Hunting overkills this Fall

For most of the Northeast, hunting will start in about 6 weeks for archery and then small game begins.   Archery has gained a  lot of ground in this region because so much of the good hunting areas are populated and it’s hard to safely manage deer populations if areas where it’s not really safe to use a firearm.   I still don’t know why so many people go with monsterous optics that when put under any kind of realistic hunting test, will always slow you down.   Whenever I ask people what they are doing with a 50mm objective on a gun that is really meant for something that weights 800lbs and they are out hunting white tail, they usually say they are afraid of making bad shots.

From my own personal experience in the military and law enforcement community, I think hunting with a red dot is probable more practical than any optic that magnifies more than 5xs.   For small game I’d recommend against using a red dot, but there have been times I’ve been tempted to just bring a Mini 14 with an Eotech out for while tails just because the speed I get with that configuration is better than any lever action or 7mm bolt action.   Whenever you are thinking about doing long range shooting, go ahead with magnification, but wheneve you are thinking about rifle scopes for hunting applications, do a realistic gauge of how good your eyes are and what kind of opportunities you may expect when out in the field, and don’t slow yourself down with too much magnification or an optic that has an eye relief inhibits your mobility.

When optics go down

rifle scopesThe Trijicon NSN has iron sights mounted on the top of the rifle scope which can come in handy in closer situations and are a less expensive alternative to mounted a red dot on your ACOG.    That is worth the money if you are in the line of work that calls for it, but for general blasting and plinky, I think that $1800 optics is a bit much.   The Eotech 512 is probable my recommended optic for an M4.  I think people can get carried away with optics on the M4 because even though the rifle is pretty accurate, it really is not very powerful or effective past 200yds.    With a growing selection of combat optics you can put on the AR15 type rifles, one other suggestion I have for shooters is to always keep your iron sights on the rifle.   I’ve seen a few people show up at classes with just an Eotech mounted and they complained the front sight blocked their FOV.   Well,  taking a 200yd shot with an Eotech that has a dead battery is like parking a mini van from the furthest back seat.

There are numerous reasons that your rock solid rifle optics will go down.   Some optics use batteries which will always go down at some point.   Your tough Trijicon ACOG will hold zero under most combat conditions, but a 30 caliber bullet can still dismount it.     Reticles can come loose, rings can fail, glass can break and numerous other things occur in a fight that don’t normally happen with occassional hunting trips.   Most rifle optics won’t handle real big drops, but having the ability to have a backup just incase the glass goes down.  Co-witnessing your sights is a simple answer for those using rifle scopes and quick detach mounts in my opinion are worth considering.   It has never happened to me in a hostile situation, but having a MOA rifle with broken glass that is solidly mounted on my rifle has got to be a nightmare sceneario.

Magnification for the Eotech

rifle scopesLike many tactical shooting accessories, you have to put a lot of thought into which type of configuration you want on your Carbine before you spend the money or you will find out real fast  you just spent $500 on some thing that you really didn’t need.    The differences between using some of the fixed power Trijicon rifle scopes, Leupold CQT, and the Eotech 512 are considerable.   Each can be used for many things with an advanced shooter, but they are intended for certain applications and within those boundaries, they work well.    There was a shift away from the Trijicon ACOG for some military and law enforcement personel because once we invaded Iraq, and the house to house fighting went on for several years, the need for magnification was virtually unnecessary.

The Aimpoint and Eotech optics are hands down the most popular CQC optics being purchased or issued, but there are times when just a little bit of magnification would be helpful.  If you are using rifle scopes 100-200yds away from a potential target, being able to see what they are holding in their hands or see there faces is a big help.   If you determine that they are a threat, then depress the trigger and get the job done.   The Eotech magnifier is probable the most expensive magnification option, but it does the job if you think you may want the magnification.   Once you factor in the cost of the Eotech and the magnification optic, you will have basically spent the same money as Trijicon ACOG rifle scopes, but there are still differences in what you can effective use each for.   Think before buying and borrow your buddies rifles at the range before you spend the cash, if you do, you’ll get your moneys worth.

range estimations and value estimations

rifle scopesI remember the days when I would stare at rifle scopes and ask shooters how much they cost, and when they told me how the rifle scopes cost, I’d calculate that whichever rifle I was thinking about putting the scope on, the cost of the rifle was less than the cost of the optic.   I have no idea how much money companies are making off of some optics, but there is a certain point that I really don’t care how good people think  they are, 90% of people spending that kind of money on optics probable could get the job done with something that cost 50%-75% less.   In all of my years of target shooting and plinking, I have only had scope mount issues and 2 rifle scopes that ever broke.   Every rifle scope  that broke cost less than $100.   I have a few Leupolds that have been on bolt actions and semi-autos and they all hold zero and have excellent clarity.

If you do research on rifle scope manufacturers and there warranties, then put some thought into what kind of objective lense you think  you want and get the reticle that applies to your shooting purposes.  There are a lot of really interesting reticles being sold by various manufacturers and they work very well.   Mil-Dot reticles still have their place, but some of the range estimation reticles for varmint and big game work very fast.   Once you’ve determined which rifle scopes you want then get the best rifle mounts you can afford to get and remember to use loctite on every screw.   I have had scope mounts fail on me, but never when I used loctite.  For hard use optics I strongly recommend marking the heads of the screws so you can do visual checks to see if they are turning.

M4 Configurations and reticles

rifle scopesIt seems that the M4 AR15 variant is hands down the most popular carbine in existance in the United States.   There are plenty of AK and European military style rifles out there, but the accessorized M4 is king.    When I first stepped into the high speed tactical carbine school, I was going there from previously owning only Kalashnikov variant rifles.   The biggest promotion I heard from all of those owning an AR15 was how accurate they were.   It is true that the M4 and AR15 family of rifles ARE the most accurate combat rifles, but that doesn’t make them the most effective.   Ever since the Iraq invasion, the notion of just sending in a group of guys with M4 Carbines or M16s without a 7.62 DMR is not common.   There was a lot of hype about the military digging up M14s and giving them this role, but now that several years have passed, the military has been working with newer models of 7.62 rifles to eventually fill that role.
Along with the return of pistol driven guns, the 5.56 is being put in its place and other caliber rifles are being deployed.  The 5.56 and 50 Caliber rifles are doing their jobs quite well, but is some environments the 50 caliber is an over kill and something in between 7.62 and 50 Cal was needed.   The 338 Lapua seems to be filling that role very well.   The combat optic has also been evolving due to the fact that engaging enemies from 100-600yds is not very common and many of these rifle scopes are too much magnification for close quarters combat.    Eotech has a mangnification scope that allows you to go from 3x to zero magnification with the slip of a switch.    Trijicon ACOGs are hands down the #1 combat rifle optic, but red dots and various color and configurations of reticles are being used.   Each has it’s given purpose and it’s up to the operator to determine which application is best for them.

backup options for combat optics

rifle scopesIt’s always up to the operator to determine which configuration works best for him, but with the reliance on battery operatored optics and high mounted optics, it’s really a good idea for a user to consider the what ifs.   What do you do with your Eotech if the batteries die?   What happens if the optics come loose ?   Scope mounts can come loose and even break,  I’ve seen this happen on M1A rifles, AK, FAL and AR15s on several ocassions.   Sometimes its a good idea to train  yourself to be able to  hit a target without even a rear sight.   There have been several times where I actually forgot to flip up my rear sights on my co-witness configuration and just used the sight picture from my Eotech optic and the front sight post.   I never missed what I was aiming at and it was actually good practice for me.

If you can get a good cheek weld, and you know approx. where your poi is, you should be able to hit a man size target out several hundred yards with just a front sight post.   I’m sure you’ll burn through a few more rounds to hit your target, but it is possible.    Many Trijicon ACOG rifle scopes are being used with red dots mounted on the top or have iron sights mounted on the top of the scope.   The TA01 NSN seems to be the popular configuration I am seeing around.  This will give you fast transition from CQB or long range engagements,   It also gives you more than one targeting system incase one goes down.

Military rifles and hunting optics

rifle scopesAnother issue you may run into when using hunting style optics on a military style rifle is this.   What are you going to do if the optic fails or breaks?   Are you going to need to u se a screw driver to remove it or can you detach it quickly?   Quick detach optics and accessories can become very important if you have a failure of some sort.   For instance, I’ve seen plenty of incidences where soldiers in Iraq took bullets in their optics but the rifles still worked.   Always have backup irons on an M4 is a good idea.  Not only can batteries on something like a Eotech gun sight go down, but sometimes that can actually get broken from being slammed around or from fragmentation.   The Mini 14 ranch rifle is a very manueverable Carbine.   Even though the Eotech optic is primarily for military purposes, I’ve found the Eotech to work very well on a Mini 14 Ranch rifle.    The MOA dot works well with a gun that can shoot MOA as long as the rifle barrel has not heated up, which normally occurs after the 3rd shot, but from a hunting standpoint, I rarely know anyone that takes 3 shots on any hunting trip.

It is true that there is very little difference in application between a military optic and a hunting optic.   The really difference should really be in durability.   There are plenty of good quality hunting optics that will hold up to being dropped every once in awhile, but it has an awful lot to do with the mounts that are on the scope.   Many military rifle scopes attach to the rail of an A3 mount and there is very little to do other than adjust windage and elevation.   It took me a long time to be able to mount cylinder rifle scope properly because you’ll find out really fast if your scope in incorrectly mounted when making elevation or windage adjustments at long distances.   The first sign of an improperly mounted rifle scope is noticing that your point of impact is changing on a diagonal line.   The trick I learned was to make sure you are on a flat surface in the first place and then set your horizontal reticle lines to match a flat object in your home.   I’ve setup optics on firing lines and found out that even though the target looked like it was level with me, the table I was shooting from was actually slanted.

Top tier rifle optics

Zeiss rifle scopesThere is a point where people have to learn to realize that there are a great many firearms manufacturers out there that are making suberb firearms.    I’ve heard people claim that a certain firearm was superior in reliability over another.   Well, that is true to some degree, but I’d have to say there are some firearms that are in the top tier category and the durability and reliablity differences may vary in extreme circumstances.   Take a Glock 17 and put it up against a Sig 226 and you’ll see what I mean.   I’m sure the Glock will reguire less lubrication, but there won’t be much difference in 98% of circumstances.

Those of us old enough to remember when people told us that putting Glass on a battle rifle was not a good idea because they were brutal to optics and most scopes wouldn’t hold up are now old news.   Rifle scope have come a long way just as firearms have.   I’ve seen optics come back from Iraq that had bullet holes in them and they were still sighted in.   The differences between Leupold rifle scopes, Zeiss rifle scopes and Trijicon rifles scopes tends to really be about preference.    They all have moderate to expensively priced optics and the glass on them is superior to anything that was out 20yrs ago.   With a good pair of scope rings, these optics will work reliable in just about any hunting or military application.   I’ve seen all of the above mention optics on M14 rifles in Iraq.

Magnification from 0-20x

Trijicon ACOGOne problem that any hunter already knew was using too much magnification meant slow target acquisition, especially at close ranges.   Field of view is even more important in combat than in hunting.   In Combat you may be looking at a bad guys face with your reticle right on him, but 6ft to his right is a guy with his sights right on you that you can’t see.  I’d have to say that I belive that 3x-4x is probable the best of both worlds.   Trijicon knew that even an optic with zero magnification like the Eotech had an edge in some situations so now they have Trijicon ECOS which has a red dot optic which sits on top of the scope.  This will eliminate the problem of magnification in close quarters situations.

As The United States has been engaged in military operations since Sept 11th, there have been major changes in gear and combat optic for the Infantryman.   Most M16 rifles had iron sights on them, but now the vast majority of rifles being used are using some kind of Trijicon ACOGs  on them.   I still see the occassional hunting scope from Leupold and Designated Marksmen are common in every team.   The Eotech is still an extremely popular close quarters combat fighting optic due to its zero magnification and easy to track gun sight, but there are drawbacks, namely the battery operation.   Magnification has helped our men and women identify targets, wires, explosives ect. from safe distances and give the ability to put fast followup shots by using bullet calibration on their Trijicon ACOGs.

Mounts and durability

Scope MountsAdding the extra security may mean that your scope won’t come loose after a few thousand rounds.  I’ve seen guys with battle rifles with $1000 optics on them and after a few thousand rounds, the mounts came loose.  None of these individuals were using loctite.   Over torquing screws is something to be concerned about because screwing a mount in as tight as you possible can does not mean more security, it actually means more stress.   Loctite doesn’t add stress to your gun mount it just helps keep the grip on your screws so they don’t rotate after long firing periods.

There is much debate about which scope mounts are the most durable.   Some scope mounts are stronger than other just based on the quality of the metal, but the reality is that all scew on mounts can come loose over time.   One of the secrets that experienced shooters need to pass on is the use of loctite.   If you are going to be using a scope for serious shooting or putting an accessory in a firearm, you should seriously consider using loctite.
