Piston vs DI Dilemma: "The AR-15 Gas Choice" by Nutnfancy

Direct gas impingement AR-15s suck. Wait a minute, maybe that's piston driven AR-15s suck. Now that I have your attention I'll say they're both good and each has its own pluses and minuses that need your consideration. Long proven in many battles, the DI (direct impingement) M4/M16/AR-15 series are very reliable if maintained and lubricated properly. If it were not so it never would have lasted this long in US military service and many of the "it's broke, its needs replacing now" arguments ring hollow with me. That's not to say it cant have its problems and is failure-free. In the DI design by Eugene Stoner, the introduction of cyclic gas into the receiver makes things dirty and heats up critical components. That heat can accelerate wear and possible parts failure in extended full auto fire and makes cleaning a chore. Also running shorter barrel lengths on a DI gun is taxing to the system and it often needs heavier buffer, spring, and maybe even port adjustments to ensure reliability. Count on some tweaking. Also running a suppressor off a DI gun can cause debris and powder to be blown back into the users face, even with charging handles that incorporate deflection channels. The current piston AR-15s, like the Ruger SR-556 shown, promise to cure many of these problems. They transfer the heat and dirtiness up front at the regulator/piston mechanism, keeping the bolt cooler and cleaner. From my experience at this point, piston ARs will foul in the piston/regulator area and require similar cleaning to a DI gun in this area. But they function consistently with or without short barrels and/or suppressors and promise longer intervals without lubrication or service. But it's too early to tell if they are indeed the superior system. Some early designs have shown design weakness like spring failures in the piston transfer mechanism after high round counts. Other show carrier tilt resulting in shaving of the buffer tube. But the designs are being perfected and have measurable benefits in some POUs. So far however in most like comparisons, most have not been able to surpass the DI guns in terms of light weight. As a result, most DI guns usually have a faster swing and more manageable carry weight when similarly equipped. This leads to better mobility. In POUs requiring only semi-automatic and unsuppressed fire, maybe the DI is still the best choice and I predict it will remain popular and will never go away. If the user can take the added weight of a piston driven AR-15 then many will enjoy the cleaner bolt, promise of better durability, and taking the heat out of the receiver. But if weight and perhaps accuracy is your most critical attribute, a quality made DI AR-15 will still serve you well. //////////////////// Music: From artists Torley Wong and Jimmy G.

AK-47 vs AR-15 Part 3, by Nutnfancy

PART 3 of 4: Nutnfancy tackling the often controversial issue of the AK-47 versus AR-15 rifle systems. The bottom line is, a quality example of either gun can serve your law enforcement, military, and civilian sheepdog requirements admirably. However many factors and considerations should come into play when selecting your choice. When properly maintained and lubricated, the AR-15 is very reliable contrary to many internet, forum, and magazine myths. However it does not rise to the absolute, carefree ruggedness and reliability of the AK design. Whether packed in mud, neglected for cleaning, or just plain thrashed upon, the AK shrugs it all off and continues to shuck rounds with pleasing and life-saving regularity. It is better than the AR-15 system in that regard. However the AK design has many flaws which include: poorer ergonomics (like its munchkin length of pull), shorter sight radius and inferior sights, heavier magazines and ammunition, difficulty in mounting optics (less variety in application too), slower operational controls, and more recoil. But many accept these shortcomings to gain the increase in stopping power of the larger .30 caliber round. As shown in the video, this 7.62x39mm round pretty much dies after 300 yards but within its range, it hits hard and defeats obstacles much better than the smaller 5.56x45mm offering. However the AR-15 can easily be had in either a 6.5 SPC or Grendel chambering which nullifies this advantage (and the AK can be had in the 5.45x39mm load which has similar ballistics to the 5.56). Both systems enjoy adequate firepower, multitudes of accessory options, good service record (AK has better reliability record however), and similar value (subject to change). I respect the reliability, simplicity, ruggedness, and shooting fun of the AK design. For a mud gun, it still reigns supreme. However in terms of ergonomics, its amazing versatility, the lighter weight mags and its ammo, superior accuracy, and the longer range capabilities (especially with 77 gr loads), the AR-15 is a more capable weapons system.

"The Sheepdog Concept" by Nutnfancy

Your actions could save lives. At the heart of what I have referred to as The Sheepdog is a selflessness that looks outwardly to the needs of others. They cannot abide watching their fellow humans beings suffer and die while they do nothing. They are compelled into action even when those actions could lead to their own deaths or injury. The Sheepdog comes from every walk of life, every race, and can be male or female; it is impossible to identify them from appearance alone. It is their actions in the face of horrific situations that reveals the Sheepdog as they step forward when no one else will. Lenny Skutnik, in the face of the tragic Air Florida crash in 1982 into the icy Potomac River, was just such an unassuming Sheepdog. He jumped into the aviation fuel soaked and frigid waters to save passenger Priscilla Tirado just before she slipped beneath the water to her death. Hundreds had been watching Priscilla flounder and would have watch her die without doing anything. These are sheep that are frozen into inaction by their lives of denial and lack of mental and material preparation. They are not bad people but nore are they heroic; they're just there. Leeny's Sheepdog heart was revealed that day. They are others like him in civilian, law enforcement, fire fighting, and military ranks. But they are relatively few indeed and they are special. Few have what I feel possess the other key qualities of the Sheepdog (discussed in the video): a strong value system, unassuming manner, bravery, judgment and maturity, preparation, practiced skill sets, and a strong sense of duty in the face of often scary circumstances. The Sheepdog Concept is foundational to my gear reviews here: an attempt to give quality information to help equip you good people for your "day." Both mental and material prepartation can expand your capabilities in this important calling. Good Sheepdogs span the ranks and include responsible and caring civilians, law enforcement officials, firefighters, paramedics, PJs, EMTs, pilots, and soldiers. Many of these come to TNP to get this info as they equip and prepare. I try hard not to let them down. I salute them all and I myself try to aspire to their level. /////////////////// Music: http://www.partnersinrhyme.com /////////////////// Music: http://www.partnersinrhyme.com ///////////// Ret.

AK-47 vs AR-15 Part 1, by Nutnfancy

PART 1 of 5: Nutnfancy tackling the often controversial issue of the AK-47 versus AR-15 rifle systems. The bottom line is, a quality example of either gun can serve your law enforcement, military, and "civilian sheepdog" requirements admirably. However many factors and considerations should come into play when selecting your choice. When properly maintained and lubricated, the AR-15 is very reliable contrary to many internet, forum, and magazine myths. However it does not rise to the absolute, carefree ruggedness and reliability of the AK design. Whether packed in mud, neglected for cleaning, or just plain thrashed upon, the AK shrugs it all off and continues to shuck rounds with pleasing and life-saving regularity. It is better than the AR-15 system in that regard. It also features a lightning quick and easy fieldstrip. However the AK design has many flaws which include: poorer ergonomics (like its munchkin length of pull), shorter sight radius and inferior sights, heavier magazines and ammunition, difficulty in mounting optics (less variety in application too), slower operational controls, and more recoil. But many accept these shortcomings to gain the increase in stopping power of the larger .30 caliber round.
