Some of us; myself included enjoy target shooting with AR’s with the scope mounted above the carry handle.  This allows transition between the iron sights below and the scope mounted above.  The problem is the scope generally sits about 4 inches above the barrel which can, at times, make the elevation settings on the scope run out before the scope is on target.  My fix for this is as follows.

1 – To protect the scope where the rings will clamp down, wrap that portion of the scope in black, cloth hockey tape.

2 – Shim the back scope ring by folding up a small, thin piece of aluminum foil and securing it inside the back scope ring with electrical tape.

3 – Place the scope inside the rings and using allen wrench screws that are one size wider and longer than the existing scope ring screws, fasten them down in a criss cross pattern making sure the crosshairs of the scope remain properly aligned.

4 – Use a quick adjust cheek rest attachment on your stock which folded down allows the iron sights to be used and snapped up allows good cheek weld on the high mounted scope during transition.

Your scope is now mounted and the cloth around the scope allows the rings to bite down on it without movement.  The oversize screws when tightened reformat the original scope ring holes and allow for a firmer grip without having to use loctite, and the shim allows for a slight downward slant to the scope which will now give you enough elevation adjustment to hit the target center without running out of elevation adjustment options.

It is a good idea to choose what you are going to rely on from a weapons perspective post apocalypse for self defense, property defense and other types of mobile defense.  The following are my humble suggestions.

  • A semi automatic handgun in either 9mm or 45ACP
  • A 357 magnum revolver
  • An AR-15 
  • A 12 gauge pump action shotgun
  • A long range rifle either in .308 or 7mm Rem Mag 
  • A sturdy fixed blade knife

My choices have factored in my particular needs.  Obviously your needs in terms of caliber/gauge might be different.  Choose wisely.

So The SHTF and the ultimate survival scenario is thrust upon you.  When all is said and done you need to make sure that whatever rifle you consider your primary survival rifle is up to the task.  So ask yourself the following questions to see if your survival rifle is the best choice for your all around needs.

  • Is the rifle accurate enough?
  • Is ammo plentiful and do you have a good method to carry all that additional ammo?
  • Are spare parts available?
  • Do you have enough reliable mags and a good method to carry the mags?
  • Is the rifle durable enough?
  • Do any of the modifications you’ve made make it too fragile for heavy duty use?
  • Is the rifle easily transportable?
  • Can you use a carry strap or sling with the rifle?  They can get heavy when carrying for extended periods of time without one.
  • Is the rifle usable at night and in extreme weather conditions?

Remember having mutiple rifles and being proficient with them is fantastic; but you are basically only going to use and or carry one at a time so make your decisions wisely.

Here’s the method I use to zero the iron sights on an AR-15 rifle.  The purpose of zeroing your sights is so that your point of aim equals your point of impact.  So here’s the method I use on the AR-15.  Feel free to ask any questions if any of this needs clarification 🙂

  1. Set your elevation knob to 8/3 low or if you are using the carry handle which is what I do, to 6/3 low.  The elevation knob will be located just below the peep sight.
  2. Flip the aperture to the long range sight (small peephole) although as you get older you may find the short range aperture (large peephole marked 0-2) easier to use and if that is the case then use the short range sight.
  3. From a steady position aim at the center bulls eye of your paper target, which should be set out at 25 meters which is equal to approximately 27.34 yards and fire a 6 round grouping.
  4. If your grouping has hit the bulls eye then there is no further adjustments needed.
  5. If the grouping has not hit the bulls eye then calculate how far away you are from the bulls eye both vertically and horizontally and adjust as follows.
  6. Calculate your clicks of windage (left to right) required to move the impact point towards the center of the bulls eye.  On an AR-15 using .223 ammunition at 27.34 yards, each click equals 3/8 of an inch.  Then adjust by rotating the windage knob located on the right side of the carry handle.
  7. Calculate clicks of front sight elevation (up and down) required to move the impact point towards the center of the bulls eye.  On an AR-15 at the previous referenced distance; elevation equals 3/8 of an inch for each click.
  8. Using a $7.00 or so front sight adjustment tool (much easier to use then a nail) depress the front sight plunger and turn the required number of clicks to move your point of impact towards the bulls eye.  Clockwise lowers the sight but raises the point of impact.  Counter clock wise raises the sight but lowers the point of impact.
  9. Fire another 6 rounds at the bulls eye.  If your grouping hits the bulls eye your adjustments are done.  If not, repeat steps 5 through 9 until your point of aim finally equals your point of impact.

The following are my italicized responses to some common AR-15 Questions that I am frequently asked.

Q – Is the .223 Remington round and the .556 NATO round the same?

A – No.  While they might appear similar, the .223 Remington is loaded to lower pressures and velocities than the .556 NATO round.

Q – Can I shoot the .223 round out of a barrel stamped .556?

A – Yes.

Q – Can I shoot the .556 round out of a barrel stamped .223?

A – No.

Q – What’s the main difference between the A1, A2 and A3 receiver?

A – The A1 receiver has a carry handle with the rear sight built into the handle.  It requires a tool for adjusting and is adjustable for windage only.  The A2 receiver has a carry handle with the rear sight built into the handle.  It is finger adjustable in increments for windage and elevation.  The A3 receiver is a flat top receiver with no carry handle.  It has a Picatinny rail mounted on the top for attaching optics.

Q – What is twist rate?

A – Twist rate is how long it takes the bullet to make 1 full rotation in the barrel.  As an example a 1/9 is 1 full rotation for every 9 inches of barrel.

Q – What is the military version of the AR-15 rifle?

A – The M16 rifle.

Q – What are some of the advantages of an AR-15 rifle?

A – They are flexible, accurate, reliable, have a proven performance record and have parts that are readily available  

Q – What is the ideal barrel length for an AR-15 rifle?

A – 16 inches. 

Q – Why are iron sights important?

A – Iron sights are often the primary sighting system and offer the quickest method to acquire a target at short distances.

Q – What size magazine is best and how many magazines should one have?

A – The 30 round magazine is best and one should generally have a minimum of 10 magazines.  Check your local area laws regarding magazine capacity limitations as 30 round magazines are no longer allowed in some states.

Q – What’s better, plastic or railed handguards?

A – They are both good.  Plastic handguards are there to cover the barrel to prevent you from burning your hands.  If you’re a minimilist and do not want to add accessories plastic is the way to go.  Railed handguards also prevent you from burning your hands but have the added benefit of rails to allow the quick attachment of modular accessories such as flashlights and foregrips.  If you like adding accessories, then railed is the way to go.

Knowing the difference between cover and concealment when under attack is of vital importance.  Cover is anything that provides varying degrees of protection from gunfire.  Examples are brick walls, concrete walls, engine compartments of vehicles, logs, thick tree trunks, trenches, rock formations, a freezer full of frozen food items, hillsides, metal dumpsters, sandbags at least 12 inches thick, 55 gallon drums filled with sand, steel doors, concrete parking barriers and telephone poles as examples.  If it can generally stop a bullet it is considered cover.

Concealment provides a place to hide but will not stop gunfire.  Examples are walls of a normal wood frame house, small trees, foliage, darkness, bushes, tall grass, shadows, car bodies, behind non steel doors, tables and couches.  If it cannot stop a bullet it is considered concealment.  Make sure you know the difference; it just might save your life someday.

It’s also important to know the penetrating depths of various calibers at various distances.  Things that might provide protection against a 22LR, 9mm, 45ACP, .223, 5.56 NATO, or a 7.62×39 may provide less protection or at times no protection against a .308, 30-06, 7mm Rem Magnum, 338, 300 Winchester, or 7.62x54r for example.  And if it’s a 50BMG; well pretty much nothing is going to stop that round.   Know your weapons, know your rounds, know the penetration depths at key distances and your odds of survival increase dramatically if the SHTF.
