Power Drop-In Trigger from Hiperfire!

HIPERFIRE’s customer base has clamored for an AR drop-in trigger that features the “feel” and hard-hitting hammers its triggers are known for. Most aftermarket drop-ins are notorious for LPS, light primer strikes. To get the pull weight down, designers have compromised their hammer fall. Not so with the new PDI line of triggers.

Hiperfire PDI Drop-In Trigger

These drop-ins pull at around 2 lbs. and sport HIPERFIRE’s unique HIPERSHOE that now mounts onto a curved bow, not just straight. The hammer strikes surpass SAAMI’s copper crusher spec and hit harder than MIL-spec M4/16 hammers. Wow! The pull? It’s single stage. It’s short, sweet, and smooth as butter. The “feel” is almost transparent to the shooter. To top it all off, no PCC blowback violence can touch it. The PDI versions feature a hammer collision bumper. Its disconnector and disconnector spring are impact and crush protected. Is it just for PCC? No way. It’s just an excellent trigger. Anyone can appreciate it shooting slow, fast, short-range, or for long-range precision, and on the move, it surpasses SAAMI’s rough handling specification.

  • MIL-Grade Hammer Strike, No LPS, Ever

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. 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.

FOSTECH ECHO AR-II TRIGGER | DROP-IN TRIGGER

FOSTECH ECHO AR-II TRIGGER | DROP-IN TRIGGER

PICTURE of a FOSTECH ECHO AR-II TRIGGER

FOSTECH ECHO AR-II TRIGGER

Based on a Hiperfire trigger the Echo Trigger has a unique feature that allows an AR to fire when the trigger is pulled and also when released. This translate into much more expensive trips to the gun range. My two initial observations are the trigger is quite expensive and also looks to be pretty complex. At this time I cannot confirm how this trigger functions in a 308 AR or AR-10.  If anyone has any experience with the echo trigger drop us a line. The Fostech Echo AR-II Trigger is in stock and available from Brownells.

The Echo AR-II Trigger allows the shooter to select from 3 different settings.

Safe Mode: Firearm will not fire.
Semi-Automatic Mode: Firearm fires when trigger is pulled.
Echo Mode: Firearm fires when trigger is pulled and also when trigger is released.

The Echo AR-II Trigger is designed with safety being the utmost priority. When the shooter is in the Echo Mode and depresses the trigger one round is fired, if the target moves, the shooter can move the selector to the safe position and a second round will not fire upon release.

The ECHO AR-II TRIGGER has SEVERAL DISTINCT FEATURES

  • PATENTED Design that gained ATF Approval (Patent # US 8,820,211 B1)
  • Technology licensed through HIPERFIRE inside the Echo Trigger
  • Light, clean, and crisp pull in Semi-Automatic Mode
  • The Echo AR-II Trigger is packed full of cutting edge technology
  • Reliable function in Echo Mode .

The Echo AR-II Trigger is for many of the AR-15 platforms but not all.   The Echo AR-II Trigger NO LONGER comes with a stripped carrier with gas key. Customers made it very clear that they did not want to deal with a proprietary carrier.  FosTecH’s team of engineers developed the Echo AR-II so that it did not need that proprietary carrier.  If you have any questions about the Echo-AR-II trigger please go to  www.echoquestions.com  You can also call our office if you would like to talk to someone in person at 812-445-4028

GEISSELE 308 HI-SPEED NATIONAL MATCH TRIGGER SET

Hi-Speed National Match Triggers
Geissele Automatics currently offers three large pin Hi-Speed trigger products.  These adjustable triggers are specially designed for competition, hunting, tactical, and military use, where both accuracy and robustness are critical. As an adjustable trigger, the first and second stage weight distribution, as well as, total pull weight, over-travel, and sear engagement are all to be tuned to the shooters preference.

The Geissele Service Spring Set
The Geissele Hi-Speed Service is designed for NRA High Power Service Rifle competition. It is an approved trigger for use in CMP sanctioned competitions such as: National Trophy, NTIT and all Excellence In Competition matches. Service Rifle competitions require military-based weapons to meet certain criteria, one of which is a minimum trigger pull weight of 4.5 lbs. Our Service Rifle Trigger includes our exclusive 5-Coil trigger spring which will give a nominal 4 lbs. on first stage. The Service trigger pull weights are biased with most of the pull weight on the first stage. This will allow a light second stage with an icicle-sharp break, effectively giving your weapon a match-grade trigger let-off.

The Geissele DMR  Spring Set
The Geissele Hi-Speed Designated Marksman Rifle is designed for tactical and military shooting where trigger pull weight is not regulated. Perfect for all precision tactical shooting and squad Designated Marksmen, the higher second stage weight helps in high-stress shooting situations.

With very few restrictions, these highly customized semi-automatic weapons are intended to produce extreme accuracy at long range. The Geissele Match Trigger is a perfect Space gun add-on as the pull weight can be adjusted to low levels that enhance trigger control. The fast lock time assists the shooter in getting every ounce of accuracy out of his weapon. The Hi-Speed hammer uses a full-power hammer spring which imparts more kinetic energy into the firing pin, producing much more consistent primer ignition – especially with experimental cartridges or AR 308, 308 AR and AR-10 based weapons.
