Thomas Colyer Wins Leech Cup Shoot-Off
Forum member Corbin Shell reported: “I was fortunate to score for Thomas Colyer who shoots on the Oak Ridge Sportsmen’s Association (ORSA) long range rifle team. His Shoot-Off score was a 100-5X — not dropping a point. Michelle Gallagher was also in the Leech Shoot off and shot 99-3X.” A talented marksman, Thomas Colyer also won the Wimbledon Cup several years ago.

Palma Competition — by John Parker, Shooting Sports USA

According to the NRA High Power Rules 3.3.1 (a), a Palma rifle is “a rifle with metallic sights chambered for the .308/7.62 or .223/5.56 NATO cartridge case”.

When talking about Palma rifle competition, the traditional course of fire is at three yardages, 800, 900 and 1000 yards. The first Palma match was conducted by the NRA in 1875 at New York’s Creedmoor Range. The original Palma trophy, now lost to the ages, was commissioned by none other than Tiffanys.

3D Cutaway Animations Reveal How AR15 Rifles Work

ar-15 AR15 3D animation video youtube cutaway 5.56 AR .233 Rem

Americans love AR-platform rifles. However, they can be maintenance-intensive, as hot gasses are directed right back into the action to operate the bolt. 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 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.

Cutaway 3D Animation of AR15/M16 Action — Watch Video

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.
