The HIPERTOUCH® 24 fire-control drop-in is a high performance, high precision, service rifle upgrade that installs in AR-15® and AR-10® type rifles. The HIPERTOUCH® name is short for HIgh PERformance TOUCH and 24 for user adjustable trigger weights between 2 and 4 lbs. It’s the “AR” fire-control upgrade we’ve all dreamed of. For installation and operational features of the HIPERTOUCH® family of AR fire-controls watch the 24 videos above. A helpful read of the FCG Trouble Shooting Guide relates some issues customers will have during and after installation that are easily resolved with attention to detail and common sense. Found in the guide is this graphic, AR-15LowerCavity.PDF. HIPERTOUCH® FCGs may not work in lowers with pivot holes that are outside the MIL-Spec dimensions shown in RED.
The Genius of the HIPERTOUCH® Fire-Control
HIPERTOUCH® FCGs have uniquely solved two problems with stock AR triggers and AR trigger upgrades respectively: 1) High Trigger Weight, and 2) Low Hammer Fall Energy.
Trigger Weight: The real culprit behind high trigger pull weight is high sear impingement force that produces high friction. To get around that, the stock “AR” trigger and hammer mechanical advantage was changed and the toggle spring feature added to reduce the impingement force on the trigger sear. Designers of two-stage products changed the functional location of the primary sear; HIPERFIRE®’s design has not, retaining the stock design’s single-stage simplicity. This is important for when stock triggers are pulled, the hammer cam-action signals hammer fall is imminent. When 2-stage triggers are pulled, the final higher weight stage also signals hammer fall. This can lead to the flinching problem we all know about. Some like to say the better 2-stage triggers have glass rod or candy-cane like breaks to sell the idea that they don’t signal hammer fall. In any case, the HIPERTOUCH® 24 does not signal hammer fall because the trigger weight is constant over the entire stroke.
Hammer Fall Energy: HIPERTOUCH® features the unique toggle spring functionality that reduces trigger weight, but while doing so, it also increases hammer fall energy by over 35% over the MIL-spec stock design and every trigger upgrade in the market. This permits the shooter to ignite hard MIL and foreign primers as well as hard to ignite 22 rimfire ammunition.
HIPERTOUCH® FCGs retain Eugene Stoner’s design of simple elegance while remaining very robust, without the gritty feel. Shooting for high accuracy is no longer an almost impossible chore. It’s no longer necessary to improve the stock performance by manually polishing the high-friction trigger and hammer sear surfaces, where the end result was only marginally better anyway.
Ambitious sportsmen and marksmen have been turning to trigger upgrades with varying degrees of satisfaction. The better replacements have been one and two-stage triggers with fixed final weights ranging from between 2½ and 4¼ pounds with what some have called a glass rod or candy cane trigger break. Some of these devices require factory or user calibration, maintenance, and/or replacement for wear or doubling. Some of these devices also employ reduced power springs, which have compromised reliable ignition for a “dream” trigger weight.
The HIPERFIRE® “AR” accessory response to those shooter’s looking for a single-stage and very much improved, match quality, “AR” trigger upgrade that delivers high performance is the HIPERTOUCH® 24. It nests in unmodified standard AR-15® and AR-10® type lower receivers in the same way as stock “AR” triggers and hammers without having to remove the safety selector. It is comprised of three subassemblies: the trigger, hammer, and toggle, spring groups. All the parts are made from carbon steel alloys that have been hardened for wear and strength. It features exceptionally low trigger weights with smooth pre-travel, a very clean hammer release with no report to break, match action response, and faster hammer lock-up. Only now with HIPERTOUCH® trigger and hammer actions does “AR” trigger “squeeze” have real meaning.
Safety/Selectors: HIPERFIRE® knows of five safety selectors that will not work with HIPERTOUCH® 24 series triggers:
- Seekins Precision Ambi Safety (60 and 90 deg throws);
- V SEVEN HYBRID 3 GUN/SPORT SELECTORS; and
- Elftmann Slide Safety Selector.
- Talon Ambidextrous 45/90 Safety Selector – Tungsten Grey 2 Lever
- BAD-CASS or BAD-ASS Short Throw Safety Selector
HIPERTOUCH® 24 Series Triggers
The frame component of the HIPERTOUCH® 24 FCG that provides the toggle spring system support is designed to ride on the barrel of semi-auto or “MIL-spec” safety/selectors (not full-auto). This permits normal functional rotation of the safety/selector. An aside: when the FCGs are first installed, some users will notice a little grit during rotation, which is a function of the surface finish on the safety/selector barrel. With a few cycles it will smooth out as the frame and safety/selector self polish.
All four ambi safeties listed do not have a large contiguous cylindrical barrel surface like the stock version; two or more channels or a small diameter barrel have been cut into them that accepts the rear of the trigger when pulled into over travel. The toggle spring frame drops into these channels, which not only relieves necessary compression of the toggle springs but may also prevent free rotation of the safety/selector or even cause rotation of the selector during repeat fire as in the number two case above.
HIPERTOUCH® EDT Series Trigger
The Seekins works in 60 deg throw mode in SAFE and FIRE w/o issue. However, in 90 deg throw mode, the trigger will rotate enough to release the hammer. This is because the trigger tail is shorter than MIL/stock triggers and can move up into the exposed Seekins SS slot just enough to release the hammer when pulled.
Other Ambi Controls: The ambi bolt catch on S&W M&P10s interferes with free rotation of HIPERTOUCH® 24 series triggers. Users have simply removed the ambi control and restored proper function of the 24 series FCG.
