Trigger Adjustment Pins TRIGGER ADJUSTMENT PINS The enclosed pins are meant to replace the hammer pin and sear pin in the side of the handgun so the relationship between the sear and the sear notch can be adjusted easily and precisely. Guns that do not have the hammer and sear pin holes drilled perfectly parallel do not present a problem. The final adjustment can be made outside the gun and will not change when the parts are reinstalled as sometimes happens with conventional, bench-type test blocks. Because of the large number of guns on the market, tolerances are designed for the best possible fit in the majority of guns. m WARNING m Never attempt to disassemble or reassemble a firearm unless you are absolutely certain that it is empty and unloaded. Visually inspect the chamber, the magazine and firing mechanism to be absolutely certain that no ammunition remains in the firearm. Disassembly and reas- sembly should follow the manufacturer’s instructions. If such instruc- READ & FOLLOW THESE tions are not immediately available, contact the manufacturer to see if they are available.

HOW TO USE COLT Gold Cup, Commander and Government Model Pistols: First re- move the magazine and slide assembly from the frame. Next, remove the mainspring housing, safety, grip safety, sear safety spring, hammer, sear and disconnector. It is not necessary to remove the grip panels unless desired for other reasons. COLT Single Action Army and New Frontier (including .22 cal.), RUGER Single Six, Super Single Six and Bearcat: The revolver is first stripped of the trigger and hammer. The trigger adjustment pins are inserted and snugged down on the left side of the revolver frame where the hammer and trigger screws go. The hammer and trigger are now placed on the pins. They are spaced in the same relationship that exists in the gun. Sear and sear notch engagement may be observed and adjusted as required. Enough thumb pres- sure may be applied to the hammer spur to simulate mainspring pressure in order to check the engagement and/or adjustments. RUGER New Model Blackhawk, Vaquero, Bisley, Super Blackhawk, Single Six, Super Single Six and Mk I/II Autos: Follow the manufacturer’s instructions for disassembly of the trigger and hammer. Push trigger adjust- SAVE THESE INSTRUCTIONS IN YOUR THESE INSTRUCTIONS IN SAVE ment pins into the pin holes of the trigger and hammer on the right side of the frame. The trigger and hammer are placed on the short section of the trigger adjustment pins. The trigger sear and hammer sear notch are now in the same relationship as they are in the gun and may be observed or adjusted as required. Enough thumb pressure may be applied to the ham- mer spur to simulate mainspring pressure in order to check engagement and/or adjustments. Reassemble the firearm according to the manufacturer’s instructions. Check for proper functioning using ACTION PROVING DUMMIES. Make sure ALL SAFETY MECHANISMS are fully functional as designed and approved by the manufacturer. If these tests prove satisfactory, test-fire the firearm with live ammunition in a SAFE and APPROPRIATE manner. IMPORTANT! Start the live ammunition tests by first loading an ACTION PROVING DUMMY, then a live round, into the magazine. Only after sev- eral tests have been conducted in this manner should additional rounds be placed in the magazine and fired. 076-200-302 R107 © 2007 BROWNELLS, INC. MADE IN U.S.A..

  • Firing Process of an AR-15 Firearm Platform
    Firing Process of an AR-15 Firearm Platform Introduction of the AR-15 One of the most universal firearm systems ever created is the AR-15 platform. The AR-15 platform is a semi-automatic firearm based on the design of Eugene Stoner’s original AR-10 produced by ArmaLite in the late 1950s. In 1959, the AR-10 was converted from using a 7.62x51mm cartridge to the much smaller 5.56x45mm cartridge and the AR-15 was born. The AR is actually a shortened designation for ArmaLite, the firearm manufacturer which originally designed the firearm. The M-16 used by the United States military is based almost entirely on the AR-15 design. The construction of the AR-15 is mostly aluminum and many different manufactures have a version of their own with many of their parts being compatible with others. The firing process is how a firearm is shot, sending a projectile down range to the designated target.A Colt brand AR-15 is displayed in Figure 1. Figure 1: Colt AR-15 Hammer Pulling the Trigger Sear Trigger Assembly: 1. Trigger 2. Sear 3. Hammer Sear/Hammer Catches 4. Sear/Hammer Catches Trigger Figure 2: Trigger Assembly Every firearm has a safety with at least a fire position and a safety position where the gun cannot be fired. Once the safety is changed to the fire position it is ready to be shot. To fire the gun the trigger must be pulled. When cocked, the front sear catches the hammer and holds it in place. One the trigger is pulled the sear slides out of the way of the catch on hammer, releasing the hammer.

  • Brownells Benchtalk
    2½ lb. Trigger Pull by: Jack Weigand Early in my career as a pistolsmith, I worked hard to develop a process I could apply to all 1911 Auto Pistols that would produce a reliable 2½ pound trigger pull that broke clean and would not follow. After a lot of trial and error and experimentation, I came up with the following process that has served me very well over the years. It’s the same process I now use during the Trigger Work portion of the NRA 1911 Auto Accurizing class that I teach each May at Montgomery Community College in Troy, North Carolina. It seemed many of my customers that shot in the U.S.P.S.A. sanctioned matches wanted a very light trigger pull, usually around 2½ pounds. Using this method you can get trigger pulls that are lighter than 2½ pounds, but very few shooters really know how to properly use a trigger pull that light and I think it can get them into trouble. Handguns that I build for carry, duty or defensive work have a 4 to 4½ pound pull weight. What is most important with any trigger job is that you have a minimum of takeup, very little creep, so it breaks clean and no overtravel. Using the methods I’ve outlined here, you will be able to consistently produce trigger jobs that meet all those requirements. One word about tools and replacement parts. I’ve included all of the tools that I use in my shop, but not the names of the individual components that I use.

    APPENDIX B RULINGS AND ATF ARTICLES 27 CFR 479.11232: MEANING OF TERMS The AR15 auto sear is a machine gun as defined by 26 U.S.C. 5845(b) ATF Rul. 81-4 The Bureau of Alcohol, Tobacco and Firearms has examined an auto sear known by the various trade names including “AR15 Auto Sear,” “Drop In Auto Sear,” and “Auto Sear II,” which consists of a sear mounting body, sear, return spring, and pivot pin. The Bureau finds that the single addition of this auto sear to certain AR15 type semiautomatic rifles, manufactured with M16 internal components already installed, will convert such rifles into machine guns. The National Firearms Act, 26 U.S.C. 5845(b) defines “machine gun” to include any combination of parts designed and intended for use in converting a weapon to shoot automatically more than one shot, without manual reloading, by a single function of the trigger. Held: The auto sear known by various trade names including “AR15 Auto Sear,” “Drop In Auto Sear,” and “Auto Sear II,” is a combination of parts designed and intended for use in converting a weapon to shoot automatically more than one shot, without manual reloading, by a single function of the trigger. Consequently, the auto sear is a machine gun as defined by 26 U.S.C. 5845(b). With respect to the machine gun classification of the auto sear under the National Firearms Act, pursuant to 26 U.S.C. 7805(b), this ruling will not be applied to auto sears manufactured before November 1, 1981.

  • KP 31 Fire Control Group Timing
    KP 31 Fire Control Group The Finnish KP 31 trigger pack is one of the best SMG fire control mechanisms ever made. It is durable, reliable, and has a smooth trigger pull that rivals most high precision rifles. Designed in 1930 by AJ Lahti, it features SAFE-SEMI-FULL AUTO selector at the front of the trigger guard. Fully forward is FULL AUTO, one click rearward is SEMI, and fully sear rearward is SAFE. The components disconnector are precisely machined from the high disconnector spring quality steel Finland is known for. Later SMG designs during and after trigger WW2 used less expensive methods better suited for mass production. The design and manufacturing paradigm when this was invented in 1930 was: sear spring ‘How good can we make this?’ By selector retaining the late 1930’s, the paradigm shifted detent selector bar to: ‘How fast can we make this?’ While the KP31 trigger pack quality and performance were battle proven during the Winter War, less expensive designs were better suited for their quantity needs. Sear Timing Set Screw: This is only used if the disconnector fails to reengage Timing the sear in semi-auto when the Trigger Pack Set Screw (described below) is already tight. In most lower housings this 8-32 set screw is not necessary or present. Tighten this set screw 1/2 turn at a time to push the sear down until the disconnector easily reconnects with sear after each trigger pull in semi auto. After reassembly, check for proper bolt sear function before using. Trigger Pack Set Screw: This is loosened to remove the trigger pack and tightened to keep the trigger pack firmly in the upmost position when assembled.
