Dirty Bird AR-15 17-7 Stainless Steel Flat Wire Spring

SKU# D086 | by Dirty Bird Industries

Introducing the Dirty Bird AR-15 17-7 Stainless Steel Flat Wire Spring. Buffer springs are often a part that is overlooked when building an AR from the ground up, but a quality buffer spring can prevent "stove-pipes", misfeeds, and ensure popular cycling.

The Dirty Bird Flat Wire Spring will have your AR running at optimum performance and outlasting a standard music wire carbine buffer spring. Constructed from 17-7 Stainless Steel, this buffer spring is crafted for extra abuse and maximum toughness. Finally, a coating of Sandstrom 28A is applied to the spring.

What is Sandstrom 28A?

  • Sandstrom 28A is a laquer-like coating that is used by the Department of Defense.
  • This low-friction coating can be used in adverse conditions from -325 degrees to 300 degrees, when load pressure is over 100,000 PSI.
  • Sandstrom 28A is virtually unaffected by corrosion, acids, oils and degreasers.

Bottom line is this, the Dirty Bird AR-15 Flat Wire Spring is one of the most underappreciated upgrades that you can make to your AR, and will prolong the life of your rifle.
