I have been what some term a "Survivalist" all my life. I say I am a "Perpetual Boy Scout". Some inner voice has told me all my life that the simple skills are the most important in life. Example: As a very young kid I INTENTIONALLY experimented with the best, and surest way to get a small fire going. I discovered in my early years between the ages of 11 and 13 that to dig a hole, and build a fire, it left no trace of my being there.
I learned that you could cut up some veggies, a little meat (squirrel? rabbit?), and put them in an old half pound coffee can, replace the lid, and put it in the bottom of that hole, shovel the coals back in on top of it, and an inch of dirt over that, and come back hours later to a hot meal. When finished, just throw the can back in the hole, and cover it up.
The Scouts taught me many things, and a very wise, old grandmother taught me other things.
But this thread is about a small idea about your rifle, and in this case the M4.
In the pictures you will see my M4, with a scope, with a back up sight just below and behind the scope, and about 10 inches of bicycle inner tube on the sling. The scope and backup sight are self explanatory but, the inner tube? It prevents the sling from slipping off the shoulder. It can be removed, and with one end pinched one can carry small amounts of water, or drink from it. It can be cut into small rubber bands, and if one has a wound on the arm area it can be cut into the appropriate width and worked up the arm to form a tourniquet or even a covering.
Next to pistol grip, note the G.I. can opener, and magnesium fire starter. The can opener can be used as "a can opener", a knife, or a straight bill screwdriver, such as needing to take the scope off if damaged, and it will UNZIPP the hide on just about any size game one might kill, or gut a fish. The magnesium fire starter of course can be used with or without the aid of shavings off the magnesium. Also the can opener and fire starter can be used together, if needed.
Both are held INSIDE the pistol grip, with an inner tube cap, and different size rubber bands made of the same inner tube. All useful in a survival situation. The fire starter was cut off at an angle on one end so that it would fit flush inside the handle.There is also room for small fish hooks, and weights, and line dropped in loosely.
Some may have already thought of this, and some maybe not. Hope it helps.
