I am gonna get a short setup with a brace, and @GJM is advising me to consider a LAW folder. I preface with never seeing one in person. I looked at the videos etc and have two reservations. A smaller one is that if it somehow unlocks, the carbine is not operational, unlike side folder AK or SCAR etc. A bigger concern is that the BCG carrier needs that little extension which is simply pushed in and appears to be just a friction fit. If it were to fall out, gun's dead.
I welcome all personal experiences and comments in this regard. I especially welcome any info if this unit has been appropriately tested and accepted (or rejected) by any professional entities.
