Ek stem saam dat die artikel meer inligting moes bevat het maar daar was 'n paar probleme. Ons moes spesiaal plek maak vir die artikel in die tydskrif want die betrokke uitgawe was reeds ten volle beplan. Ek het nie tyd gehad om self die skryfwerk te kan doen van 'n meer in diepte artikel nie en die inligting wat ons ontvang het van die toetsers was baie skraps. Ek moes ook meer as een keer daarvoor vra en het dit later ontvang as waarvoor ons gevra het. My aanname was dat een van die toetsers die hele proses sou verduidelik en vir ons al daardie inligting veskaf, dit het toe nie so gebeur nie. Die tydskrif was nie betrokke by die toetse self nie, ons het bloot bygestaan saam met die vervaardigers en gekyk dat alle produkte sover moontlik op eenderse manier hanteer is tydens die toetse. Daar is op faceboek genoem dat ons die resultate sou plaas en om nog 'n maand te wag om 'n meer in diepote artikel te doen sou te veel mense ongeduldig gemaak het. Ons is alreeds die dag na die toetse gepla oor wanneer die uitslae sal verskyn.
As ek ooit weer so iets publiseer sal dit op 'n ander manier gedoen word. Terloops, ek het oor die jare al verskeie knaldempers getoets en bygestaan toe baie ander geskiet is en ek moet se, my ondervinding is dat jy nie eintlik knaldempers kry (van die waarna ek al geluister het nie) wat vreeslik "sag" is nie. Die klank word wel gedemp maar as jy na so 'n paar skote geluister het sonder oorbeskermers begin die knal jou (of vir my) te pla.
Bogenoemde klink na 'n klomp verskonings maar dis hoe dinge gebeur het. Jammer die uitslae het nie aan jou vereistes voldoen nie.
Mooi loop
Baie dankie vir die terugvoer Koos, ek voel jou pyn en jy het my simpatie
Ek dink die inligting is waardevol maar die wetenskaplike in my wil dit kan kwantifiseer en in n raamwerk plaas wat ek verstaan
Groot klomp werk wat julle gedoen het en baie interesant.
Wat bedoel julle in die artikel met "recoil amount" bv sus tac 45.1% en OVS silencers 5.2%.
Indien ek n silincers wou koop, uit en uit vir die een wat die meeste recoil wegvat, watter een van die 2 sal dit dan wees?
Sustac vat die meeste recoil weg. Klank en terugskop kolomme is van beste na swakste ge-orden. let ook daarop dat resultate gepubliseer is soos dit ontvang is.
I was struggling to read / interpret the results so created my own table (attached) to try and make sense of the test.
I gave each element of the test a weighting (in yellow at the top) to try and come to some sort of overall result / ranking.
Its difficult to come to any firm conclusions without knowing the retail price and whether the silencer is a reflex or not (which is why I only gave the length a weighting of 5%). Also - its impossible to assess build quality and estimated durability from the test results but I hope this helps somehwat in making a decision re: which silencer might be better for you.
Cheers

Baie dankie en interessant. Ek sou net recoil 'n hoër rating as klank gee. Hoe meer recoil 'n silencer weg vat hoe beter. My opinie.
I thought the test was great and many thanks to all the contributors! My following comments are not criticism but genuine questions to provoke some thoughts and hopefully some feedback and guidance by the men in the know!
A couple of observations and questions:
1. The mass of the silencers did not correlate with the reduction in recoil. Or putting it differently, in this specific test, Newton's Laws apparently only accounted for a small proportion of the recoil reduction. Can we conclude that the lighter silencers that had a large amount of recoil reduction did so because of their design (retarding gas flow to generate an opposite force to the recoil direction)?
2. It would have been very interesting to have measured the MV of all the shots and compared with the MV of the unsilenced shots. This info would give us more discussion material about silencers increasing (or not) MV, and which silencers do it better.
3. I am curious as to how the rifle was fired (trigger activated) for each shot? In Sus-tac's videos on their website, the trigger is pulled by a person using a wire hook (I assume to supposedly remove the human component in pulling the trigger?) and some of the trigger pulls appear visually to be harder yanks than others - whatever the reality, this method does not remove the human variable completely. Can we be sure during this test that the same force was applied on each trigger pull? Obviously not all triggers break at the same level of force, so there may be a contributing variable there too.
4. Were all the silencers brand-new and unfired at the start of the test? If not, what effect does 'wear and tear' have on silencer performance (eroded baffles, carbon build-up etc)? Does a new silencer of the same design perform better or worse than a 'broken-in' one? Comparing a new silencer of one design with a used one of a different design throws in a whole new bunch of variables...

Sal ook grrag wil hoor. Baie dankie vir die mense se harde werk om al die inligting te versamel en dan op so mooi manier vir ons weer te gee. As ek mag voorstel maak, kan ons nie komme bysit met inligting soos bv. materiaal gebruik,prys,diensbaar(lees, kan uitmekaar haal), dit is alles dinge wat jou keuse sterk kan beinvloed.
As jy sien hoe silencer kan toe carbon omdat ek hom nie kan uitmekaar haal en mooi skoon maak, is die een wat dalk bietjie duurder is maar kan oopmaak dalk 'n beter keuse omdat sy leeftyd baie langer gaan wees.
Nico Harris wrote:Om silencers uit mekaar te haal om skoon te maak werk nie. N silencer is soos n loop. Dis n “consumable”.
Dit is waar en ek moet seker maar gewoond raak aan die idee, dit voel nog steeds net vir my of my lope langer hou as ek hulle so nou en dan kan skoonmaak.
Die laaste tyd te veel manne gesien wat silencers uitmekaar skiet waar die carbon in die pad gekom het.
