Anyone tried a JP CSS in a SIG 716?

[Bangarang]

Has anyone tried running a JP Enterprises Captured Spring System (CSS) in SIG 716 Patrol yet? If so, let me know how it works for you.

I have been running two of these in a pair of AR-15s with 20" HBAR barrels and Gen 1 UBR stocks without any issues. One CSS has about 14,000-15,000 rounds on it.

Thanks, Bangarang
