"BLUE Spring”
ENHANCED Power Buffer Spring, Offers improved performance with most
non-suppressed 12.5"-14.5" SBR's,
16" DI Mid-Length BBLS, and all mid-length uppers with adjustable gas
blocks. Best performance is usually achieved using buffers ranging from
ST-2T,
H2, DPMS Extra Heavy Buffer. Will run in 18"+ Length BBL RRA'S with
ST-T2 Buffers. Color Coded BLUE.
“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 "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.
"WHITE Spring" STANDARD Power Buffer Spring. Equivalent spring load to a “fresh” Mil-Spec M4 Carbine Spring.
This spring will perform reliably in any properly configured and maintained 5.56 Carbine, if you wish to
maintain the performance of a “fresh” Mil-Spec load spring without concern for replacement. This is the best
choice for shooters and purists that wish to maintain the performance of most factory supplied NEW Mil-Spec
springs, but do not wish to be concerned with frequent replacement of same or do not have the time or
inclination to seek enhanced performance options. The "WHITE" spring is recommended for 10.0"-11.0" SBR's with H2 Buffers, 1st Gen M&P's, older
RRA's with under 18"+ BBL's, early generation Colt 6920 LE's, 5.56
& 6.8 SPC 7.5"-8.5" BBL Piston Guns with H2 Buffers, with few
exceptions,
most .300 AAC Platforms, longer carbine barrels
using intermediate or rifle length gas, and when training with SRTA
and other low power and light charged “budget” rounds. Color Coded WHITE.
[EXCEPTIONS: With SBR's which are seriously overgassed firing suppressed, (e.g. 10.3" HK 416's), a RED or ORANGE
along with a hydraulic buffer is often used with great success.]
"ORANGE Spring"
.308 M4 CARBINE Extension Tube EXTRA POWER Moly-Plated Chrome Silicon Buffer Spring in Hard Tube (Color Coded ORANGE) [NOTE: Originally Developed for .308 CARBINE Platforms Utilizing Standard 7" Depth M4 Carbine Extension Tubes with Short Buffers. E.G. DPMS/Bushmaster, Etc., but are Often Appropriate for any Severely Over Gassed Carbine of Similar or Lesser Calibers Color Coded ORANGE.
"GREEN Spring" In addition to use in 5.56 Fixed Stock Rifles, “GREEN Spring”
is just the ticket for use in the VLTOR A-5 Stock
System using their appropriate weight buffer for maximum versatility
in tuning almost any upper configuration, running both with or without a
"can".
Color Coded GREEN.
