Molded rail sections. From L: Scout light adapter, long and short Picatinny rails.
I have been using the CMR rail from Centurion Arms for a while on my latest rifle build. It is an exquisitely well executed tubular forend with a 12:00 rail and threaded helicoils for the attachment of modular rail sections. My buddy Monty from Centurion had supplied me with a set of the preproduction rail sections a few months ago, and I finally got around to getting them onto the gun. The rail sections are molded, and screw right onto the tube via the threaded helicoils. As pictured above, there is a Scout mount adapter as well as a long and short Picatinny rail. Other adapters, including an X300 mount, are in the works. Production units of the pictured rail sections should be hitting fairly soon at your favorite Centurion dealer. Continue reading
87 Industries Gas Block Kit comes complete with the gas block, set screw, cross pin, gas tube pin, and hex wrench.
Our dedicated followers know that a pinned gas block is cheap insurance that your gas system won’t leak or come apart at the worst possible moment. Popular extended hand guard systems don’t make it easy to check if your set screws or gas block is loose, and a cross pin is the most reliable way to ensure your gas block is snug. However, for end users that don’t have access to custom fixturing or a mill, pinning a gas block on your own build can be a hassle. Enter 87 Industries.
They offer a Pinned Gas Block Kit which is set up so that the end user can install a pinned gas block with nothing more than a vise and a drill press. The owner tells me that it can even be done with a steady hand and a hand drill in a pinch. The kit includes a drill bit, tapered cross pin that eliminates the need for reaming, Loctite 262, set screw to hold the block in place during drilling, and allen head wrench. The gas block is made of very tough 17-4 Stainless finished with black oxide. The block works with .750″ diameter barrels.
I will be installing one of these with a drill press on a future build, so stay tuned.
I recently completed a stripped Gen 2 Noveske Chainsaw Grade lower and topped it off with a BCM mid-length upper with a Centurion Arms rail. For my optic I chose both a Trijicon ACOG (the compact 1.5 X 16S, see here) or a short base EOTech (see here). A good looking, well set up AR with optics, Made In The USA! For white light, I mounted a Surefire X300 Ultra. Fits and looks good, and is lightweight . . . I even like the way the activation switches work, except for one issue, see below. (Prior Jerry Jones MSW post about the Surefire is here).
My GAP built Surgeon actioned 6 Creedmore with Vortex Razor 5-20 scope
The amazing thing about the firearms industry currently is the vast array of options a person has to modify his/her weapon to their tastes or preferences. This variety is not limited to the adult Lego® of the firearms world, the AR15. There is now also a great market of accessories and options for precision bolt action rifles that’s growing rapidly. The biggest mistake I see many new shooters make with their first bolt action rifle purchase is making the assumption that all rifle stocks or chassis will fit everyone. This is sadly not the case. Each individual shooter’s length of pull, cheek structure, hand size, forearm length, and a number of other factors play into each shooter’s fit to a stock. There is always someone more than willing to tell any new shooter that the stock or chassis that they have is the only way to go. More often than not I watch online as shooters go from a stock to a chassis and back, continuously buying and selling stocks until they finally settle on one that is comfortable for them and fits their shooting style.

A properly managed sling eliminates snag hazards in confined spaces.
If you have ever deployed a long gun from inside a vehicle, you’ve probably figured out that the sling is quite the headache. It’ll get wrapped around your legs, the steering column, the shifter, seat belts, the list goes on. It is a simple matter to manage the sling with a bungee cord wrapped around your stock. I have seen folks use masking tape or rubber bands to allow a quick tear away option, but the addition of about 8″ of shock cord from Supply Captain provides a permanent solution that is always with your rifle.

I had the distinct pleasure of traveling to the Way Of The Gun training facility recently to train with Frank Proctor. Frank operates his facility out of Eastaboga, Alabama, which is near Talladega, Alabama for those of you that follow racing. Frank’s facility is still pretty spartan, as it appears that construction and additions are a daily event. But, the layout is pretty ingenious as he offers a training area and a public range area to the local community. Frank is going to have a world class training facility. Continue reading
After receiving my new CMR rails from Centurion Arms, I was dying to run the new tube on something. I had a few parts lying around from Palmetto State Armory – a 16″ M4 profile upper and a complete bolt group – so it seemed like they were all meant to go together. Continue reading
Remington 700 in 300wm in an Accuracy International chassis with Viper skins.
Accuracy International is one of the premier military hard use rifle manufacturers in the world. Known for making no nonsense, purpose built weapons and chassis for bolt action rifles, their AI Arctic Warfare (AW) and AI chassis system shape is one of the distinguishable shapes in the firearms industry. With its square fore end, folding option, and wealth of adjustments its a very capable Mil/LEO bolt-in option for the R700 platform. With that being said their thumb hole design fits some shooters more then others, leaving some to shy away from the design. This is where Michael Victor came in with his design for the Viper Skins in 2010. Victor Company’s Viper skins are replacement skins/ stock sides for the AIAW/ AIAE and AI chassis systems replacing the thumbhole with a pistol grip. Other added features to the viper skins are a widened fore end and integrating picatinny rails for additional accessories. Continue reading
A little painting going on in the Jones household this week. The top rifle is new and was in need of a coat of paint. The bottom rifle was painted seven or eight years ago and I grew tired of the pattern. The old pattern had a Field Drab base with Marine Corps Green and Black.
Both rifles were properly degreased and base coated with Aervoe 977- Sand. The bottom rifle was then painted with Aervoe 992- Marine Corps Green to see if I liked the color. It was a bit dark for what I wanted, so I painted the top rifle with Aervoe 979- Forest Green. Both rifles were then finished with Aervoe 999 Earth Brown. The optic on the top rifle is a temporary Aimpoint on it. When the new Aimpoint comes in, I’ll get it painted as well.
Over the past few years, Centurion Arms has earned the reputation of producing premium quality parts and accessories for the M4 platform. My first introduction to their product line was through their excellent C4 HK-style diopter sights. These sights resemble those found on HK rifles and sub-machine guns, but incorporated features for the sophisticated shooter, such as same plane diopter sights, lightening cuts, and slotted screw heads instead of silly Philips heads.
Since then, Centurion has added premium DMR uppers as well as the innovative C4 and CMR free float hand guards. Recently, there has been a shortage of bolt groups in the market. Centurion has responded by offering magnetic particle inspected, bolts. The carriers are full M16 profile, chrome lined, with well staked gas keys.
They are available now through select dealers.
Lately it seems to have become very popular for the internet commando community to bag on the so called “C Clamp” grip. So many top instructors and shooters use a variation of this support hand position that it would seem they must all be wrong. It is very difficult to discard the mechanical advantages of this grip, which places the shooter’s hand high relative to the bore line. The above photo shows one of the more common interpretations of the grip, with the support hand placed forward on the forend, and the thumb rolled over the top.
Don’t throw the baby out with the bathwater people, the support hand position is only one part of the shooting stance. We will explore the nuances of different support hand positions in an upcoming article.
The MagPul MBUS front and rear sights are inexpensive and functional for almost all purposes.
There was a time when optics were not nearly as dependable as they are today. Nowadays, non-magnified sights such as the Aimpoint Comp M3, M4 and T-1 have battery lives more easily measured in years than hours. The durability of modern optics have also improved to the point where in hundreds of thousands of rounds fired downrange, I have yet to see an Aimpoint fail (though I have heard of it from trusted sources.) But, that does go to show that even though it happens, it is a fairly rare event. I have seen iron sights get damaged or knocked out of adjustment more often than an Aimpoint lose zero or stop working.
So, do back-up iron sights (BUIS) still have a place on your carbine? Over the past decade, despite the tedious process of zeroing the RDS and backup irons, I have yet to need to deploy them. Not to say I will never need them, but with the cost of many quality sights sets exceeding $200, outfitting every training gun I build can get expensive. I have had great success with the MagPul MBUS sights. They hold zero inside of 100 yards, and for a CQB gun they are an excellent choice. For a dedicated range gun, I may just go without the BUIS.
The point is this: examine the purpose for which the gun you are setting up, and don’t just accessorize based on what your friends on Facebook tell you. If you’re building a precision or 7.62 caliber rifle for extended ranges, perhaps a set of quality iron sights like the offset Knights or Troy Industries flip ups will be worth the additional cost. For most purposes, the Magpul MBUS is the most economical and functional solution. And don’t feel bad not running one at all on a range-only gun unless you have a specific training purpose for it.
A common and popular modification to M4/AR15 platform these days is to install a narrow diameter tube style free-float rail (or any other long rail) system to replace the stock hand guards. If you are buying a new upper receiver, it is fairly simple to specify a low profile gas block. However, if you are starting with a service grade carbine like the excellent Colt 6920, you are going to have a standard A-frame type front sight base. What to do? Continue reading
Who doesn’t love the smell of gunpowder in the morning?
Are you a law enforcement officer, military service member, hunter, or just a casual shooter who is interested in increasing their ability to hit targets at distances greater then 200 meters? Now, what if I told you, you could do this with a great group of people in a fun, safe environment, on some of the best ranges in the country, and have the chance to take home a prize? Interested now?
Well, let me introduce you to the world of tactical precision rifle matches. Unlike F-class or other precision rifle disciplines in tactical precision rifle matches, you will engage targets at varying distances from positions outside of only prone or off a bench, while wearing your needed gear, most times while under both a clock and physical stress. Modeled after many law enforcement and military sniper competitions, it gives civilians the opportunity to safely test their skills against one another in varying scenarios across the country. It is fairly inexpensive to take part in and welcomes young and old, male and female, sponsored and amateur shooters shoot side by side in this quickly growing sport. Continue reading
I recently swapped out my old truck for a new model. Nothing all that exciting there except that I have had to re-fit all of my weapons and equipment in the new truck. One thing that always drove me crazy about the old truck was the way I mounted my AR style rifle. I had it in a roof rack over the back seat. It was out of the way and secure, but nearly impossible to grab in an emergency. It also stood out like a red dress at a funeral if you looked into the cab of the truck. Because of this I opted to find a more suitable solution for what is, for me personally, required equipment in my truck. Remember, it is not paranoid, it is prepared.
The Liberator easily fits my 16″ AR style rifle with Aimpoint red dot and Surefire X300 Ultra.
