AK or M16? AR-15 for 7.62x39!!!

All of us are perfectly aware of the oldest and longest debate among tactical weapon professionals and fans regarding which rifle caliber is the best in practice and detail. Some of us believe AK is the most functional. Others that M16 rifles are the best. And all of us give hundreds and hundreds arguments to support one way or another. All we know, this dispute might never end. Until now.
Today, we have an amazing possibility to unite all positive characteristics of AK and M16 in one weapon, the one called 7.62x39.
As you may know, according to the tactical conditions of the city battles, Russian 7.62x39 is considered to be a much better version than .223 Rem for city tactical operations. It has a more powerful ammo for short distances, and  has magnificent references from city tactical specialists.
Thereby, Moriarti is proud to present the line of tactical weapons build on the classic AR-15 platform for 7.62x39 ammo. You can enjoy these tactical rifles with 16” and 18” stainless steel chrome lined barrels. We also offer tactical pistols with 10.5” and 7.5” inch barrels for 7.62x39 caliber.  They are precise, mil spec, and amazing in look and feel.
In our opinion, it is a perfect weapon that utilizes the power of 7.62x39 with precision of AR-15 has to offer. This is yet an unsurpassed weapon, has huge bullet power and amazing  precision on distances to 1000 feet. This weapon is much lighter than AK, but it has the same power and much more precision.

5.56mm vs 6.8mm: YOU DECIDE!

There has been long running debate over which is the most effective round and what our ground troops should be using, 5.56mm x 45, or 6.8mm x 43 SPC.

Well, for me, that’s a no brainer – 6.8mm of course.
Why? Because of its terminal effects! In layman’s terms terminal ballistics is how the projectile reacts and what damage it causes when it strikes the target.
But don’t let me influence you in any way with my opinion; I’d like you to put your reasons forward as to which round you think is more suited for our troops.

5.56mm and 6.8mm Rounds: The Facts

There are many ballistic charts that you can view on the web, most showing that velocity is reasonably similar between the 5.56mm and 6.8mm rounds. Compare a 77gr 5.56mm projectile against the 115gr 6.8 and it is very close indeed, however kinetic energy is anywhere from 40-50% greater at shorter ranges, and up to 35% out to 600 yards.
The 6.8 SPC round has the same energy at 250 yards as the M855 has at the muzzle. At 600 yards it has the same energy as a 7.62mm M43 at 275 yards, M193 at 250 yards and M855 at 375 yards. Since the 6.8mm is of a larger calibre and greater sectional density than the 5.56mm, it will use this energy more effectively when producing terminal damage. Performance can be increased slightly by using 110gr ammunition, giving you more velocity and less bullet drop over range.
The lower velocity of the 115gr ammunition combined with more kinetic energy makes this round less susceptible to deflection from soft cover such as foliage, shooting through glass (in the case of vehicle interdictions) and chest rigs.
6.8mm upper receivers will fit AR lowers, but you will need to change the bolt though and use specific 6.8 mags. I have fired 6.8 SPC ammunition from 5.56mm magazines but the heat that was generated expanded the mags – causing stoppages. The tolerances inside the mag are quite tight because the 6.8 cartridge is bigger in diameter. Although the calibre is larger, the difference in recoil is hardly evident and is quite controllable when engaged in rapid fire.
Ok, 6.8 will significantly increase your chances of neutralization or incapacitation with a first round strike. It goes without saying that different types of projectiles will produce different results, and that shot placement is still the key no matter what type of round is used. However, we can’t always achieve this, so the introduction of a large caliber that fills the gap between 5.56mm and 7.62mm is vital for the safety of our troops and is necessary in our fight against terrorism.
My guess is that money is the overriding problem. But perhaps it would work out cheaper to supply something that will do the job more efficiently without wasting ammunition…or lives!!
