GEN 2 AR-10 Silent Captured Spring Builder with Alternative Spring Pack
Standard Version
Includes partially assembled SCS unit, three alternative weight springs and spacer to allow for installation in both carbine-length and rifle-length buffer tubes.
The JPSCS2-10 is designed to work in standard 7-inch M16/M4-length buffer extension tubes on .308 AR-type rifles like the DPMS LR-308. Armalite .308 rifles, likewise, use these standard M16 extension tubes with rifle-length stocks, so this unit will function normally when installed with the supplied spacer. However, Armalite’s .308 carbines use a slightly longer, non-standard carbine extension tube. The JPSCS2-10 can still be used with these extension tubes by installing the spacer, which must be modified to fit. Alternately, the system will function readily if the longer Armalite carbine tube is replaced with a standard 7-inch .223 carbine extension tube.
The JPSCS2-10 is not compatible with the HK MR762, the Sig Sauer 716, or the Rock River Arms LAR-8 because of its longer bolt stroke and subsequently longer extension tube.

Well designed....So many spring and weight options to get the correct recoil and bolt kick back.....Winter needs to leave so I can go make some noise and check function

I had originally bought a cheaper version(different brand) of “silent capture” but it was not adjustable, wasnt as nice as my jp i had in another rifle, so i broke down and bought this. With large frame ar’s it is important to tune every aspect, it can make a real difference on recoil, accuracy and follow up shots. This kit just makes that easy.

Q: I just finished building a. 308, AR10 with a 24 inch barrel. The gas system checks out but the action is short stroking. The buffer spring seems to be a bit strong. What do you suggest?

Q: So besides the buffer tube that this drops into, are there any other parts required to complete the buffer assembly in your ar 10? And also does it batter what length tube you use?

A: Depending on the setup, you'll possibly need the end plate/castle nut. You can use a rifle tube or a carbine tube as there is a spacer in the kit that you'd insert in the rifle tube configuration.
