Blanks won't cycle without a BFA and that data would be useless because the bolt carrier isn't cycling low pressure blanks. A better test would be to stick the barrel through an insulated wall... View Quote Low-pressure was a reference to the level needed to lock the bolt back being at it's absolute minimum. All of this is completely doable. Firing through an insulated wall, while a decent suggestion, would result in wave reflection and possibly skewing the results. |

Why would you gather data on something that nobody has any desire to do?
The simple test is to fire it on a bolt action with the same length barrel and compare the muzzle numbers and ear numbers. These are relevant. If you want the noise level of the action cycling, measuring the dB of releasing the BCG and chambering a round would be close enough for government work. |

Why would you gather data on something that nobody has any desire to do? You're already all setup, for testing, so how much more effort would it be to get the data? Very minimal! The simple test is to fire it on a bolt action with the same length barrel and compare the muzzle numbers and ear numbers. These are relevant. Yes, exactly why I suggested this in my previous post. If you want the noise level of the action cycling, measuring the dB of releasing the BCG and chambering a round would be close enough for government work. You know, for a fact, that a bolt unlocking, extracting a round, and a carrier moving rearward is quieter than one moving forward and locking a round into the chamber? How about factoring in the escaping gas used to extract the round and run the bolt back into battery? I think this is all pertinent information, especially when such dubious claims are in question.

So the directional blast of the BFA, and the comparatively low gas pressure escaping the bolt carrier vent ports and the chamber, along with the slower carrier velocity wouldn't skew the results? View Quote The whole point is to see the lowest metering of a BC during operation. So, no, the low pressure round wouldn't skew the test. If this meters around 120db "at the ear" (speculative for example purposes) and the Mfr claims a total signature of 118db, than there is very good reason to be suspicious. However, if the Mfr's silencer can get to near this number, you know their product is achieving near absolute attainable suppression levels. Reasonable deduction. ETA: That Kart is pretty sweet |

Since people seem to be doubting the meter numbers, how about running a back-to-back test with another well known commercially available suppressor during the same session to see what numbers you get and how it compares with the SAS?

Even so, it's almost irrelevant unless you step into subsonics, as the crack is louder to bystanders than the cycling of the action. View Quote All the time, I hear ppl claim their AR is so quiet that all you can hear is the action. Well, how loud is the action? If this test can quantify the carrier noise, we will have a baseline for these claims. We'll also know if ~119db at the right ear is a plausible feat. Running a can that has been 3rd party tested, and verified, is a good suggestion. It puts some faith in the metering equipment's accuracy. |

If it won't ever occur, that's probably a good hint as to why nobody tests for it. To be clear: You want the isolated sound of an AR-15 firing, but ONLY the port noise from that, not the overall noise. Right? Nobody tests for that because they test for how their silencer performs. What you want is irrelevant. |

If you can get someone to work-up some low-pressure blank rounds (just enough to lock a bolt carrier open), you'd be able to test absolute minimal db metering of a carrier cycling (at the shooter's ear).

Yes. This is the real question regarding action noise. View Quote The bumper at the rear of the buffer rebounds off of the rear of the buffer tube and imparts forward momentum to the carrier as soon as it starts forwards. The exception would be an over-damped hydraulic buffer or a rifle that has been leaned down so far on gas as to barely lock back and not impact the rear of the buffer tube. |

Here is a Vid from Craig Sawman Sawyer. He got to shoot a SAS can for the first time in Jan of 2017, and is now running them due to the reduced Blow back and great DB reduction.
Failed To Load Title More to follow, video wise. If any one is in the Northeast and wants to try the Claymore First hand Contact me and we can set a date to meet as well. I am in New London, NH. People are always wanting quieter, lighter better suppressors. When something comes along that is just that, They want to call it a fraud, or BS. Tim or my self are willing to let anyone shoot and test this suppressor. You can come to Reno, or New Hampshire. If your close enough for us to come to you we will do the same. Tim is going to continue to test and evaluate the Claymore, and provide the data. I have been in the class III business for 10yrs, a lot of suppressors have come and gone. New tech and new materials have changed the industry. To date this is the quietest 556 can i have every shot. Come try it. You will be impressed. Thanks RLTW Steve 816-718-9489 |
