Have enough guns? How about more upper receivers for your AR15?

I don’t think you even need to worry changing calibers if you want something different than a 556 upper.   I’ve seen guys turn an M4 Carbine into a varmint rifle with a snap of two pins on a lower receiver.  The real thing to look out for is changes in calibers, namely to a 5.45×39 upper.   Many times I’ve seen guys skip the hammer spring change and end up with a light strike issue with Russian ammunition. We sold a ton of the Smith & Wesson 5.45×39 uppers a few years ago but for some reason they just don’t seem to be available.

 

The LWRC M6Ak was a one off novelty deal which died a quick death and no word if it’ll ever happen again.
Right  now the biggest selling upper receiver we have are the Adams 5.45×9 uppers.  I had a customer take apart his gun side by side to my AR15 complete upper receivers and compare the piston differences.  There is a difference and I still love my LWRC M6A2 but this gun was a next best thing and a best thing for a 5.45×39 upper.  You still can’t beat the cost of ammunition for these guns and the  caliber does have a better reputation than the 30 caliber AK.   I’ve known guys that took hits from the AK it has so much energy that it just zips through you and the Russians finally caught on that the 5.56 was a better combat caliber.

So many choices and so much good stuff!

Instead of getting a new AR15 upper receiver with a longer or shorter barrel, instead of buying a better quality bolt carrier group or doing some minor tweaking, just change the furniture.    Magpul industries is King of the AR15 accessorizing and the new MOE products really do give you something new to adjust to.   We have a blue rifle that we attach accessories to and let our customer hold them in their hands and try them out.   All gun grips should be customized by the shooter because just like footwear, our feet as well as our  hands come in different sizes, so why would we issue the same size rifle stocks or attachments to a Carbine.

A good operator knows that this is true and each of us has to be able to adjust our accessories to the job that we intend to do with our Carbine.  We have sold a lot of CMMG and Spikes Tactical uppers as well as many of the higher end AR15 uppers like LWRC and Noveske.   There isn’t really much of a difference between these guns as far as reliability, but there gas piston guns are much lower maintenance.  This year Spikes Tactical uppers have been so hard to acquire that many have actually chosen to save up their money and pick up piston driven uppers.  We’ve sold more LWRC M6 uppers this year than ever before.   Stay tuned for the new M6A5 coming out later this summer.

Long range shooting with an AR platform rifle

I don’t know all of the facts and figures, but given just what I see every day on the New York and Ohio firing ranges around here, I would say that the AR15 is the most popular rifle in America.   Now that caliber changes are as easy as swapping out your AR15 upper receiver and possible only a minor change in your lower receiver like a hammer spring, you can go from a .223 varmint rifle to a 6.8 SPC rifle, or down to a CQB rifle at almost the pop of two pins.   I was never a big fan of upping the caliber on a AR15 rifle, but I am a big fan of the 75gr HPBT for close up fighting.   The 75gr bullet seems to yaw better and slower velocities and give more thump just from my experiences.

When it comes to taking your AR15 rifle to a longer range, there are records being broken every week with the AR15 platform.  People use to laugh when they would hear of some one shooting an AR15 at 1000yds,  but it is done and can give a .308 a run for it’s money.   The real thing to consider when it comes to caliber changes on AR15 upper receivers  is how powerful is the round vs just accuracy competitions.   I have a friend that came back from service over in the Middle East and he gave first hand accounts of how bad 9mm ammo was in combat and that at least 3rds of M855 was necessary to take down a threat with an M4.   Consider the ammunition you are using and not just how far out you can shoot, you may want to trade accuracy for energy.

Getting the most out of the .223 gun

Even if you are someone that get’s very accurate results from your M4 or 14.7 inch barrel AR15.   You may be getting hits, but that caliber can become very weak once you get several hundred yards out.   When I picked up a chronograph I was blown away by how much velocity I actually got out of short barrel handguns and my M4 rifles because it did not match up with what I previously read about on the internet.   I saw 75gr HPBT clock at 2900fps out of my guns when I thought they would have been close to 2750.   I know you can push the limits with hand loaded ammunition, but you do have to be careful about excessive wear and tear.

I have been recently thinking about picking up an LWRCI Repr because I have been a big fan of battle rifles and even the military has brought back the 7.62 DMR rifle in various configurations.  I have even seen a few British troops show up with FAL rifles with scopes on them.   There is also a difference between what you can get out of a 55gr hpbt and a 75gr hpbt out of a 5.56 gun.  Sometimes an 18-20 inch AR15 upper receivers will get you far more range and punch than M193 ball ammo.  What you can do at 400-800yds with those guns compared to a 55gr bullet is considerable especially with wind drift ect.   Of course much of this is up to the skill level of the shooter.

5.45×39 upper receiver options

I recently got to witness the Smith & Wesson 5.45×39 in action a zombie shoot competition.   This upper has been on the market for a few years, but in all honesty I don’t know anyone that has actually put one to hard use.   I always thought that the direct impingement design didn’t lend itself very well to Russian ammo.  Many AR15 jam up and do not work very well with Wolf ammo and from my experience there are more FTF when mixing Russian ammo with American guns.    Not only do many of these guns fail to fire, the ammo is ditier and can cause failures to extract.  Sure you can always get around some of these issues by constantly cleaning,  but I wouldn’t expect my AR15 to be combat reliable with Russian ammo, especially when the round count gets up there.   We’ve sold a great many upper receivers in the 2010 and the Smith & Wesson 5.45×39 is the number one seller.

Smith & Wesson 556 guns were one of the best made guns in 2009 and many of my fellow firearms instructors will testify to this.   Even though there are still some issues with the DI type guns, the guns being made today are superior to the AR15 DI guns from 10yrs ago.   LWRCI has their own short stroke piston upper receivers in 5.45×39 , but from what I have seen in the firearms market, I don’t jump on the bandwagon with new guns until they’ve been out in the field for several years.   I saw changes to firearms from Rugers LCP and LCR  and even the Springfield XD guns were all slightly modified after being out for only a year.   Let the feedback from the end user determine which guns are better unless you want to be the beta tester.

Downgrade the rifle length and upgrade the caliber

AR15 UppersThere is much to debate when it comes to discussing the effectiveness of the 5.56 round.   When it was originally deployed in the M16A1, the military had issues with the reliability of the gun, but I have heard not one complaint from any Vietnam vet about the lethality of the round.   That was when the military was using a 20inch barrel with a 55gr bullet travelling well over 3000fps.  The bullet is extremely violent at that velocity.   The lethality of the round was greatly diminished when the military started using shorter length barrels and the 62gr SCBT also known as SS109 or M855.   Although it is only 6grs heavier, the bullet is so well balanced that it basically zips straight through a target and the terminal ballistics are not very good below 2800fps which is practically what an M4 shoots it at near the muzzle.

In my opinion and many others that have been to Iraq, the short way to get around the probable is to use a heavier bullet.   The MK262 is a 77gr bullet that although it does not travel as fast as the 55gr or 62gr, it is much longer and tumbles almost immediately after hitting a target.  For close quarters situations I recommend 75gr-77gr HPBT.    One other thing to consider that many in the Special Forces or Civillian area are doing is upgrading their M4 or AR15 Uppers to the 6.8 SPC.   Do some research on which kind of upper configuration  you are looking for because there are  a lot of manufacturers out there.   The CMMG Upper is a quality upper that will get you in the new realm of M4 Carbine upgrades.

Complete your CQB Skills with an M4 Upper

AR15 UppersI was never the one that was into the tactical doodad thing when I got into shooting AR15 rifles.   My idea of a rifle is a 30/30 or a M1 or FAL rifle.   I understood the ballistics of the .223 round and knew what is was good for and always thought that I should stick with the 20 inch heavy barrel for the best terminal ballistics.   Well, then I actually started learning about close combat and understood that toting the longest barrel gun and the heaviest barrel is going to mean slower speed and too much weight.

The M4 is hands down the best close quarters combat Carbine.   I have trouble referring to the M4 as a rifle, but I think that it really isn’t.   The beauty of the AR15 family or rifles is the easy swap in swap out changes you can do with an AR15 Upper.   AR15 Uppers are made by dozens and dozens of manufacturers and the quality and design differences are very diverse.   LWRC is making what I believe is the best M4 style carbine for US Citizens, but CMMG, Bushmaster, DPMS are making less expensive yet combat worthy AR15 Uppers.   Understand what the M4 is designed for and using the proper ammunition will put you in a much better position that using a handgun for those environments.
