What’s Wrong With Just Measuring Group Size?
This is something that is new to me. I have seen it for a while in the Ballistic-X app, but never really paid much attention to it. I have started to hear rumblings from people I respect about how this is the way, so I decided to do some research. This video podcast from Hornady is worth your time if you’re serious about shooting precision and want to truly understand how accurate your rifle and ammunition combination really is.
What’s Wrong With Just Measuring Group Size?
Most shooters are used to measuring group size by the extreme spread, the distance between the two farthest shots in a group. It’s easy, it’s familiar, and it’s what everyone has done for decades. Some with bullshit three shot groups like Mark Laure, and other with five shot groups, all the way up to 20 and 30 shot groups. But it’s also misleading.
Why? Because extreme spread is heavily influenced by just one or two outlier shots. A single flier, whether it’s caused by wind, user error, or an unpredictable round, can wreck your group measurement, even if the rest of your shots were tightly clustered.
Enter the Mean Radius: A Smarter, More Stable Metric
Hornady’s podcast explains how mean radius which the average distance of all shots from the group’s center, gives you a much more consistent and truthful picture of how your rifle and ammo are performing. It’s a statistical approach that reduces the impact of outliers and emphasizes the true average performance of the system.

What To Do When Someone Gives You A URX4 Keymod Rail?

KeyMod Isn’t Dead—It’s Just Misunderstood
Let’s talk to the younger shooters out there for a sec. KeyMod was actually awesome—yeah, it didn’t have the same pull strength as M-LOK, but when it comes to ease and speed of adding or removing accessories, KeyMod had it beat, and the Noveske KeyMod rail covers are the best ever made.
So why bring this up? Because KeyMod gets a lot of hate these days, which means you can score some insane deals on rails—or even get them for free, like I did.
I managed to pick up a KAC URX4 10.75” rail from one of those KeyMod haters at no cost. The cool part about the URX4? A pistol silencer tucks in perfectly underneath. Years ago (pre-COVID), I built a 9mm upper using this same rail with an AAC Ti-RANT 9 nestled right under it. That setup taught me two things: the URX4 is perfect for that kind of build, and I absolutely can’t stand direct blowback in 9mm—it’s just too much reciprocating mass and makes for a rougher shooting experience.
This time around, I’m giving it another go—but with a twist: CMMG’s radial delayed blowback system. Much smoother, in theory. Plus, CMMG’s AR-style 9mm mags work great in standard SBR lowers, which is a win.
I’ll circle back once the build’s complete and I’ve put some rounds downrange. Let’s see if this new setup lives up to the hype.

Leupold MK5 2-10 Overview
FIlling voids.
I have a Recce gun that I built long ago. It has been updated with a better barrel in a 16″ V7 match barrel (OG was a Larue Stealth Barrel). One Of my buddies at the time was a Master Gunsmith and he milled out a billet upper reciver for the rear anti rotation tabs on one of the old Geissele MK8 rails. The lockup of that upper to rail is about as close as your going to get to monolithic with having a match upper / rail.
Long story short the gun is a 1/2 moa 556 gun. I love it and probably dont shoot it enough. Clearly the rifle could run a 3-15 or 3-18 and be more of a precision rifle. But when it was built it ran NightForce 2-10 that I later replaced with one of the Gen 1 Vortex PST 2-10. I have tried a ton of scopes on this gun with no luck. Something about the 2-10, a crazy big eyebox, and the fact that with the mount, the optic only weigh about 22oz. 3-18 is heavier and and I dont really have an issue running the 2x in a CQB role but the 3x or 3.8x really forces me to have an offset RMR = more weight.
I have a Leupold MK5 3.8-18 on my SR25 and absolutely love that optic. With a T3 reticle it is fast, generally lightweight for that category, and easy to run (great eyebox, dials, illumination, precise clicks, capped windage, and a great magnification dial). Leupold recently came out with a MK5 2-10. But in true Leupold fashion the reticles suck as with 90% of their scopes. Either a simple duplex or some weird BDC and most things are in MOA not mils.
I recently got some time behind the 2-10 and it is a pleasure. The eyebox is massive which is great for a GP or recce gun as you can find yourself in some weird positions. Its a hard scope to understand its use case. Below is a video done by Mark Smith over at JBS Training where he walks you through why you may want the MK5 2-10 over say an LPVO 1-10. I will be all over this optic once Leupold get some decent reticles in it. But the video is worth your time:
Safariland Micro Rig
I have a bunch of Safariland holsters. I mainly use them on gun belts when doing training classes. The QLS system is pretty badass. You can easily move your holster from belt to belt by just picking up some cheap QLS Quick-KIT (eBay is your friend here). They also make it easy to swap holsters depending on what handgun you want to use that day. Safariland makes a number of leg rigs that accept the QLS systems but they are a little bulky. I get why, but they are overkill if you are just looking for a small, easy-on, easy-off rig for going to the range.
So under the heading of trying to solve a problem I didn’t know I had, OP Tactical (an awesome, old-school, online store for tactical goods) sends me marketing emails. A while back, they sent out an email for the True North Concepts Modular Holster Adapter. Adapters like these have been around for a while in either aluminum or 3D-printed versions. They allow for either a longer length to drop the gun farther down on your leg, or to combine two different hole patterns so you can mix and match holsters like a Blade-Tech or Blackhawk holster to a QLS pattern. The True North is more for mounting to a gun belt with the included aluminum belt clips that screw on and lock the adapter to your gun belt.
The thing that grabbed my attention, is that one of the pictures in the email had a Tek-Lok or DOTS belt attachment attached to mount to your belt:
If your not familiar with the Blade-Tech Tek-Lok or DOTS Ultimate Belt Attachment, they are a small clip that opens and locks around your belt. The Tek-Lok is a little bit more robust but a bit of a pain to get on and off as it has a safety mechanism that can be cumbersome to get at. The DOTS version just has a slider for locking the mount. If you have ever seen the holster for a Microtech Halo they come with kydex sheath that is attached to a DOTS belt attachment.

That picture got my mind pondering about a Safariland Micro Rig. A super small rig you could throw in your range bag and all you would need to add is your holster. No taking your belt off to thread through the holes in the Safariland drop leg holster. Depending on your belt choice that day that process can be a pain in the ass! This would allow you to just clip on to your existing belt and also take it off that easy. I had to try it out to see if it would work.
Cloud Defensive Chicro Admin Light Review
The most powerful Micro handheld light. Ever. – Ahh OK.
So I am a HUGE fan of the Streamlight 66608 MicroStream 250-Lumen EDC Ultra-Compact Flashlight. I carry one every day and have for a long time. Lights in general are going through a massive technological push. Companies like Modlite Systems and Cloud Defensive have forced the big boys like SureFire to step up their game.
Cloud Defensive in recent months has come out with a micro light to compete with the Streamlight. The light is called the Chicro Admin Light and supposedly has two advantages – USB-C vs the micro USB of the Streamlight and the fact that it is 350 vs the 250 of the Streamlight.
The Chicro is $50, which is cheaper than the MSRP of the Streamlight which I think is $58 but you can grab the Streamlight any day of the week for low $30s. Both lights are made in China.
Chicro Output & Specs (pulled from website):
- Length: 3.640″
- Bezel Diameter: .625″
- Weight (with battery): 1.05oz
- Output: 350 Lumens (High), 35 lumens (Low): 40% more lumen output than the closest competitor.
- Run-Time: 45 minutes (High) and 6+ hours (Low)
- Momentary and constant-on function.
- A reversible pocket clip for a variety of carry and user options.
- Fully rechargeable 10440 battery via an integrated USB-C port.
Streamlight 66608 MicroStream Output & Specs (pulled from website):
- High and low modes (double bump the tail switch to change modes):
- High: 250 lumens; 68m beam; runs 1.5 hours
- Low: 50 lumens; 31m beam; runs 3.5 hours
- Beam Distance68 meters
- Max Candela1,150
- Battery Type Lithium Ion Cell Pack
- Battery Quantity1
- Length3.87 inches (9.83 centimeters)
- Weight1.20 ounces (34.02 grams)
- Colors Coyote, Blue, Red, Black
I use these lights daily and always have one in my pocket. I got my first from a GLOCK Armorers course probably 10 years ago which was the original Streamlight Microstream and have always been looking for the same form factor with more lumens. Around 4 or 5 years ago Streamlight came out with the 66608 250 lumen model that has been the gold standard of Micro Lights since.
So now Cloud Defensive comes along to compete with the Streamlight in the Microlight universe. I picked one up with the promise of 350 lumens hoping for the next evolution in Microlights. I purchased the light directly from Cloud Defensive a month or two back. I’m not going to do a crazy review showing you spill in dark environments. Its just not worth it as this light is not worth my time and probably not worth yours. So let’s just hit the big points.
