The heart of building my “Do it all” carbine is the barrel. In order to get what I was looking for in a very lightweight and handy carbine that carries and shoots like a light M4, but offers better penetration and performance than 5.56mm and hits like a light .308. I also wanted to avoid the many issues of a short-barreled 5.56mm or for that matter, a short .308 (excessive blast, recoil and accelerated wear). I was fortunate to locate the perfect person to get my new little carbine to where it has a near perfect level of length, weight, and balance. Continue reading

Building the “Do it All” Carbine
Since moving to Texas I have immersed myself in not only trying to learn the intricacies of Texas pronunciation of various cities and Texas terminology, but also Texas history. One of the things I have found in looking at Texas lawmen history and the gun culture here is the use of the do it all carbine. In particular, the 30/30-lever action has played a prominent role. While many legendary Texas lawmen would go to the Winchester Model 95 as the heavy problem solver, the 30/30 was sort of the day-to-day go to rifle for lawmen, ranchers, hunters, and everyday citizens for protection…a “knock around” rifle. The 30/30 has the ability to do good work on every type of game animal in the state, and also has a long history of working well on two legged vermin as well. It is a solid tool for the self sufficient Texan.

Initially available in black, with other standard colors to follow.
Geissele Automatics – Super Tricon Trigger
Every once in a while we have guest instructors come in to the Academy and teach their particular take on things. It is a nice perk of the job to be able to meet many of them and hear what they have to say on the various topics we all deal with on a daily basis. Several weeks back Jeff Gonzales of Trident Concepts stopped in to teach their Advanced Carbine class. Other than having taken his class and met him a few times, I barely know Jeff, so I spend my time in the background listening to the conversation. What came up during one lunch conversation was a discussion about AR platform rifle triggers and the new design TriCon had worked out with Geissele Automatics. The Super TriCon Trigger.

Alternative Carbine Training Options on a Budget
Thanks to the recent push by politicians to capitalize on the public’s emotions and institute further restrictions on law abiding citizens, along with the ever increasing cost of raw materials, ammunition is more expensive than ever. Around January, a 1000 round case of PMC .223 caliber ammunition was selling for nearly $2000 a case. Thankfully, costs have come down, but it is still difficult to come by, and a 1000 round case of factory training ammunition still costs upwards of $600-800. Training organizations have responded by allowing students to attend courses with .22 caliber rifles or conversion kits.
Here, we’ll take a look at a couple options that can help us maximize our training efficiency without breaking the bank on ammunition. Continue reading
Photo of the Day: Centurion Arms CMR 12-inch Rail
Centurion Arms has developed its latest hand guard system for the AR platform for 5.56mm and 7.62mm rifles. Boasting an extremely narrow diameter, it is approximately .120″ narrower in diameter (side to side) than a Troy Industries VTAC rail. The lightweight, custom barrel nut can be installed with a standard adjustable pin spanner wrench. Rather than attach sections of picatinny rail to the hand guard, Centurion Arms will be releasing mounts that will screw directly into the hand guard eliminating the need for an intermediate interface. The mount system is a hybrid design. It borrows the concept of the locking cross bolt system found in the H&K 416 and combines it with a clamp to the barrel nut. The tolerances are held tight and the hand guard is about a slip fit on the barrel nut prior to tightening. The mount mechanism is rock solid. As with all Centurion Arms hand guards, there are integral sling swivel attachment points at the front and rear at 9 and 3 o’clock. The entire rail is cleanly machined, extremely ergonomic, and attractive to boot. They should be hitting the market at any moment so look for it at your favorite dealer.

Review: Trijicon SRS Sealed Reflex Sight
I had an opportunity pop up a few weeks ago that allowed me to get my hands on the new Trijicon SRS (Sealed Reflex Sight). The 1×38 MIL-spec sight is about as rugged as they come. It is a parallax free, reflex sight with a large 38mm aperture for maximum visibility in a short body. The 1.75 MOA red dot has dual power illumination with 10 brightness settings. 3 of those are NVG compatible. The AA battery is mounted in line with the bore and assisted by the top mounted solar cell panel. The large buttons for adjusting the brightness levels are located on the sides of the housing and are easily manipulated with or without gloves. The overall build quality of the sight is what you would expect from a company such as Trijicon. The sight is robust with a housing so rugged that seems like the demonic offspring of a fire hydrant and a manhole cover. Continue reading
Review: Geissele Super Dynamic 3-Gun (S3G) trigger
To most people, a “match trigger” in a AR15 platform belongs on a rifle with a 16 to 22 inch precision barrel. During the course of my career I have shot the normal GI trigger that I was given. During sniper school the precision platform opened up to me, but the desire of a nicer trigger didn’t really bleed down to my other carbines until I shot a friend’s Geissele trigger a few years ago. I have since tried many “match” triggers of all types and from numerous companies, never really finding something I liked enough to warrant the additional funds.
I shoot a lot of 1911 like most of the other contributors on this site and personally use primarily a flat blade trigger. This preference of a flat trigger has bled down to my bolt guns as well. I learned that Geissele was producing a flat blade trigger and I had to try it, so I ordered 1 of every model ( Super Dynamic 3 gun, Super Dynamic Enhanced, and Super Dynamic Combat).

MAGPUL’S 20LR M110/MK11 7.62 MAGAZINE
Since the introduction of the PMAG in 2006, Magpul Industries has set the standard for reliable polymer magazines for the M16 platform. Prior to the PMAG, the best the market had to offer were from Thermold and Orlite, which were marginal at best. The use of polymer for magazine bodies have definite advantages in weight savings and durability, as seen in our Magazine Drop Test. The PMAG has earned itself an excellent reputation among end users, many of whom prefer the polymer PMAG over USGI aluminum magazines. While I believe aluminum USGI magazines have their place, the current generation PMAG is an excellent choice for a duty magazine.
Carbine Training: The 18 Drill
The 18 drill is one of my old standby’s. 18 yards, 18 rounds, 18 seconds, 18 inch aiming area. Sound pretty simple?
This is a carbine drill that is shot from three positions- standing, kneeling and prone.
To set up for the drill, the shooter loads three magazines with six rounds each. One is inserted into the gun and the gun is charged. The other two are placed somewhere on the body for two emergency reloads. The shooter starts in the standing position, facing the target, safety on, gun in low ready. On the tone, the shooter fires six rounds standing, performs an emergency reload, and goes to the kneeling position. From the kneeling position, the shooter then fires six rounds. The shooter performs an emergency reload, and then goes prone. The shooter then fires his/her remaining six rounds. Time stops on the last round fired.
We score it as all or none on the target. The run has to be “clean” with all 18 rounds inside the aiming area. Usually we shoot this on the B21 target with all hits to be inside the “coke” bottle (a little more generous than a true 18 inch circle) or anything in the “Down One” or “C” zone on a IPSC or IDPA target. The “Down One” or “C” zone is larger than 18 inches, but with a little ingenuity, you can make the scoring work with just about any target, by adjusting the target area to fit.
Your Patrol Rifle: Cruiser Carry
I first heard the term “Cruiser Carry” many moons ago when I was in the Academy. “Cruiser Carry” at that time was used to describe the condition of our Remington 870’s when stored in our police cars.
Then came the Patrol rifle. We in the firearms training community adapted “Cruiser Carry” to the rifle. There are a few different versions of “cruiser carry” but here is what we currently teach around here. Continue reading
YOUR PATROL RIFLE (HOW TO SET IT UP)
Patrol rifles are steadily becoming the mainstay of the modern police arsenal. From time to time, the conversation of chosing a police patrol rifle comes up. And some folks have some interesting thoughts on the modern police patrol rifle, and what should hang on it. Folks have all kinds of ideas ranging from a full auto rifle chambered in a piston driven 6.8, to hanging on a 2-16 Nightforce scope, two lights, a PEQ, weather vane, Iphone attachment (let’s face it EVERYTHING revolves around ITunes these days), gerbil ball, bipod, monopod grip in case the bipod fails, a suppressor, one of those window hanger thingies to hold a Monster Absolute Zero, and two Surefire 60 round magazines taped end to end for good measure.

Geissele Reaction Rod – Review
I spend a lot of time behind my rifles, which means I spend a fair amount of time building, cleaning and maintaining my rifles. Anything that I can find that has the potential to help make my life easier or that saves time, I am willing to give a try. I read about the Geissele Reaction Rod and about how the AMU’s armorers were using something like it several months ago and had been waiting for it to be released ever since. Santa was good to me and I have been working with this new tool for the past few weeks. Continue reading
THE M4 BOLT: GAS RINGS
In my Three Day Patrol Carbine Course, I cover quite a few topics, specifically concentrating on end user needs. Maintenance is always covered. I like to clean quickly while being thorough. During cleaning, it’s important to check key areas to ensure your platform will continue working for you.
Make no mistake, I like a quality carbine/rifle. It’s my life, so I don’t take short cuts. No matter which make/manufacturer you choose, you need to care for your weapon no matter which manufacturer you choose. Continue reading
AR Issues? Use MEAL to solve your problem.
Recently, I received a call from a local department armorer that had attended a course I a taught several years ago. He needed my help. He explained his problem: During qualifications they suddenly began experiencing malfunctions with several carbines while qualifying. The armorer described that he had found a piece of the bullet inside of the lugs on the barrel extension. They tried different types of ammunition and were still experiencing the same issue.
I asked him to stop by the range and bring the carbines and ammo in question.
When he and his partner came by, I looked at the carbines and immediately disassembled the weapons. I felt we should change out the gas rings on one and the extractor springs on both. However, I wanted to shoot the carbines before making any changes so I could diagnose the specific problem. Continue reading
