Sprinco Blue Enhanced Power AR-15 Buffer Spring - Carbine

Sprinco AR-15 buffer springs are made from high-quality chrome silicon wire stock, the same material used in applications from Formula One to motor valve springs that can see up to 15,000,000 compression cycles in a single race -- far more than an AR-15 buffer spring will ever see over its lifetime. To retain that strength, Sprinco heat treats, shot peens, and treats each spring with a proprietary formula that preserves spring efficiency for as long as the rifle is owned.

Features:

• For carbine-length buffer tubes and mid-length gas systems
• Color coded blue
• Enhanced power
• Chrome silicon wire stock
• Heat treated and shot peened

This spring is color coded blue, indicating it's optimal for use with 5.56 AR-15s running a mid-length gas system and carbine buffer tube. Sprinco has extensively tested this setup and found it works great with 5.56 AR-15s from 12.5" to 16" barrel length and either a standard or H2 buffer weight.

Sprinco USA manufactures precision recoil springs using the same chrome silicon wire stock trusted in Formula One and motorsport valve springs, engineered to retain their spring rate far longer than a standard AR-15 buffer spring.
