Updating a battle rifle with optics

I have on numerous occasions watched people try and turn their AR15 rifles into sniper rifles and long range shooting rifles.   The AR15 has become so modified that it’s really hard to say what it’s limitations are because their are many things that it can do if modified.    I remember when the M1A ruled competitions, but now it’s really hard to find them anymore.   There have been many long range shooting modifications that have made the AR15 a 1000yd rifle.  One thing the AR15 is really known for doing well is being accurate.  I jumped on that bandwagon a few years ago and enjoy the ones that I have.  One thing that the AR15 in .223 is also known for is lack of penetration on hard targets.   With the invasion of Iraq, there have been numerous stories of guys not  being able to shoot through concrete walls to get a BG that was just about a foot on the other side.   The AR15 with M855 or SS109 can penetrate steel at reasonable ranges, but when it comes to taking 300yd shots at hard walls, it is out of gas.

Considering what the M855 round can do as far as penetration, it’s no weakling when it comes to punching through targets, but that energy gets to be useless on anything other than flak jacket type armor.    The M1A or the .308 for that matter is an over kill at close ranges under 200yds and it’s going to do much more than what an AR15 or M16 can do, but when  you get out to 300yds + good rifles scopes, accurate rifles and a .308 are going to hit targets harder, punch through targets harder and save the guys carrying the M4 rifles a lot of ammo and get the job done.    Mounting optics and finding really good and fast bullet compensator on the glass shouldn’t slow you down and will help you get fast target acquisition at medium ranges.

Optics that hold zero

There are a great many  things that I have learned over the years about what is a combat worthy firearm and what is a hobby type of firearm.   I have seen such huge variations in AR 15 rifles that I really can’t say that some manufacturers of direct impingement firearms are less reliable that gas piston guns.   There are some variations in the older design that have machine their parts so well that they really do run on less lubrication and have run in some tests off thousands and thousands of rounds with out failure.   I will say that gas piston guns will run cleaner, but are they more reliable than a high end AR15?   I don’t think most of us will really ever know the answer to that because there are always variables in how a firearm is maintained and in what climate and conditions it is subjected to.

If I had to issue handguns and rifles to relatives, I’d probable go with a gun that is easy to clean and easy to shoot, if I want a gun for myself, I’ll take the guns that work the best for me.   I know I put more effort into making sure every rifle I own has the right parts staked and loctited down.   I have broken a few Tasco and Simmons optics, but I have never had Leupold rifle scopes, Zeiss or Trijicon optic fail on me.   There are faulty mounts and scope rings out there, but even the less expensive ones will work if you use Loctite on them and don’t over torque them.   Over torque screws on firearms can mean broken screws and I have learned that the hard way with a DSArms SA58.   The FAL is not a very good gun for using optics, but it can work if you lock everything into place.  Cleaning the guns with this scope mounts is difficult, but the FAL can be made into a good DMR gun.

My Ranch gun and configuration

If you learn how to match your ammo to the barrel twist and do some serious slow fire testing you should be able to get MOA with a 3 shot group from one of these guns.   I use the Weaver Grand Slam on another Mini 14 if I think I might have to deal with prairie dogs.   If I am going specifically to hunt these animals, I’ll take a 22-250 and plan to setup for an afternoon with a packed lunch.   I’m a big believer in having a good a pair of binoculars with me just for getting a better field of view.

 

Even though I own more  than a few combat worth AR 15 rifles,  I still got back to my trusty Ruger Mini 14 for the job it was intended to be used for.  As I was discussin previously when it came to what types of footwear to use throughout the year, It would be nice if we could take a light version of what many of us carry when we know we don’t need the standard setup.   The great thing about the Mini 14 Ranch guns is that they are light and short, and they are also already setup for optics.   I have a few of these  guns with different Weaver rifles scopes, but I think the most applicable would be a fixed power 28-30mm optic.
