Unless you already know which spring you need for your rifle, please refer to the following resources before calling for a recommendation. If you call prior to knowing the answer to the specific current performance of your rifle, you will be referred back to this request to provide results. If you haven't built or shot it yet, neither one of us can predict the outcome. If you need to call for a starting place first for a new build without expecting a perfect outcome, then at least you will have a spring that functions as a known load constant. All of our springs are manufactured in the USA under strict adherence to ISO 9001:2015 quality standards, thus you are evaluating performance with a known commodity vs. a spring of unknown strength.
Gas Mass and Springs AR Tuning
Horizontal Case Ejection Trajectory Chart
AR Tuning Video
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.
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 "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. Just consider it as permanent new Mil-Spec spring. Color Coded WHITE.
Reduced Power Buffer Spring. We 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. Color coded YELLOW.
HOT WHITE SPRING
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. We did a production run of White springs where the loads came in perfectly between the design loads of the White and Blue spring, so we sat them aside and did another run of White springs to the proper load specifications. When we had some calls from customers wishing for a spring that was in between the performance of a White or Blue spring, we 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. Color coded RED & WHITE.
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. Refer to provided tuning procedure reference documents prior to calling for recommendations. We were encouraged to manufacture the Blue spring by Mike Pannone of CTT Solutions, who modified one of our Red springs and recommended that we offer a spring with the loads of the Blue spring to address the high performance demands of other specimen platforms. While contemporary internet forum lore leans towards the use of the Blue spring with an H2 or ST-T2 buffer for 14.5 - 16” ML carbines, nothing is set in stone due to the vast range of gas port values in the wild that have come into play since we first entered the arena. Color Coded BLUE.
Extra Power Buffer Spring. This was our first AR buffer spring solution that we 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. Refer to provided tuning procedure reference documents prior to calling for recommendations for use. 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. Color Coded RED.
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.)
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.). Color Coded ORANGE.
Don't clip coils from any of our other buffer springs in order to yield a lighter spring load for DPMS pattern applications. Doing so will result in an unknown spring load and might damage the gun.
NOTES: If your build is yielding a solid 1:30 to 2:00 O'clock ejection trajectory, then start with an Orange spring and tune it with the buffer weight. Empirical evidence has shown a heavier spring and lighter buffer produces better performance than a lighter spring and heavier buffer.
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 BBL’s 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. Our line of enhanced spacers will be available in the 3rd Quarter of 2019. Color Coded GREEN
CONSTRUCTION SPECS: CARBINE & RIFLE BUFFER SPRINGS
Why do we assign "COLORS" to our buffer springs? We have tens of thousands of buffer springs in various stages of enhancement or in inventory in our facility. This practice is beneficial to both you as the end user and for our employees to identify for quality control and fulfillment. We use Dykem® Opaque Metal Staining Dye to color code the springs, (not rattle can spray paint) during the QC and packaging process. This practice has become the standard industry reference for our different springs. Should you encounter fishy looking deals on internet auction sites, please send us an image for product validation, as there have been a very small intrusion of color coded imposters floating around from time to time that to the trained eye, are glaringly apparent from their advertising images and/or descriptions.
