Sunday GunDay: AR15 Uncovered — X-Ray Views of Black Rifles

Due to the COVID-19 Pandemic, many of our readers are dusting off their AR-platform rifles. Because ARs have a somewhat unique (and dirty) semi-auto operating system, we think all AR owners should learn how their rifles operate — from the inside out. This Sunday GunDay feature provides an “inside look” at the AR, with X-Ray and Cutaway views created through advanced 3D computer modeling.

AR15 Functions Revealed with 3D Computer Animation

Ever wondered how the parts inside an AR15 work together? Just exactly how does the reciprocating bolt carrier feed rounds from the magazine? How do the elements in the trigger group work and reset after each shot? How does the gas system bleed gas from the barrel and operate the bolt carrier? These and other questions are answered in this eye-opening video from 45Snipers. Using “cutaway” 3D computer animation, this 5-minute video shows all features of an AR15 inside and out. This fascinating firearms animation allows the viewer to look inside the upper and lower receivers, into the bolt carrier, chamber, barrel, and magazine.

This video starts off slow and has annoying background music, but it is well worth watching if you own or shoot any AR-platform rifle. It illustrates all the key operations during the charging, loading, firing, and ejection processes. The cutaway animation shows how rounds are stripped from the magazine and then chambered. It then shows how every part of the trigger group works, and how the firing pin strikes the primer. You can even watch the bullet move down the barrel before the empty shell casing is removed from the chamber and tossed out the ejection port. Here are sample frames from the video:

How AR-Platform Rifles Work — General Introduction
To help reader understand the general operation of AR-type rifles, this video shows the control functions of an AR and how the upper and lower sections work together.

Here is an excellent “cutaway” animation by Thomas Schwenke that shows how an AR-15 functions — how the entire loading cycle works from start to finish.

AR platform rifles are semi-automatics version of the M16. These feature distinctive upper and lower receivers which can be readily separated via front and rear pins. The upper includes the barrel, handguard, forward gas tube, and bolt assembly, while the lower contains grip, trigger group, fire selector, and mag well. In addition the lower is attached to the stock which encloses the buffer assembly.

The original ArmaLite AR-15 was a select-fire, air-cooled, gas-operated, magazine-fed rifle designed by American gun manufacturer ArmaLite in 1956. It was based on Armalite’s AR-10 rifle chambered for the 7.62×51 NATO (.308 Win). In 1959, ArmaLite sold its rights to the AR-10 and AR-15 to Colt. Some key modifications were made — most notably, the charging handle was re-located from under the carrying handle to the rear of the receiver. The redesigned rifle was adopted by the U.S. military as the M16 carbine, which went into production in March 1964.

DHS States Gun-Makers and Retailers Are “Essential Businesses”

Department homeland security Dhs gun retailers firearms order Coronavirus essential business

Story based on 3/28/20 report by Ammoland.com.
The Department of Homeland Security has declared firearms manufacturers and retailers “essential businesses”. This is very important because many states, including California and New York, have issued Executive Orders which have shuttered gun stores and halted the operations of FFLs. The DHS statement should, hopefully, lead to changes in state and regional emergency orders requiring gun shops to close.

The reference to gun retailers and gun ranges is found in a DHS document titled Guidance on the Essential Critical Infrastructure Workforce in the section dealing with “Law Enforcement, Public Safety, and Other First Responders”.

Legal Actions to Counter Closures of Retail Gun Stores and FFLs

On Friday, 3/28/20, the Second Amendment Foundation (SAF) and the Firearms Policy Coalition (FPC) joined forces with the NRA, California Gun Rights Foundation and several others in a federal lawsuit against Gov. Gavin Newsom and Los Angeles County Sheriff Alex Villanueva. They are also alleged to be using the COVID-19 pandemic to close down gun stores.

Comment: In California, all the gun shops have closed, yet Marijuana Dispensaries and Vape Shops remain open as “essential businesses”. That shows you Gov. Newsom’s priorities — recreational drugs are good, while guns are bad. The California Governor is exploiting this crisis to harm the gun industry and put gunshop owners out of business. And in Washington state, Gov. Jay Inslee’s emergency order listed employees at marijuana shops, breweries and winemaking facilities as part of the essential workforce, but omitted firearm and ammunition retailers and distributors.

The same day (3/28/20) in North Carolina, SAF and FPC filed a federal lawsuit against Wake County Sheriff Gerald M. Baker for refusing to accept new applications for pistol purchase permits or concealed handgun permits until April 30, 2020, using the COVID-19 outbreak as justification.

Previously, the SAF filed a lawsuit challenging New Jersey Governor Phil Murphy’s order shutting down firearms dealers. In Kashinsky v. Murphy, the SAF is joined by the New Jersey Second Amendment Society in alleging violation of “civil rights under color of law” by shutting down firearms dealerships, preventing citizens and businesses from exercising their rights under the Second and Fourteenth Amendments.


This story is based on an article created by Dave Workman for Ammoland.com, which states: “Readers, please share this article with your state, local and federal representatives, police departments and sheriffs as well local firearms retailers to make them aware of the new guidance so we can get our local business back to work and fellow Americans the products they need to remain safe.

See Bullet Holes at 500+ with White Background Splatter Targets

shoot-n-c sight-in-target white black halo

Do you have trouble seeing your bullet holes (on paper) when shooting past 400 yards? That’s a common issue even with premium ($1600+) high-magnification scopes. Here’s a target that solves that problem. A hit creates a larger black circle that’s much more visible than a plain bullet hole, making this target ideal for use at longer range (500 yards and beyond).

The 12″ square Birchwood Casey white background Sight-In Target displays a black “halo” around each hit (like the yellow circle on a conventional Shoot-N-C). Larger than bullet diameter, the “halos” can be easily seen with a high-magnification scope at long range (see video below). The self-adhesive target features four diamonds with contrasting red box centers. For precise aiming, you can position your cross-hairs to align with the corners of the boxes. Or, you can put a target dot sticker in the middle.

This video shows Black Shot Halos on white background:

White splatter targetWhile we envision using this target with optics at long range, Birchwood Casey says that open sights show up well against the white background, making these targets well-suited for indoor ranges or use in low light conditions.

This white background grid target has five aiming points and a 1-inch grid overlay for quick and easy sight adjustments. It comes with target pasters that allow shooters to cover up bullet holes and continue using the target for added value. The White/Black Shoot-N-C 12″ Sight-In Targets come in 5-packs with 75 target pasters for $8.99 from MidwayUSA or $12.70 on Amazon. If you prefer circle targets, there is a larger 17.5″ Shoot-N-C target with one large bull with red diamond center (photo right).

High-Viz Option — Yellow on Black Grid with Yellow Halos

If you prefer seeing ultra-high-contrast yellow/green “halos” for your hits, Birchwood Casey also makes adhesive grid targets with five yellow-edged diamonds. Red circles provide precise aiming points in the middle of each box. You can quickly estimate group size or dial-in your zero using the hi-viz yellow 1″ grid lines. These yellow-on-black targets are available in three sizes: 8″ square, 12″ square, and 17.5″ square. These yellow-on-black grid targets start at $6.80 for an 8″ five-pack.
