Description

Long lasting, and having several options for tuning makes Sprinco springs an amazing option for your build.

 

Yellow– Reduced Power Buffer Spring. Sprinco collaborated with two prominent commercial ammunition manufacturers, and two prominent gunsmiths to arrive at the design for the Yellow spring. It’s approximately 20% lighter than the White spring, and was the consensus choice out of 4 different evaluation samples provided to all parties. They all added in their final evaluations that if a particular gun needed a lighter spring, that the gas port should be enlarged for overall reliability. The Yellow spring is also appropriate for with low power SRTA training or SIMS Rounds for training operations.

 

White– Standard Power Buffer Spring. Equivalent spring load to a brand new 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 Mil-Spec load spring without concern for replacement, then this is the one for you. 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. Just consider it as permanent new Mil-Spec spring.

 

Hot White– Intermediate Power Buffer Spring. The Hot White spring came to life as an accident that turned out to be a valuable solution for certain platforms. Sprinco did a production run of White springs where the loads came in perfectly between the design loads of the White and Blue spring, so they sat them aside, and did another run of White springs to the proper load specifications. When Sprinco had some calls from customers wishing for a spring that was in between the performance of a White or Blue spring, Sprinco had them try out the discarded springs on a trial basis, and they turned out to be perfect for their needs, thus, the evolution of the Hot White spring for tuning purposes. If you are among those who are advocates of using Mil-Spec carbine springs rather than tuning to perfection, this is also a good choice in the vast majority of instances to enhance performance.

 

Blue– Enhanced Power Buffer Spring. The design loads of the Blue spring are approximately 15% greater than the White spring for one of the considered Load Constants in the spring design. Sprinco was encouraged to manufacture the Blue spring by Mike Pannone of CTT Solutions, who modified one of their Red springs, and recommended that Sprinco should offer a spring with the loads of the Blue spring to address the high performance demands of other specimen platforms.

 

Red– Extra Power Buffer Spring. This was Sprinco’s first AR buffer spring solution that they were tasked to design back in 2006 for a Force Modernization Team to specifically address spring-related M4 carbine reliability function issues for operating challenges in the Eastern Asia Theatre. The design loads of the Red spring are approximately 25% greater than the White spring for one of the considered Load Constants in the spring design. The Red spring is commonly used in 9mm, 6.8 SPC, 6.5 Grendel, .450 BM, .450 SOCOM, .500 Beowulf, and Colt LE6920’s specimen carbines, but certain specimen guns can deviate from the norm depending upon port values and the power factor of your chosen ammunition loads.

NOTES: The RED spring is appropriate for moderately gassed .308 / 6.5 CM / .260 Rem heavier caliber carbine platforms using AR-10 / SR-25 Pattern (Armalite, LMT, LaRue, KA.C, etc. receiver extensions and 3.25” carbine buffers. NOT for use in “DPMS Pattern”.308 Carbines using standard 7″ deep M4 extension tubes and short, 2.5” buffers. (Use our “ORANGE” Spring” for that specific platform approach application.)

 

Orange– Extra Extra Power Buffer Spring. The Orange spring is much stouter than the Red spring. The Orange buffer spring was originally engineered for the demands presented by.308 / 6.5 CM / .260 Rem, etc., heavy BCG carbine DPMS Pattern applications using standard 7″ Depth M4 extension tubes, and short 2.5″ buffers (Including aftermarket “heavy buffers”) in robustly gassed 16” – 18” ML gas carbine platforms, but has been proven to be a requirement for tuning over gassed carbines of any equivalent heavy calibers in AR-10 pattern tubes with 3.25″ buffers or lesser calibers (5.56, etc.).

 

Green– Standard Power Rifle Length Buffer Spring.The Green spring is for use in A1 / A2 fixed stock rifle length receiver extensions (buffer tubes) with rifle length buffers. It is also extremely popular in intermediate depth (7.75 “ deep) VLTOR A5 buffer tubes with 4” A5 buffers. The spring design loads of the Green spring are those of a BRAND NEW mil-spec buffer spring. While the Green spring is primarily for use with lesser calibers such as .223, 5.56. 6.8 SPC, 6.5 Grendel, 7.62 X 39, etc. in A2 rifle length tubes, it may sometimes be appropriate for use in long BBL (20”+) rifle length gas barrels in heavier calibers such as .308 and 6.5 CM, .260 Rem, etc.. (May not be effective for unsuppressed 7.62 X 51) In the latter scenario, an H2 or H3 carbine buffer has been used successfully in rifle length tubes with the Green spring. Over gassed heavier caliber guns with rifle length tubes may be addressed with our Red or Orange carbine springs and standard length 3.25” carbine buffers along with a spacer to yield the appropriate tube depth for the longer BCG’s.

 

 

 

Additional information

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 (Tubes make great storage compartments for all sorts of gear)
  • Optional Cryogenic Processing Available (Select Item 26001)

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.
