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.
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® 24C 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 4½ 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® 24C. 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.
Additionally, the HIPERTOUCH® 24C also sports the HIPERSHOE® adjustable finger pad, which can be positioned at five (5) different vertical detent locations along the 24C's straight trigger. By changing location, the shooter can further adjust pre-travel and weight within a broader range than without it as desired for even more trigger responsiveness. Also, the adjustable pad lengthens slightly the extension of the finger to the pad with respect to the pistol grip, which alters the feel and dexterity of the finger on the trigger for added comfort and/or control. The trigger can be installed and operated with and without the shoe.
