MAXIM DEFENSE MD15 PDW Lower Receiver Assembly Mil-Spec BLK

  Intermediate Power - Carbine Length - Buffer Spring The Intermediate Power Buffer Spring is a balance between the design loads of the White and Blue spring. This recoil spring is for use with 5.56 AR-15s with a carbine or mid-length gas system and carbine buffer tube. When we had some calls from customers wishing for a spring that was in between the performance of a White or Blue spring, we had them try out the discarded springs on a trial basis, and they turned out to be perfect for their needs, thus, the evolution of the Hot White spring for tuning purposes. Color Coded RED & WHITE. Features: Intermediate Power - Carbine Length - Buffer Spring Compatible to AR-15 5.56 NATO /.223 REM from 12.5″ to 16″ uppers with carbine or mid-length gas System For carbine length buffer tubes only Made from chrome silicon wire stock Heat treated and shot peened Compatible accessories see under this article, accessories.

Spring will not change performance for many hundreds of thousands of rounds Greater resistance to heat induced performance degradation Reduced cyclic rate with Enhanced or Extra Power springs and reduce / eliminate bolt bounce with optimal spring / buffer weight selection Reduced operating cost as replacement springs are not needed during the life of your upper receiver assembly. Less downtime and fewer trips to the armorer for spring replacement, in fact, this will most likely be the only buffer spring you will ever need for the duty cycle of your carbine or rifle!

  Reduced Power - Carbine Length - Buffer Spring We collaborated with two prominent commercial ammunition manufacturers and two prominent gunsmiths to arrive at the design for the Yellow spring. It’s approximately 20% lighter than the White spring, and was the consensus choice out of 4 different evaluation samples provided to all parties. They all added in their final evaluations that if a particular gun needed a lighter spring, that the gas port should be enlarged for overall reliability. The Yellow spring is also appropriate for with low power SRTA training or SIMS Rounds for training operations. Useful for undergassed rifles, such as some mid-length gas rifles or rifle lenght “Dissipator” 20'' inch builds which is apparent with rifles that short stroke or have weak ejection patterns. Color Coded YELLOW.
