Fixed my problem - JP Enterprises Alternate Spring Pack For JPSCS-10

Everyone knows AR-10's can be tricky. I plan on running a suppressor so I wanted an adjustable gas block. I built my AR-10 with a JP Rifle adjustable gas block and Silent Capture spring. I had to run the adjustment all the way out (full gas) just to get the rifle to lock back on an empty mag. I used this spring pack to fix the problem. The lightest spring makes my rifle run great. The only down side is having to spend $40 for a set of three just to use one. I wish I could send the other two back for a refund. Oh well. Anything from JP Rifle is good stuff.
