Features of RISE Armament BLITZ Drop-In Trigger w/Anti Walk Pins

  • Ultra-fast Quik-Klik reset you can feel and hear for rapid follow-up shots
  • Virtually no creep to help you stay on target
  • Exceptionally crisp breaks like an icicle
  • Hybrid trigger blade that combines the best aspects of curved and flat triggers for incredible comfort, control, and speed
  • Elementary installation simple and fast with no set screws to tighten
  • NoWay Take-up Most triggers allow a degree of movement prior to engaging the sear, but not with RISE triggers. Measurements done on RISE triggers show no trigger take-up before engaging the sear, so trigger movement begins with the pull required to move and actuate the sear to release the hammer.
  • Single-stage, 3.0-3.5-lb. pull
  • Interior parts are S7 tool steel with heavy-hit hardening then black nitride finished for enhanced strength and corrosion resistance
  • LiteMite Hammer Reduces weight while packing a powerful punch
  • Contained in an anodized housing thats machined from a solid block of 6061 aluminum, which is more durable and longer lasting than punch-tin housings to help the trigger perform flawlessly under a variety of conditions
  • Precision machined with handcrafted finetuning
  • Individually inspected
  • Includes free anti-walk trigger pins for secure installation
  • Fits AR-style platforms built to mil-spec dimensions calibers include .223/5.56, .308, 6.5, 9MM, and more, making it an excellent option for PCCs
