Enhanced Buffer Spring

Description

STANDARD Power: 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; best choice for shooters who wish to duplicate the performance of most factory supplied new springs without concern of frequent replacement. The WHITE spring is recommended for 10.0″-11.0″ SBR’s with H2 Buffers, 1st Gen M&P’s, older RRA’s under 18″+ barrels, most Colt 6920 LE’s, 5.56 & 6.8 SPC 7.5″-8.5″ barreled piston guns with H2 buffers, all (known to date) .300 BLK platforms, and SRTA training and other low power and light charged “budget” rounds. Color Coded WHITE. ENHANCED Power: Offers improved performance with most non-suppressed 12.5″-14.5″ SBR’s, 16″ DI mid-length barrels, and all mid-length uppers with adjustable gas blocks. Best performance is usually achieved using buffers ranging from H2, DPMS extra heavy buffer, and ST-2T. Will run in 18″+ barreled RRA’S with ST-T2 Buffers, and some Colt 6920 LE’s. Use of heavier buffers may not be possible with the aforementioned, as well as most uppers with light weight carrier groups. Color Coded BLUE. EXTRA Power: Best option for 16″+ 5.56 barrels with carbine length gas systems and H buffers, 16″+ barreled gas piston guns, *some* suppressed shorties and 9mm, 6.8 SPC, 6.5 Grendel, .458 SOCOM, 450 Bushmaster, .500 Beowulf, and assorted “Thumpers” using standard 7″ depth M4 extension tubes. Color Coded RED. VLTOR A5 & RIFLE EXTENSION: In addition to use in 5.56 Fixed Stock Rifles, the “GREEN Spring” is just the ticket for use in the VLTOR A-5 Stock System using their standard weight (5.2 Oz.) buffer for maximum versatility with almost any 5.56 upper barrel configuration, both with or without a suppressor. We are such huge fans of the Vltor A5 system that we use those receiver extensions exclusively for all Umbrella builds save PDW type weapons. As a result, all of our green springs receive cryogenic processing for a very predictable and uniform performance within the weapon’s operating cycle. This computerized, ultra low temperature process (-320°F) increases the strength and wear life of the parent material through a change in microstructure resulting in less retained austenite and more uniformity in grain structure. Cryogenics effectively combats high stress cyclic rates, premature wear, and shortened spring life. Color Coded GREEN. HOT WHITE: INTERMEDIATE POWER “HOT WHITE” Moly- Plated Chrome Silicon CARBINE Buffer Spring. Color coded White/Red Note: Buffer should be inserted into the color coded end of the spring for fast identification once installed.
