The 6.8 SPC still not catching on

I was never a big fan of the .223 or 556 caliber until I actually got off the bench and started doing real gun fighting.   I started out like many, with a Russian AK variant which was extremely reliable, but when it came to target engagements out to 400 meters and for close quarters gun fighting, there was a substantial difference in hit ratio.  Hit ratio was something that I never dealt with before because it was all about penetration and accuracy.   Now I know that being able to shoot a reliable rifle doesn’t mean you are going to win a fight, it’s all about hits and who gets the hits first.

There have been times when an AK74 type of rifle has done almost as well or equal to an M4 Carbine, but the shooter has to have more experience in gun  handling skills to keep up.  I compared the close quarters hit ration of the 6.8 SPC and found it to be closer to a 7.62×39 AK than a .223 variant. CMMG upper receivers are something to be considered if you are looking to mess around with bullet calibers.  Muzzle hop or flip will affect  your accuracy and speed and that is something to be concerned about.  Room to room and house to house fighting is something which occurs in seconds and putting 5 hits on paper is better more reliable at stopping a threat than one bad hit.   Bullet penetration is also something that can be over blown when it comes to CQC because that is a bad thing in a hostage situation.

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.

Your AR15 is probable not the AR15 your father had

It’s funny making a statement like that because I still feel like the AR15 is a new gun, but the reality is that it is now something that many of us had in the 1980s and 1990’s and now we have kids that are shooting them.    The AR15 is now probable the most popular firearm being sold in the Country, not only can you use it for close quarters combat and house to house clearing, there are varmint versions that are extremely accurate.   The whole durability and design of the rifle has improved dramitically, even though the M16A2 has been in service for about 25yrs and is a considerable leap in reliability over the A1, other changes have been made.

Chrome barrels use to be the thing that helped keep the direct impingement guns in a better functionality, but gun magazine improvements have reduced the number of malfunctions I see by atleast 95%.   I don’t see the failures to feed or the double feeding that I use to and it’s primarily due to the Magpul P-mags.   These magazines feed better than most and you can drive a car over them and still have them work.  Swapping out the upper receivers on an AR15 involves pushing 2 pins out, and there are many configurations from CMMG, LWRCI, DPMS that will improve the durability over lower grade guns.  If you want a combat reliable AR15, you will probable have to do a few things to an AR15 that costs under $800 to get it up to par, but overall I am very impressed with the improvements I see across the board  in the AR15 community.

Is the gas piston a new thing?

I remember the first time I pulled the trigger on an AR15 rifle I thought it was the rich boy gun.   Back in the 1990s there was a mentality on the State Game ranges I use to dwell on where a certain level of snotty attitudes went with the expensive firearms.   Since just about everyone and there dog owns a 5.56 AR 15 now,  I don’t really look at it that way anymore.  The new trend in 5.56 calibers is to move away from the direct impingement and towards a gas piston driven gun.   There are plenty of people that can honestly claim that their AR15s don’t give them problems, but now that I know more about firearms, this is because they are maintaining their firearms properly.

Alth0ugh you can get the job done with a DI gun, I really have to say the that biggest reason I would want the United States Military to change to an H&K 416 style weapon is so our troops don’t have to break down their guns every day and do as much maintanace.    If we all drove a car that got 75 miles to the gallon, but needed an oil change every 500 miles, I think we get annoyed at how much time we are spending changing the oil filter or dropping it off to get done every month.  The beauty of market we are in is that piston conversion kits are being made for many of the DI guns and for a few hundred bucks we can convert everything over.
