Stag Arms and Ruger carbines were used during training at TDI. Ammo was from Hornady and Federal and optics used were from Aimpoint and EOTech.
Interest in the combative application of the “short” long gun is at an all time high. Better known as the carbine, the “short” long gun, has become one of the most popular guns available with the supply just now catching up to the demand. A year ago trying to buy an AR-15 with a short barrel and telescoping stock was a real challenge, unless you wanted to pay a premium price. While I certainly am not giving up my handguns for the long gun (I believe that is it far more likely that I will be armed with a handgun than a carbine when trouble comes) I have started to put in more training time with the carbine than I have in the past.
The Tactical Defense Institute (937-544-7228; tdiohio.com) in Southern Ohio has become one of the most credible institutions for advanced firearms skills in the nation. Founded in the 1980’s by owner and lead instructor John Benner, TDI has the reputation of offering a top-notch program for all levels of force, from verbal and open hand skills to the use of the carbine and precision rifle in the combative environment. Over the years, John has surrounded himself with a staff of instructors with military, law enforcement, competitive, medical and legal backgrounds, which allows him to offer a unique perspective. Full disclosure, John is a good friend of mine and I know his level of knowledge and skill is second to none, thus I headed to TDI when I wanted to enhance my own abilities with the combative carbine.
The first day started with a classroom session that discussed carbines and related gear. Chris Wallace and Lynn Freshley are both veteran law enforcement officers with an extensive amount of knowledge in carbine use. Freshley stated that the three primary features of any combative carbine are: reliability, accuracy and ergonomics — meaning the gun must fit the individual shooter. The instructors discussed the difference between the gas impingement and gas piston system and admitted that the impingement system was a “dirty” system, but also noted there was no “standard” gas piston system so parts were not universal from gun to gun or was there a Mil Spec standard. “As long as you keep the gas impingement system clean and lubed it will run without problem,” Freshley noted. Wallace warned the class against adding a number of unnecessary add-ons to your carbine. “All you need is a good trigger, good sights, good sling and a good light — and you will be good!” Makes sense to me.
The type of sight makes no difference to the TDI staff. While they prefer the Aimpoint system, they readily admit that Trijicon, EOTech, Burris and a number of other manufacturers make quality optics. However, “It is essential that you have a quality set of irons to back up your optics as you never know what will/can go wrong,” related Freshley — kind of hard to argue that point. In addition, the scope tube can be used as a sighting device at close range, what is known as “shooting through the tube,” something that was also discussed during a course I took at Crucible last year.
The number one problem relating to AR failures is the magazine, so buy good ones,” Chris Wallace stated. While all AR magazines look alike, the “innards” are often times very different, so buy quality. I have been using nothing but Magpul PMags for the last several years and I have had complete success with them. Some do not like plastic magazines and that is their decision, but when something works with totally reliability I don’t care if it is made from cow dung. One of the few times that John Benner spoke up in the class, he stated, “Learning what will work well for you and your gun is a big part of this class,” and that is a journey that we must all take as we attempt to build our skill set. The lecture concluded with a discussion of trajectory and wound ballistics, something that everyone should know but is too lengthy to discuss here. Take the time to search the Web for this information and know what your chosen round will do in your carbine.
We hit the range in a downpour of rain. As the cardboard targets “melted” off of the stands everyone in the class experienced one of the few downsides of having a glass optic…its real hard to get a clear sight picture with water literally running down the front of your glass! The remainder of day one was spent on the range zeroing the student rifles at both 25 and 100 yards. Like 9mm versus .45, some can hotly debate the distance at which a carbine is zeroed and I do not intend to go into that here. My feeling is that you must look closely at the environment where you live and work, and decide what zero distance works best for you. Once each rifle was zeroed, supported shooting was conducted at 200 yards to show each student how their particular zero would work at extended distances. While it is unlikely for me to ever use my carbine at such extended distances, it was interesting to see exactly where I needed to hold in order to hit such a long shot. The day concluded with long shots taken in supported and unsupported prone, supported and unsupported kneeling and supported and unsupported standing positions.
