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
- Color coded red
- Extra power
- Chrome silicon wire stock
- Heat treated and shot peened
This spring is color coded red, indicating it's optimal for use with 5.56 AR-15s running a carbine-length gas system and buffer tube with a 16" barrel. Sprinco has extensively tested this setup and found it also works great with thumper cartridges like .458 SOCOM, 6.5 Grendel, .450 Bushmaster, and more.
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.

Not Heavy Enough for PCC build
by Aaron -
For my personal build, this spring is not even close, to being Heavy Enough, for my 45acp PCC, maybe it will work for you.
Shells going past 3 o’clock
by Ramiro -
Shells going past 3 o’clock the spring well definitely help; It won’t be the only step you’ll need to bring your shells ejecting at 3 o’clock but it’ll help and It’s a really good spring.
Great spring, but not for 12.5" carbine length barrel
by Nick
Great spring, but not optimal for my system:
12.5" BCM carbine length barrel
H1 buffer, also tried standard buffer weight
Wouldn't lock back on last round. Gonna try a blue spring.
