Gas piston performance keeps this carbine cool and clean!
The Core15 M4 Piston offers LEOs a clean-running patrol carbine for duty use on the streets.
The Core15 M4 Piston 5.56mm combines M4-style handling with a cool-running gas piston system of operation. Shown equipped with a Norton Performance 1-6×24mm CRS scope and a Dueck Defense Rapid Transition offset iron sight system.
It’s hard to keep track of all the companies that build AR-15-type rifles these days. At some point in the recent past, I was visiting with someone in the gun industry and we determined that the number of AR manufacturers hovered around 75 companies. My list isn’t quite that long, but it’s close. As a result, a law enforcement officer has a dizzying array of choices when it comes to selecting an AR-based tactical carbine.
The piston system of the Core15 features a two-position regulator and theoretically runs cleaner and cooler than standard ARs.
With all of these companies in the AR business, it gets rather murky telling the difference between a gun made by Company X or Company Y. Since last summer, and by the time this issue goes to press, I will have tested 47 different ARs made by 27 different companies for this and other Harris magazines. From a distance, many of these rifles look basically the same. Even a close inspection of their operating systems makes distinction between guns difficult. At this point, you have to learn something about the people at each company to find the nuances in manufacturing that set one company’s product apart from another’s.
When I got the assignment to test and evaluate the gas piston AR made by Core15, I was surprised to find Israel “Izzy” Anzaldua at the helm. If you know Anzaldua by name, you’re probably familiar with Bushmaster. He was the director of global training and technical services for that company, but aside from a title too long to fit on a business card, Anzaldua helped create the .450 Bushmaster and the company’s Predator rifle, and created the company’s Varminter rifle. Ironically, my introduction to ARs was when I purchased a Varminter several years ago. Prior to his 22 years at Bushmaster, Anzaldua spent 10 years active in the Army as a weapons specialist (and 12 years reserve). “I was 14 years old and in the ROTC was the first time I picked up an M16,” Anzaldua was quick to add. Upon leaving Bushmaster, Anzaldua moved to the upstart Core15 Rifle Systems, which benefited from his new role as vice president of sales and business development.
The gas block offers a section of Picatinny rail for mounting a front sight and the 16” barrel features an M203-style step down cut.

Taurus PT 24/7 G2
私たちのブログを訪問していただきありがとうございます。あなたがお持ちの場合DIYの要求は私達に電子メールを送信してください。
Taurus is a company that just keeps on expanding their product line. Not only do they release new models on a regular basis but upgrade established models to keep up with current trends. The Taurus 24/7 G2 is one such pistol.
The G2 has been out now for almost a year and from what I’ve read and experienced has been well accepted as a full size defense pistol. The G2 comes in a hard plastic case with three interchangeable backstraps, two thirteen round magazines (40 cal), cleaning brush and two keys for the internal safety lock. A magazine loader is also included in the package.
I know some shooters like guns with a minimalist approach to pistols such as the Glock however I prefer a manual safety. The G2 not only has a manual safety much like a 1911 in operation but in placement as well. For a 1911 guy like myself this is a welcome addition. The G2 also has a complete set of controls which are all ambidextrous. The slide release, manual safety with a dual function as a striker de-cocker, magazine release all are mirrored on the right side. This is especially beneficial for lefty shooters as well as those who should be practicing left handed.
This two tone stainless and black G2 is the standard model which is designated by the DA/SA DS stamped on the slide. The first round fired is double action will all others single action. The DS stands for double strike which most will recognize as the ability to pull the trigger twice on the same round should the round fail to fire. This feature has little interest for me but I’m sure others will appreciate it since the second strike usually fires the round.
The trigger is much like the Glock in appearance as well as safety function. Takedown is identical to a Glock with the two tabs on either side of the slide which are pulled down allowing you to remove the slide. The rear of the slide has an industry standard striker status pin. The top of the slide at the rear of the barrel has a triangular shaped steel piece which is a loaded chamber indicator. This way the shooter can see and feel the loaded status of the pistol.
One other feature to note with the manual thumb safety is depressing the safety all the way down de-cocks the striker. The frame also has a rail for an aftermarket light or laser combination.
The rear sight is especially nice since it is a very low profile sight adjustable for windage and elevation. There are two screws on the right side of the sight for windage adjustment with a center screw on top for elevation adjustment. The backstraps are changed by tapping a pin out at the rear base of the grip.
The trigger on the G2 is smooth but does stack a bit at the end of the pull. The trigger pull is also a bit longer than I would prefer. However the trigger issue isn’t a deal breaker. It’s just not that bad. I’m just a bit picky about such things. The frame also has a rail for an aftermarket light or laser combination.

Zeiss ZO 4x30i Combat Gunsight
私たちのブログを訪問していただきありがとうございます。あなたがお持ちの場合DIYの要求は私達に電子メールを送信してください。
At 2012, he Hensoldt division of Zeiss released the Zeiss ZO 4x30i combat gunsight. The new sight, specifically designed as a combat optic for small arms, has a fixed 4x magnification, is robustly built and offers a very wide field of view. This puts it in the same category as the popular Trijicon ACOG series.
The new combat gunsight is based on the Zeiss ZO 4x30 that is in service with the German military aka the German Bundeswehr. While neither the German military nor Zeiss likes to admit it, the ZO 4x30 had been combat tested in peacekeeping missions and the NATO operations in Afghanistan. Zeiss originally developed the ZO 4x30 as the replacement optic sight for the Bundeswehr’s Heckler & Koch G36 assault rifle’s build-in ZF 3x4° sight.
The Zeiss ZO 4x30i retained the same proven optical formula as the Bundeswehr’s ZO 4x30. It features a 30mm objective lens with a fixed 4-power magnification. The ocular lens size is very large at about 35mm, which gives a big and highly detailed sight picture. The exit pupil is 7.5mm and that is bit larger than the average 5-6mm offered by most of the riflescopes. The eye relief is comfortably at 2.56 inch or 65mm. The internal adjustment system offers 20 mils of adjustments on both the vertical and horizontal axis. Each click of the turrets is 0.2 mil of adjustment.
The biggest improvement over the old build-in ZF sight is doubling the field of view (FOV) from 4 degrees to 8 degrees on the ZO 4x30/4x30i. That had practically increased the viewing area by 10 times through the optic. 8 degree FOV covers 42 feet at 100 yards.
The “i” suffix in new Zeiss ZO 4x30i version stands for illumination. That was added because the German military didn’t want in illuminated reticle for the original version. The newly added illumination system is powered by a single AA battery. Interestingly, the ZO 4x30i’s illumination system is capable of regulating the battery voltage from 1.2 volt (rechargeable AA battery) to 3.6 volt (industrial lithium cells in AA size). The battery life is rated for 800 to 1200 hours per AA battery. There are 6 daylight illumination levels and 3 dedicated night-vision settings.
