Based entirey upon differing skill-sets, you may very well be able to wring 2 MOA out of the stock, mil-spec Trigger, whereas I cannot. But just because I cannot manage to shoot a mil-spec Trigger well, does that mean the rifle's accuracy ought to be condemned? THAT is the uncertainty and variability of results that adopting an easier to use aftermarket Trigger helps to eliminate.
Is it an SAI R18 k2 with a TriggerTech installed for accuracy testing? Yes, as I have clearly and repeatedly stated. It is also an SAI with a Leupold Mk5 optic installed that the rifle does not ship stock with. It is also an SAI with a B5 SOPMOD Buttstock installed, which I personally prefer over the stock Magpul MOE. The R18 Mk2 also does not ship with Back-up Iron Sights, nor does the factory package include a Magpul Vertical Forward Grip and MLOK Sling Attachment Point. But I installed those additional accessories on the test rifle for my personal convenience. Does the presence of any of the above "add-ons" fundamentally compromise or alter the results of my user review? You evidently think that they do. My opinion differs. My review however, so my methods and rules.
