Butter, Ergonomics and Recoil.


The grass is now green so the cows are ingesting a greater volume of nutrition which is reflected in the color of our butter. Living grass contains significantly more beta-carotene (offers antioxidant functions that limit damage to cells) and vitamins A and E when compared to a conventional corn fed dairy diet. Note the butter on the bottom is store bought and from European grass fed cows. I suspect it is paler from the cows being on winter pasture. Grass fed butter does not have trans fats and has a higher level of omega 3 fatty acid and conjugated linoleic acid (CLA), these are beneficial fats our bodies need. Omega 3 can lower cholesterol, reduce high blood pressure, reduce joint pains, wrinkles and other skin ailments in addition to improving memory. CLA is an antioxidant that may have cancer fighting properties.


Here is the source of our butter and a wonderful moment. In this bucolic setting a little brother is helping his older brother with his milking chore. (In reality what Calvin sees is a little hand occasionally jut in from the other side of the cow and attempt to grab and squeeze while he’s trying to milk – it’s driving him crazy and Calvin keeps demanding “stop Sammy!”)

Here is a pic that's not related to anything except to help ease the transition to a completely unrelated topic:


Now on to the other completely unrelated topic: ergonomics and controlling recoil.

Have you ever handled a FNH SCAR? I recently did and noticed it was uncommonly comfortable, it essentially “fit like a glove.” It was easy to bring up to my line of sight (I didn’t have to move my head down to find the sights) and I could also bring it closer to the center of my body. AKs and many ARs were never that comfortable, so what is the difference?

It’s mostly the stock and the line of sight. The bottom of the stock is low (#2), it is almost even with the bottom of the pistol grip and the line of sight is very high (#3).  The stock also allows for an excellent cheek weld.


Not so with a conventional AK (nor as good as with an AR). Notice how much lower the line of site on this AK is compared to #3, if it only had the conventional iron sites it would be even lower... and in addition the stock is terrible.

But this can be fixed. Replace the furniture with a lower and shorter collapsible stock (from Tapco) and raise the line of sight with a rail from Samson Manufacturing (the RSR1) and a Burris optic and dimensions including the line of sight begin to approximate a SCAR's (the optic is farther out but that does not change the way it feels). It is much easier to handle compared to its former configuration.

I think the SCAR's dimensions better fit your posture in a high stress situation, which is with your head up and shoulders squared towards whatever a threat might be. Bringing the rifle in close (thanks to the collapsible stock) and closer to the center of your body (thanks to the lower butt and higher line of sight) also helps to better manage recoil (in combination with leaning slightly forward and bringing your elbows together).
