Muzzle velocity is a critical component to plotting the ballistic trajectory of a precision rifle. It is easy to look up the dimensions and ballistic coefficient of the bullet you are shooting. However the muzzle velocity is unique to each rifle. You cannot rely on velocities printed on cartridge boxes or even the numbers your buddy gave you for his pet load. The easiest way to obtain an accurate muzzle velocity is to measure it with precision equipment. The Magnetospeed V3 Chronograph makes this a simple task.

Early in November, Nightforce was kind enough to invite us to CORE Shooting Solutions in Baker, FL. to check out some of their new products. There was an update to the SHV 5-20×56 elevation turret, a new reticle (Mil-C) and a slick new Nightforce branded Carbon Fiber Tripod. Those were interesting, but the star of the show was the new ATACR F1 7-35x56mm. Continue reading First Look: Nightforce ATACR F1 7-35x56mm
When you carry a handgun for most of your waking hours a good belt is a critical component. Much like the “perfect” holster, shooters are always on the hunt for a better belt.
One of the problems that I frequently encounter with stiff “tactical” style web belts, is that I either cannot get them tight enough or they work loose. Leather “buckle” style belts often cause you to choose between one hole or another (or punching your own hole). The Nexbelt is advertised as being able to solve both of these problems.
Nexbelt was kind enough to send us one of their new Titan BD Tactical Ratchet Belts to review. I have been wearing the Titan BD daily for several weeks now both in my daily routine and at the range. This is quickly becoming my belt of choice. Continue reading Nexbelt – We Review The Belt with No Holes
Some time ago I had an online conversation with one of our viewers about the Atlas Bipod, produced by B&T Industries. Kasey at B&T has been a long time supporter of what we do and his company produces as solid product that has been supporting rifles, killing bad-guys at home and abroad for many years. In addition, B&T Industries is a huge supporter of Precision Rifle Matches. It has become commonplace to see a “Ace of Spades” stage at the start of the match, with the chance of winning a bipod.
Our viewer lamented that the Atlas was too expensive for his income bracket and he had purchased a copy from Amazon for much less. Continue reading Counterfeit Parts, The Atlas Bipod Confusion.
As a precision rifle shooter, I am a bit of a trigger snob. I was forced to qualify in the Marine Corps with a rack grade M16A2 with a horribly gritty trigger with loads of creep. Whenever I hear the term “USGI Trigger”, I always think back to those ugly triggers. This reaction caused me to put off looking at the ALG Defense Advanced Combat Trigger. The ALG ACT is essentially a USGI type trigger with a couple of added features. After using the ACT, I may have to re-evaluate my prejudice against USGI type triggers. Continue reading ALG Defense Advanced Combat Trigger (ACT)
We have been using the Pmag 17 GL9 in our Glock 17 for several months now. In competition and training we have put thousands of rounds through them without issue. When Magpul announced the release of the Pmag 21 GL9, we rushed to get our hands on one.
The Pmag 21 GL9 looks identical to the Pmag 17 GL9. The Pmag 21 extends from the bottom of the Glock 17 in order to make room for those four extra 9mm cartridges. The Pmag 21 also has 10, 15 and 21 round witness holes in the side.
The Pmag 21 GL9 uses the same floor plate as the Pmag 17. This includes the “dot matrix” marking area. This also means that the Pmag 21 will accept the Magpul L-Plate rubberized floor plate. If you are not forced to work within competition magazine length rules, the L-Plate is a worthy upgrade for these magazines.
We ran the Pmag 21 GL9 hard for 150 rounds to get a feel for the reliability. We did not have a single stoppage that I could attribute to the magazine. The mag-dumps were flawless. We ran 50 repetitions of “one-shot” drills to see how reliably the Pmag 21 would lock the slide back on our Glock 17. We only encountered one instance where the slide failed to lock. We could not reproduce the error.
If you have a need to gas up your Glock with 21 round magazines, the Magpul Pmag 21 GL9 is a great option. At $19.95 MSRP they are the most cost-effective method at increasing the magazine capacity of your Glock. Hopefully Magpul will have the 27 round version out soon!
Over the years I have used many different flashlight techniques while shooting a handgun. The “Chapman”, “Harries”, “Rogers”, “FBI”, etc. all work with varying degrees of efficiency. All take away points of contact on the handgun when compared to a standard two handed grip. This drawback paved the way for weapon lights to take over the professional sector.
In the concealed carry world, a weapon light causes some new difficulties. Weaponlight holsters are bulky and most sub-compact handguns are not designed to accept weapon lights. Now we are back to having to use one of the old-school flashlight techniques, while minimizing loss of contact on the weapon.
Thyrm LLC’s SwitchBack helps to solve some of these problems. The SwitchBack is a simple polymer ring that slips over the tail cap on a variety of popular tactical lights.
In use, the index finger of the shooter’s support hand goes through the loop with the rest of the flashlight body pointing down in the palm of the hand. This is what I refer to as the “utility” grip. During my testing, I found that it is a very secure way to hold the light for most tasks that do not involve a firearm. For regular searching I would hold the flashlight in the center of my chest, palm down. If I needed to draw my handgun, but did not have a threat, then I could use the “FBI Technique” where the light is held high and away from the body.
When it was time to bring up your handgun and light up a target, you allowed the light to rotate around your index finger, pivoting on the ring. This brought the tail cap switch into contact with your middle finger. The “bump” on the ring falls perfectly under the pad of your thumb. In this position, pushing forward with your thumb causes the light to pivot on the ring and press the tail cap switch, momentarily illuminating the light. I will refer to this as the “tactical” grip.
Once you have the light in the “tactical” grip your middle, ring and pinky finger are free to wrap around your strong hand and assist in keeping your weapon on target. In use I found this grip to be much more stable than the G2Z in a “Surefire/Rogers” grip.
During our test I installed the Thyrm LLC, SwitchBack on a Surefire G2X light. Initially we used the stock Surefire momentary switch. At first the switch was very hard to depress, but as it broke in it became easier to activate the light in the “tactical” position. Later we swapped out the factory momentary switch for a “clicky” switch. This made is easier to activate in momentary on. The fit of the SwitchBack on our G2X made it almost impossible to twist the tail cap for constant on. The installation of the “clicky” switch solved this problem. I definitely suggest using an aftermarket “clicky” switch or selecting one of Surefire’s other models if you intend to add a SwitchBack.
Thyrm LLC was also smart enough to add a pocket clip to the body of the SwitchBack. This clip makes it very easy to keep the attached light high in a pocket for quick deployment. In civvies, it allowed me to clip the light in my support side pants pocket with no problems. I never once had anyone ask about it. In uniformed use, it clipped perfectly inside my cargo pocket divider on my 5.11 Stryke pants.
The biggest benefit to a non-weapon mounted light is during non-gun situations. Sometimes, 500 lumens of white light may be enough to discourage whatever antisocial behavior had arisen. Other times I may require a more personal non-lethal response. When going “hands-on” the G2X and Thyrm SwitchBack have some added advantages. The G2X features an aluminum head and slightly toothy bezel. In a downward strike it can dissuade an attacker from continuing his hostile actions. When held in the “utility” grip, the SwitchBack places the thumb “bump” directly at the index finger’s middle knuckle. This could provide a focused strike, or even better apply a great deal of force to a pressure point for pain compliance. Thankfully there was not a need to test either of these features during this review.
With a $19.99 purchase price, the Thyrm LLC, SwitchBack offers a lot of value. Even if you do not currently have a light that the SwitchBack will fit, I feel it is worth the expense to purchase one if you routinely carry a non-weaponligth handgun.
The Glock 17 is arguably one of the most popular combat handguns since the 1911 or Hi-Power. They are relatively inexpensive, and easy for novices to shoot. While the handgun itself is relatively inexpensive, the magazines are not. Until recently, Glock has had a monopoly on magazines to feed your 9mm Glock. This has kept retail prices around $25 with LE pricing not much lower. This reason alone caused me to perk up when Magpul announced a Glock compatible Pmag.

Modular Driven Technologies is a Canadian based company that has been making rifle accessories for some time now. In the past we have reviewed the LSS chassis and the HS3. After reviewing those systems, we received several requests to review the TAC21. The MDT TAC21 Chassis predates the LSS and HS3. It seems to sit at the opposite end of the design spectrum. All three chassis use AR type stocks and grips. The LSS and HS3 take an almost minimalist approach to chassis design. The TAC21 is a behemoth in comparison.
