ShootingSight 2-STAGE MP-5 TRIGGER.\u00a0<\/em> The HECKFIRE, is the first true 2-stage trigger pack for the MP-5, MP-5K, PDW, clones, or other HK 91\/93\/94, G3 pattern based fire control groups.<\/h4>\n

IMPROVED!\u00a0 Now with overtravel adjustment screw.\u00a0 Allows you to limit overtravel of the trigger after hammer release, for improved accuracy.<\/em><\/strong><\/span><\/p>\n

Roller lock actions rock!\u00a0 ShootingSight has designed the ideal 2-stage trigger to match.<\/p>\n

In choosing the best trigger design, we took a cue from the greatest battle rifle ever devised: the M1 Garand.\u00a0 The M1 has a superb 2-stage trigger.\u00a0 It is robust, combat proven, and offers the crispness and accuracy of a two-stage trigger pull.\u00a0 The M1 concept was married with tool steel, CNC machining, and aerospace surface coatings.\u00a0 The result is the HECKFIRE, a 2-stage, semi-only trigger which is robust, smooth, and crisp.<\/p>\n

Features:<\/p>\n

\u00b7 2-stage, giving a predictable razor sharp break.<\/p>\n

\u00b7 3lb first stage, 5-6 lb total pull.<\/p>\n

\u00b7 Fits Ambi, SEF polymer, MagPul, or steel lowers.<\/p>\n

\u00b7 Two sided safety cam, converts ANY lower to an Ambi, but also comes with a Delete cap, if you do not want Ambi selectors.<\/p>\n

\u00b7 Includes a reverse right-side selector.<\/p>\n

\u00b7 Machined from billet tool steel, for superior metal grain structure.<\/p>\n

\u00b7 Housing CNC machined in aluminum and Mil-Spec hardcoat anodized.<\/p>\n

\u00b7 Ultra hard \/ low friction NiB surface coating on sears allows lube free operation in dirty \/ tactical environments.<\/p>\n

\u00b7 Polished and honed sear surfaces for butter-smooth pull.<\/p>\n

\u00b7 Drop in trigger pack is fully assembled.<\/p>\n

\u00b7 Replaces four 922R components with US made parts: Trigger Housing, Trigger, Hammer, Sear.<\/p>\n

COMPATIBLE WITH ALL HK MP5, 91\/93\/94 or G3, or clones.<\/p>\n

Here is an initial video review done by the HK shooting team: https:\/\/www.youtube.com\/watch?v=HnD98qxp2ng&t=161s<\/a><\/p>\n

The updated selector levers work for all lowers and they cover the selector lever hole in the lower so you cannot see the trigger housing through the hole (which is an improvement over the original selector levers). Our kit includes four selector levers: Left, Right, Right-Reverse, and Delete. This allows you to make your gun into: AMBI, or Left-hand only, or Right-hand only.<\/p>\n

Drop-in, no modifications needed.<\/p>\n

Notes:<\/p>\n

    \n
  1. Trigger does NOT include an ejector lever, pivot pin, or ejector spring, as these are caliber specific.\u00a0 You simply transplant these three parts from your existing trigger pack.<\/li>\n
  2. Trigger follows US Manual of Arms.\u00a0 The safety can only be engaged when the hammer is cocked.<\/li>\n<\/ol>\n

    In order to ship to Canada, purchaser needs to select the option for exportation to Canada.\u00a0 By selecting this option, purchaser affirms that he\/she is a Canadian citizen, and agrees that the trigger is for end-use in Canada and may not be re-exported.<\/p>\n

    ADDENDUM: Some of the newer HKs seem to have the shelf for the trigger housing sitting a little low, allowing some up\/down slop to the trigger housing, allowing the trigger housing to sit low, and the hammer does not get pushed all the way down.\u00a0 I have developed a solution that is a jack-plate to raise the trigger housing.\u00a0 Here is a video. https:\/\/www.dropbox.com\/scl\/fo\/tgfs74bymdnssmirjxyed\/AA311a6JfUj8bTHdnxTzy4o?rlkey=np4rn2qynduwvkudcl8albxp2&dl=0<\/p>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
