Sprinco M4 AR-15 Extra Strength Carbine Buffer Spring Choose HOT Red/White Intermediate, Blue ENHANCED, Red EXTRA, Orange Power

Sprinco M4 AR-15 Extra Strength Carbine Buffer Spring Choose HOT Red/White Intermediate, Blue ENHANCED, or Red EXTRA Power

Description

Sprinco AR-15 carbine buffer springs are made from high quality Chrome Silicon wire stock which is used in a variety of applications from Formula One to motor valve springs which can see up to 15,000,000 compression cycles in a single race. This makes it the perfect choice for a carbine which will see far less cycles than that over it’s lifetime. In order for this carbine buffer spring to retain its strength, Sprinco heat treats, shot peens, and treats each spring with a proprietary formula that retains spring efficiency for as long as you have your rifle. 

If you have a carbine of any caliber that has a horizontal case ejection trajectory in the 12:30 - 1:15 o’clock range, you won't be able to attain the optimized 4:00 o’clock trajectory with just a spring and buffer selection (mass). You can either install an adjustable gas block or a port resizing device to reduce the gas volume before fine tuning with springs and buffer weight.

Features:

• For carbine length buffer tubes 
• Color coded
• Made from chrome silicon wire stock
• Heat treated and shot peened

The Sprinco "Hot" RED/WHITE 25203 Intermediate Power carbine buffer spring is a great option to improve the long-term reliability of your AR-15.

The Sprinco BLUE Enhanced Power recoil spring is optimal for use with 5.56 AR-15s with a mid-length gas system and carbine buffer tube. Sprinco has extensively tested this setup and have concluded that it works great with 5.56 AR-15’s with a barrel length from 12.5” to 16” and either a standard or H2 buffer weight.

The Sprinco RED Extra Power recoil spring is optimal for use with 5.56 AR-15s with a carbine length gas system and buffer tube with a 16” barrel. Sprinco has extensively tested this setup and have concluded that it also works great with thumper cartridges like .458 SOCOM, 6.5 Grendel, .450 Bushmaster, and more.

The Sprinco ORANGE 308/OVERGASSED AR15 Extra Extra Power recoil spring is optimal for use with .308 AR-10s with a carbine buffer tube and over-gassed AR15 systems. 

SPRINCO ADVANTAGES:

• Increased "lock time" for faster sight recovery and platform stability
• Consistent spring pressure throughout the duty cycle of the spring, resulting in fewer malfunctions related to spring operation (Especially Type III malfunctions)
• Improved & consistent cyclic operation. 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!
• Correct spring selection works reliably, consistently, and virtually indefinitely in all properly built and maintained AR platforms
