Primary Weapons Ratcheting Castle Nut and End Plate: No More Staking

The Primary Weapons Systems Ratchet Lock Castle Nut and End Plate Set allows the armorer to attach either commercial type or Mil-Spec Buffer Tube to your AR-10 &and AR-15 based weapon without the pain-in-the-neck of staking. Yes, it’s secure, and guess what PWS created this option considering the possibility that you might want or need to change a buffer tube before your weapon deadline. You’re not married to the installation, and it won’t require you to destroy anything to get it apart. You might even do it without any colorful language.

The endplate includes an integrated QD mounting point for your sling swivel so you can get hooked up and get on with it. Is it a huge thing? That depends on how badly you need it today. Is it evolution? Definitely. Why do we need it? Because It’s Time, we stop suffering over the small stuff and evolve.

What is Ferritic Nitrocarburizing (FNC)

Ferritic Nitrocarburizing (FNC) imparts high surface hardness, improved wear resistance and fatigue resistance to a wide variety of carbon steel, alloy steel and cast iron parts. Because the process is carried out at temperatures below 1100 F, retention of core properties and good dimensional control are achieved. In many applications, FNC treatment also improves corrosion resistance through the formation of a continuous compound layer on the work-piece surface which can allow for the elimination of subsequent protective plating operations or application of rust preventive.

Improve surface hardness and wear resistance with ferritic nitrocarburizing

The surface compound layer formed by FNC treatment is an epsilon iron-nitride compound and this layer may range in depth from .0002″ to .0010″ inch depending upon cycle parameters selected and base material being treated. FNC compound layer hardness values will typically range from 55 to 65 HRC depending on the base material being treated. Higher alloy steels with nitride forming elements (Cr, Mo, Ti, W, and Al) will have higher hardness compound layers than plain carbon and low alloy steels and will also benefit from the formation of an underlying higher hardness diffusion zone below the compound layer that gives improved fatigue life and helps to support the surface compound layer.

Ferritic Nitrocarburizing is often selected to replace chrome plating due to environmental concerns with plating. FNC also has been used to as an alternative process to solve problems with size change and distortion associated with higher temperature treatments like carburizing or carbonitriding.

Geissele Super Semi-Automatic Enhanced SSA-E Trigger

Improving over the Geissele SSA two-stage combat trigger is the Geissele Super Semi-Automatic-Enhanced (SSA-E). The Geissele SSA-E offers an even lighter, 3½ lb. total pull weight, making it an excellent choice for precision Squad Designated Marksman type rifles where both accuracy and reliability are critical. The first stage builds gradually to 2.3 lbs., followed by a 1.2 lb. second stage with a crisp, “candy cane-like” break. A semi-auto-only version of the Geissele full-auto combat trigger presently used in the U.S. Special Operations community.

GEISSELE SSA-E TRIGGER INSTALLATION INSTRUCTIONS

GEISSELE SUPER SEMI-AUTOMATIC (SSA-E®) TRIGGER INSTALLATION INSTRUCTIONS

READ THIS FIRST – Firearm safety is YOUR responsibility. You must memorize and put into practice the 4 Rules of Firearm Safety:

  1. ASSUME EVERY WEAPON IS LOADED.
  2. KEEP YOUR FINGER OFF THE TRIGGER UNTIL YOU ARE READY TO SHOOT.
  3. DO NOT LET THE MUZZLE POINT AT ANYTHING YOU ARE NOT WILLING TO DESTROY.
  4. KNOW YOUR TARGET AND WHAT IS BEYOND.
 

GEISSELE SSA-E TRIGGER INSTALLATION INSTRUCTIONS

  1. Unload rifle and make safe.
  2. Remove existing trigger and clean receiver. It is not necessary to remove the safety.
  3. Remove the trigger pin from the trigger and replace with the slave pin to hold the disconnector in place.
  4. Install trigger and slave pin into rifle. Align slave pin with receiver pin holes. Insert trigger pin into receiver, through trigger/disconnector, and into receiver on opposite side.
  5. Remove hammer pin from hammer. Place a drop of lubricant in the bore of the hammer pivot.
  6. Install hammer into receiver with hammer spring legs on top of the trigger pin. Insert hammer pin into receiver, through hammer, and into receiver on opposite side.
  7. Apply a small amount of lubricant in the following locations: a. Each side of the disconnector above the trigger pin b. Hammer and trigger sears c. Face of the disconnector d. Hammer tail where it contacts the disconnector; e. Top of each side of the hammer spring where the spring contacts the receiver wall.
  8. Check safety operation: With the hammer cocked and the safety selector set to the SAFE position, pull the trigger hard. The hammer should not fall.
  9. Check trigger reset: Set safety selector to FIRE. Dry fire weapon and keep trigger held back. Pull charging handle all the way  back and release, letting the bolt carrier snap forward. The hammer should not fall. Release trigger. Hammer should be caught by the trigger.
  10. Check for the presence of a second stage: Set the safety selector to FIRE. Pull the trigger through the first stage until it comes to a distinct stop—this is the second stage. Applying additional pressure to the trigger will allow the weapon to discharge. Maintenance of the SSA trigger consists of occasionally placing a drop of lubricant on the locations shown in #7 above. Recommended lubrcant is CLP or equivalent; alternatively a high quality grease may be used on the trigger/hammer sears and disconnector contact surfaces. When the trigger and lower receiver well become very dirty (such as when firing with a suppressor), it is not always necessary to remove the trigger group for cleaning. Spray down the trigger group with electrical contact cleaner to remove residual oil and dirt. Next, use compressed air to blow off the trigger group and then flush liberally with a light lubricant as CLP or equivalent. Blow off excess lubricant with compressed air and lubricate as noted above. The Geissele Super Semi-Automatic trigger is a 4.5 lb. non-adjustable precision combat trigger and allows precise and accurate trigger control. The SSA’s two-staged design allows the trigger to be light enough for accurate and precise shots, but heavy and forgiving enough to be safe. The SSA is safety certified by Crane Naval Surface Warfare Center. It is recommended for demanding applications such as Law Enforcement use, Close Quarters Battle (CQB) and mid-range carbine work. The SSA Trigger will lighten the trigger pull relative to a standard trigger. This lightened trigger pull will make the firearm easier to discharge. You must recognize and accept this fact before installing this trigger. If you do not want a lighter than standard trigger pull or are not willing to accept responsibility for the safety of your firearm, yourself, and those around you, do not install this trigger. Geissele Automatics recommends installation by a certified gunsmith only.

Geissele Super Semi-Automatic Enhanced SSA-E Trigger

Download – Geissele Super-Semi-Automatic SSA Trigger Sales Flyer

The Geissele Super Semi-Automatic Enhanced (SSA-E) Trigger is a finely-tuned semi-automatic-only version of our full-auto, two stage combat trigger presently used in the U.S. Special Operations Community. Built on the chassis of the Geissele SSA, the SSA-E provides enhanced trigger control and weapon accuracy while maintaining the robustness and reliability of our combat-proven two-stage trigger. The SSA-E’s reduced 1st and 2nd stage pull weights result in a trigger with a smooth, light 1st stage take-up and a crisp, candy cane-like 2nd stage break. The SSA-E is ideal for use in precision Squad Designated Marksman type rifles where weapon accuracy and reliability are critical and a non-adjustable drop in trigger is desired.

Performance Advantages for the Shooter

  • The Geissele SSA-E has a pull weight of about 3.5 lbs. There is 2.3 lbs. on the 1st stage and 1.2 lbs. on the 2nd stage. The pull weights and sear engagement are non adjustable by the shooter.
  • Trigger and hammer are made from quality tool steel.
  • Sear surfaces are cut by a wire edm machine. Sears cut this way are very accurate and the non-directional surface finish of the wire edm gives a smooth trigger pull without the associated grittiness of directional machining marks left by a milling cutter.
  • The initial force needed to start the disengagement of the searnsurfaces is low and the force linearly increases at a low rate. This helps the shot to fall at the initial point of aim and aids in building shooter confidence in his weapons ability to put the rounds where his sight is pointing.
  • The Geissele SSA-E trigger allows the shooter to slap through the trigger pull on close in shots but also set up a long range shot with a crisp trigger break.
  • A full force hammer spring is used for quick locktime and positive ignition of all types of ammo. There is no lightened hammer spring used.
  • The hammer is lighter than a standard AR15 hammer. The lightened hammer favorably decreases locktime over a standard hammer from 8.5 to 5.1 ms and increases accuracy of the weapon.

Advantages for the Armorer

  • The Geissele SSA-E is a simple design that is very similar to the original M16 trigger. The number of parts is identical.
  • There are no adjustment screws to come loose.
  • All springs are captive; they will not get lost during disassembly in the field.
  • The entire trigger can be disassembled for cleaning (no rivets or staked parts).
  • The trigger can be installed without removing the safety.
  • Sear engagement is pre-set from the factory.
  • Hammer and trigger pins are a close slip fit into nominal receiver holes so the trigger can be installed and removed with rudimentary tools.
  • Triggers come with a slave

Safety Advantages

  • The Geissele SSA-E is a 2 stage trigger where there is generous overlap of the sear surfaces which contributes to safety and a low tendency of any inadvertent movement of the trigger to discharge the weapon.
  • The Geissele SSA-E has a patented pseudo sear that is almost identical to the standard AR15 single stage sear. However, this secondary sear has surfaces that never touch during normal operation. This sear prevents the hammer from falling unless the trigger is pulled.
  • The secondary safety sear contributes to shooter confidence in dynamic/vehicle situations where a fellow shooter’s muzzle may cover him. There is firm knowledge that even with the safety in the fire position the weapon can never discharge unless the trigger is pulled.
  • Trigger timing is robust and parts have been sized to operate with a certain amount of wear to the working surfaces. The trigger is designed to operate in dusty, abrasive environments that cause wear.

*The Geissele SSA-E does not fit HK416 weapons with firing pin safety.

PMAG® D-50™ LR/SR GEN M3™

Magpul PMAG D-50 Product Details

The Magpul PMAG D-50 is a rugged, lightweight 50-round polymer drum magazine designed for 7.62×51 NATO/.308 Winchester ammunition for SR25/M110 pattern rifles. It’s capable of using longer-than-SAAMI-spec match ammunition, up to 2.830” OAL, such as M118LR. Engineered to the same exacting standards as the famous Magpul PMAG and PMAG D-60® drum magazines, the D-50 continues the PMAG tradition of high-capacity performance and dependability.

Durable and Reliable

The Magpul PMAG D-50 incorporates proven GEN M3 technology, which includes next-generation impact and crush-resistant polymer construction and the ability to seat fully loaded on a closed bolt. Robust stainless-steel internals withstand corrosion and long-term storage while loaded with no loss of function, spring fatigue, or reliability concerns. A slip-on semi-rigid dust cover prevents grit and debris intrusion during storage and transport.

Easy to Use

A ratcheting loading lever removes spring tension, making the D-50 easily loadable by hand. An anti-glare translucent window on the rear of the drum makes for quick positive visual indication of remaining ammunition. Additionally, the D-50 can be disassembled quickly with a simple flat blade screwdriver or similar tool and it comes with a dot matrix pattern that allows for easy marking and identification

Lightweight, Compact and Affordable

At approximately 1.7 lbs empty, and 4.5 lbs loaded, the Magpul D-50 is one of the lightest 50-round 7.62×51/.308 drums available, and it’s priced well below the current competition. The D-50’s unique drum configuration gives it roughly the same overall height profile as a standard 25-round PMAG, making storage easy and shooting from various positions–including prone–no different than with smaller capacity magazines.

Magpul PMAG D-50 Specifications

*Optimized for use only with 7.62×51 NATO/.308 Winchester cartridges.  Use with other calibers such as .260 Remington or 6.5 Creedmoor is not recommended.
