons are all aligned properly and seated fully with front cap tight. 4) Try lighter and heavier loads. 5) Let a weight lifter shoot it with a death-grip and see if he can duplicate the malfunction. (that will isolate the operator error) 6) Try same can on different host (friends) to see if you can duplicate. 7) Try intentionally holding it lighter so that you can feel gun rotate in hand to try to duplicate |
