AR-15 CARBINE FLAT WIRE SPRING – AR-15 CARBINE FLAT WIRE SPRING

Description

Original price was: $21.95.Current price is: $16.28.

The SI Carbine Flatwire Spring is an economical, easy upgrade to any AR system with a carbine buffer system.  The flatwire spring increases service life of the platform, smooths out the shooting cycle, and greatly outlasts the stock spring.  Increased bolt load, in addition to decreased compression force increases reliability in cycling.  Additionally, all SI Flatwire springs are cryogenically stress relieved to provide greater consistency, longer spring life, and greater resilience to high cyclic rates.   At a cost not much greater than stock carbine springs, the SI Flatwire is an easy option for those either looking to replace worn buffer springs or begin new builds.  
 
Package include:

  • 1x Carbine Length Flatwire Spring

Features

  • Cryo-cycled 17-7 ph steel for strength, reliability and longevity
  • Decreased harmonics lessens system vibration for faster follow up shots.
  • Increased bolt load for more positive feeding
  • Reduces distracting AR "twang"

Frequently Asked Questions

Are these brass cases and reloading components factory-new or once-fired? +

We stock both premium factory-new components and high-quality once-fired brass. Please check the specific product listing title and description carefully; once-fired brass is fully inspected, but we always recommend resizing and inspecting prior to priming and powder charging.

Will this case trimmer gauge or die set work with my progressive press setup? +

Our standard reloading dies and case length trimmer accessories utilize industry-standard threads (typically 7/8"-14) compatible with major single-stage, turret, and progressive presses like RCBS, Hornady, Lee Precision, and Dillon. Caliber-specific trim gauges must match your exact brass caliber.

Do you enforce shipping restrictions on powder, primers, or live ammunition? +

Yes. Non-hazardous reloading equipment (dies, case length trimmers, gauges, and unprimed brass) ships via standard ground carriers with no extra fees. Any orders containing smokeless powders or primers will incur standard federal HazMat handling fees and cannot be shipped via air transportation.

How can I track my shipment to ensure delivery safety? +

Precision reloading gear is valuable, so all orders are shipped with tracking enabled. As soon as your package is dispatched from our inventory warehouse, a tracking number will be emailed to you. You can monitor your shipment directly on our Track Order page using your unique Order ID.

Can I return precision measuring tools or die components if they don’t fit? +

We accept returns on unused, unaltered tools, case preparation equipment, and unopened component boxes within 30 days of item delivery. Due to safety and strict quality control on the reloading bench, we absolutely cannot accept returns on opened packs of primers, smokeless powder, or processed brass casings.
