Do you shoot AR15 much? How about for those that have shot the standard M4, do you find having the charging handle at the rear cumbersome? Especially, when you get a malfunction while shooting rapidly during a competition or target practice.

Companies such as ADCOR, Dead Foot Arms or JP Enterprises offers a side charging handle on the upper. Which many are saying is a game changer or its just easier to work the charging handle when the malfunction happens. Don’t take our words for it, here’s a test that Youtuber U.S. Warfighters did.

U.S. Warfighters conducted a side-by-side test, putting the standard rear-charging handle of an M4 against the ADCOR forward-charging handle. They evaluated the time and easiness of clearing a failure to fire exercise. In a 30-round magazine, every fifth round was a dummy round, and then a straight-up speed test, again 30 rounds.
There were standard triggers in both rifles, using a standard Magpul 30-round magazine. Both rifles had an Aimpoint H-1 Micro sight on board. On the battlefield, in competition or in defense of your home and loved ones … which rifle would you rather have in a gun fight? You be the judge.

Comparison in Speed
M4 – 16.53 seconds to go through a 30 round mag with dummy rounds. (every 5th round)
ADCOR – 14.08 seconds, which is a 2.5 seconds faster.

Striking Surface

In our past Karambit article highlights Doug Marcaida demoing the application with the blade side. This segment we want to explore a little more on the impact side, there are instances where you do not need to deploy the blade.

For those that study Filipino Martial Arts, this article may be slow for you. We wanted to approach this for someone that’s an LEO or private citizen with an average personal defense skill knowledge level.

ASJ approach is to convey this skill set to any level of expertise so they can train and have fun quickly. Doesn’t require you to practice 20 hours a week to be proficient, only 5 minutes to learn. But, does require you to put in some hours of hands on time. That’s just the reality of it, if you want to be better.

coverBlock & Strike
Here’s the meat of the article, block and strike. There are many types of blocks, we are only using a basic cover by bringing the hands up to cover the face with elbows pointing forward. From there you work the timing of block and hit with the Karambit. Targeting the typical facial area. Concentrate on doing multiple strikes that combines the use of Karambit and your other hand. Strikes with Karambit aren’t meant to be knock out punches, these are designed to inflict pain with their hard surface and can possibly cut the facial area.

Defanging the Snake
The term “defanging the snake” comes from the Filipino martial arts system to neutralize the hand (arm) that wields the stick, knife or punch by attacking it directly. This part of the strike is to target the hands, wrist, forearms, biceps and shoulders with hard points of the Karambit. There is nothing mystical about this concept, we are not going after any pressure points, which you can if you have been trained. Again, we are going after these areas as secondary targets and this is what drives the attackers punch delivery system. These tactics are used to supplement your blocking with a little pain inflicting strikes. These strikes to the limbs are not designed as a knock-out blow. If you put some pain into these areas the attacker won’t bite you as hard.
A final note on training with the Karambit always train with trainer knife version such as the FOX 599TK. This will mitigate injuries and accidents against using live blade.

Doug Marcaida is a military contractor in edge impact weapons systems and weapons of opportunity. In this video he shares a few tips on how to survive a life and death fight. Please note that while Doug trains civilians through international seminars and the military curriculum is vastly different and may not be broadcast on YouTube. This video is just the tip of the iceberg on street survival.

The video below highlights awareness as the theme to all altercation. Maybe Miyagi quote is always best, “Best Defense don’t Be There”.
