Lantac USA E-CT1 Single Stage 3.5lb Trigger – Curved

Out of stock

$217.99 Add to cart to see price

Advanced performance meets precision machining and ultra-slick styling in the shape of the new E-CT1™ Single Stage Trigger from LANTAC. The trigger features massive improvements over the original with entirely different sear engagement surfaces that remove creep and deliver a super crisp break. Radically different internal geometry also creates insanely short reset and near non-existent over travel that will greatly decrease split times and give you a big advantage over the competition.

  • The Hammer, Trigger & Disconnector are precision machined from S7 tool steel with a proprietary sear manufacturing process that yields an incredibly smooth engagement surface and all parts are then case hardened before Black Oxide finish.
  • The CNC machined Aluminum cassette has adjustment set screws built-in that allows the user to set perfect pin tension and the trigger can be installed with standard pins or the threaded screw types seen in previous designs.
  • The cassette is Type 3 Hard Coat Anodized Class2 Black and then Laser engraved for identification.
  • Comes complete with Trigger Assembly and Pin Set.
  • Manufactured and assembled according to strict AS9100 aerospace requirements and quality-assured with the latest technology inspection equipment ECT-1’s are designed for use with AR receivers in 5.56/.223 or 7.62/.308.

Geissele Automatics Super 42 Braided Wire Buffer Spring and Buffer Combo

Out of stock

Price range: $80.63 through $111.83

The Geissele Super 42 Spring was designed to improve the function and reliability of your AR-15 pattern rifle. Its unique spring design uses three independent strands of wire, just like the German MG42 Machine Gun. This concept acts as a harmonic damper and energy absorber by allowing the springs to flex separately from each other. This flex helps displace excess energy which decreases the chance of spring failure and assists with making your AR-15 more reliable.

  • Compared to the stock spring, The Geissele Super 42 Spring has a decreased tendency to lose length and force over a given round count. As an added bonus, it removes the annoying spring reverberations (twang) heard and felt by the shooter through the buttstock.
  • The Super 42 Spring has a 15% stronger average return force than the standard buffer spring. This will assist in stripping rounds out of the magazine when operating with a dirty weapon or when using steel-case ammo.

Lantac USA RPS Ratchet Plate System – Castle Nut & Endplate

Out of stock

$63.00

The LANTAC RPS™ Ratchet Plate System removes the necessity to stake castle nuts in place after fitting. It also provides a QD Sling attachment point directly below the buffer tube. It utilizes a one-piece designed ratcheted tooth and arm, machined directly into the anti-rotation plate itself. The enhanced castle nut has an aggressive grip pattern and radially machined grooves that register with the spring-like arm and tooth on the plate, causing the nut to be retained in place. The nut cannot vibrate loose through firing but can be removed through the use of an armorers wrench if necessary. The teeth and grooves are all internally facing so they cannot be accidentally damaged.

  • Mil-Spec QD Sling Point
  • CNC Machined single pass threads.
  • Simple one-piece ratchet locking plate.
  • Protected engagement surfaces that cannot be accidentally damaged when installed.
  • Aggressive Castle Nut grip pattern.
  • Precision machined from 4140 Steel and QPQ Nitride finished.
