Questions & Answers
Will this work with the SB Tactical PDW brace? And would I need to replace my 9mm bcg or take the extra weight off the 9mm bcg? Expert Answer

NO this will not work with the SB Tactical PDW brace. Since it is set up for only their own CQB series stock and brace kits.

Paired with an hbpdw brace and it works perfectly. I can't speak to longevity of the product as I only have a few hundred rounds using it.

Works perfect by Drew Matterer, March 20, 2018
I love the JP SCS and use them on all my builds. Makes for a really smooth operation of the BCG. I used this one in a LWRC ultra compact buffer tube and stock. The length of the SCS was a little short but I used a spacer behind the SCS and it works p...

If u want a quiet MSR along with a smooth as silk action then this is what you want. Since I bought my 1st one 5 years ago, I have lost track of how many rifles I have with the JP spring. Every build has worked flawlessly and that smooth action still...
