Recently, had a bit of debate on our WarriorTalk forum about the usefulness of mildot scopes. Mildot scopes are important enough I thought they deserved a full article, rather than just a forum post. The ‘mil’ in mildot is short for ‘milliradian’. It’s an angular measurement, like a degree but much smaller. A milldot scope has a reticle that’s graduated in mils, using dots along the crosshairs as markers (hence mil-dot). While mildot scopes are the most common type of scope with this sort of graduated reticle, the advantages we’re talking about can be applied to any graduated reticle scope.... Continue reading

As soon as the first TSD MAG-15s came in we shipped them out to our friends in the US Military community for testing. Here is a write up that was sent to us, and posted at warriortalk.com, on their torture testing of the best magazine for the M4 system. Here is his commentary. By the way…notice the TSD Combat Systems RMR Glock 19 in the pics? Ok guys I want to share some of the torture testing of the TSD-MAG15 magazines that we conducted yesterday. Basically what we did was treat one of the new mags very vary badly and... Continue reading

I recently attended the Guerrilla Sniper class that Gabe Suarez taught in Kingman, Arizona. This is not a new class for me, I’ve attended the with Eric Pfleger in Ohio, and with Scott Vandiver in Georgia, along with Gabe’s Guerrilla Sniper II class last fall here in Kingman. However, it's always one of may favorites. Gear My main rifle for this class was my PTR–91GI. Last fall I sent this rifle over to Investment Grade Firearms to have them install a picatinny rail on top of the receiver for mounting optics (they also added a paddle mag release). Gabe was...

Last weekend I had the opportunity to attend John Chambers’ M4 Sniper Week - Designated Marksman School in Coleman, Texas. This is a five day class combining his DMR and Advanced DMR classes. John is a graduate of the Army's squad designated marksman training program and served as a designated marksman. Most of his service was in a Long Range Surveillance Unit, which has a lot of applicability for the sort of guerrilla small unit tactics that Suarez International teaches. He is exceedingly well qualified to teach a course like this. Gear This was not an easy class to fly... Continue reading

by Chris Upchurch, Suarez International Director of Marketing The Electromagnetic Spectrum Radio waves, microwaves, light, x-rays, and gamma rays are all basically the same thing: electromagnetic radiation. The difference between the electromagnetic radiation we use for transmitting music through the air, cooking food, lighting up a room, or looking at a broken bone is the frequency of the radiation. Our eyes pick up only a very small slice of this spectrum, what we call visible light. Within this small slice, we perceive different frequencies as different colors. The portion of the spectrum we can see makes up the colors of... Continue reading

by Chris Upchurch, Suarez International Director of Marketing I have to admit, it took a while for me to really warm up to the FS2000. When one came in for Gabe back in August, my first thought was ‘wow, what a space-gun looking thing’. I handled it a bit and it seemed very odd and unfamiliar. It just has such a different layout and different controls that it was way outside my previous experience. As much as we make of the difference between, say, an AK and and AR, they both use basically the same layout. By comparison a bullpup,... Continue reading

Last weekend I attended the inaugural Guerrilla Sniper II class. I first took the original GS class from Eric Pfleger in Ohio over Fourth of July weekend in 2011. Last December I sat in on it again from Scott Vandiver in Georgia. This is an area where I'm just a beginner and I'm really eager to expand my skills. When Gabe announced Guerrilla Sniper II, I signed up immediately. Gear As always, GS is a relatively gear intensive class. My setup hasn't changed much since the GS class in Georgia last year. I brought my Savage Model 10FP in .308.... Continue reading

By Chris Upchurch, Suarez International Staff Instructor Last weekend I took the Terrorist/Active Shooter Interdiction class from Jack Rumbaugh. This class is a bit different from the standard S.I. fare: rather than focusing on fighting with a particular weapons system, it examines a particular sort of situation in depth: someone with a gun whose goal is to kill as many people as possible. This is a class I've been wanting to take for quite a while. This was the first time it's been taught by anyone other than Gabe. For the live fire portion of the class, I brought a...

It's better to do things than to buy stuff. I figured this out about five years ago and it's tremendously enriched my life ever since. I still buy stuff, but I generally try to only buy stuff that will enable me to do something that I'm really interested in.

All this commentary on the weakness of MD-5 and SHA-1 and no mention of NIST's competition for a new cryptographic has algorithm? http://csrc.nist.gov/groups/ST/hash/

By Chris Upchurch, Suarez International Staff Instructor Last weekend I was at the Guerrilla Sniper taught by S.I. Instructor Scott Vandiver in Blakely, GA. This was a really great class and I have to say I had a real blast. I really enjoyed the Guerrilla Sniper class I took from Eric Pfleger last year in Ohio. When I heard Scott Vandiver would be brining this class to Georgia, I knew I wanted to get in on the action. He was generous enough to let Alex Nieuwland and I come down to assist, and to send some rounds downrange as well.... Continue reading

By Chris Upchurch, Suarez International Staff Instructor Earlier this month I had the opportunity to assist with the Force on Force class that Randy Harris taught here in Columbia, SC. Force on Force was one of the very first S.I. classes I took back in 2007. While the fundamentals are still the same, the class has evolved quite a bit since then. The other host for the class was fellow S.I instructor Alex Nieuwland. We were also joined by S.I. Staff Instructor J.D. Lester. Both of them took the course as students. There were nine other students, including some repeat... Continue reading

Over Memorial Day weekend I attended Randy Harris' AR15/M4 Rifle Gunfighting class. This will be is a bit different from my usual after action reviews. I was not actually a student in this class. Instead, Randy was nice enough to let me sit in as an 'Assistant Instructor', which essentially meant that I watched Randy teach the class, helped run the firing line, demoed stuff, and offered the occasional comment from the peanut gallery. Why spend a weekend over in Chattanooga doing this? Well, back in February I taught a Fighting Rifle Skills class and one of the students brought... Continue reading

Chris Upchurch – Suarez International Staff Instructor Suarez International’s CQB: Fighting in Structures class is a bit different from most classes we teach. It involves no live fire and, at most venues, no force on force either. While there are some physical aspects to it, this is much more of a mental skill. As Gabe puts it, CQB is more like chess than MMA. Because CQB is a non-shooting class, we don’t have any prerequisites for it. There’s no safety reason to require any previous experience or advanced gunhandling skills. That said, to get the most out of it, you... Continue reading

Chris Upchurch – Suarez International Staff Instructor In Part 1 of this series, we talked about how many people are under the false impression that CQB is just for SWAT team members and the military. In reality, these skills are vital to anyone who owns a firearm for self-defense, particularly for the bedrock purpose of home defense. Unfortunately, many firearms instructors seem to be under this same false impression. Often their CQB classes are limited to law enforcement and military only. Even when they’re open to the common citizen, the techniques and tactics they teach are often predicated on military... Continue reading

Chris Upchurch – Suarez International Staff Instructor To some, Close Quarters Battle (CQB) seems like a very high speed-low drag skillset. Something more suited to SWAT teams and the military than the common citizen interested in self-defense. This could not be further from the truth. One of the biggest reasons people buy firearms is for home defense. Knowing how to fight in this environment and to use your home’s ‘terrain’ to your advantage is vital. Consider the following scenarios: You are awakened in the middle of the night by the sound of breaking glass, followed by the alarm going off.... Continue reading

by Chris Upchurch, Suarez International Staff Instructor This weekend I attended a Shotgun Gunfighting class taught by my fellow SI instructor Alex Nieuwland. I’ve taught classes with Alex many times, but this was my first opportunity to be his student, rather than a co-instructor. Being able to take each other's classes gratis is one of the benefits of sharing instructional duties for South Carolina. I've had a little bit of formal shotgun instruction, but not much. I’m really more of a rifle guy than a shotgun guy. If I need to grab a long gun to fight for my life,... Continue reading
