CONSTRUCTION SPECS: CARBINE & RIFLE BUFFER SPRINGS:

ASTM Grade A877 Certified Valve Quality Chrome Silicon Wirestock
Heat Treated, Stress Relieved and Dual Stage Shot-Peened post winding (Our springs really ARE shot-peened)
Impregnation / Plating with Re-Micronized Molybdenum Disulfide formulation
Hard plastic tube packaging for protected transport and easy storage
Optional Cryogenic Processing available upon request

ADVANTAGES:

Shortened "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.


"RED Spring": EXTRA Power Buffer Spring, Best option for 16"+ 5.56 barrels with carbine length gas system platforms with standard front sight towers and H buffers, 16" + BBL gas piston guns, *some* suppressed shorties,and later generation Colt LE6920's, 9mm, 6.8 SPC, 6.5 Grendel, .458 SOCOM, 450 Bushmaster, .500 Beowulf, and assorted "Thumpers" using standard 7" depth M4 extension tubes. AR-10 Carbines (E.G. Armalite, Noveske, LMT) using deeper extension tubes and standard length carbine buffers to accommodate the longer .308 BCG also use the "RED" Spring. Please call us to discuss successful historical "recipes" for implementation of the RED spring in .308, 6.8 SPC, etc. RIFLE length extension tube platforms. Color Coded RED. NOTE: NOT for use in .308 Carbines using standard 7" M4 extension tubes and short, stubby buffers. (Use our "ORANGE Spring" below for that specific platform approach application.) NOTE: If you have a seriously overgassed .308 Carbine which has the deeper AR-10 platform receiver extension tube running an H3 buffer firing 175 Gr. Projectiles and / or suppressed, many shooters have experienced success using the "ORANGE" spring, as it is still heavier than a "RED" spring in that application.
