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.

Best buffer system I've used by Dom, Verified Owner, April 1, 2026
Recently build a honey badger clone 300blk. Anyone who's built a 300blk knows the pain you have to go through in order to get it running as smooth as possible with the ability to swap between supers and subs, suppressed or unsuppressed. Matching a bu...
