Most Helpful Positive Review The cherry on top...
I built a 300 BLK pistol, and used the JP Enterprises spring assist kit. This is a must-have kit to complement the main unit- in reality, they should package these springs in with the full unit. You cannot fine-tune it without these springs. Once you have the gas port adjustment set as a "coarse" adjustment, use these springs as a "fine" adjustment. Watch how the shell ejects- optimal setting is when the shell ejects at 90 degrees, and you are good to go!

If u invested in the JP SCS and not the extra springs then u could be missing out on a even better and smoother shooting experience. �

Works great

by T, Verified Owner from MS, United States Written on November 2, 2017
Only use if you have a JP Enterprises Silent Captured Buffer Spring. These will increase or decrease you bolt speed if your system needs tweaking. They work great do not throw away instructions they tell you the strength of each spring. The springs are colored coded for easy identification.
