They got a lot of things right with this generation - SIG SAUER SBX15 Pistol Stabilizing Brace

This revision got a lot of things right. The overall size and weight has been significantly reduced compared to the GEN 1 version. One change I appreciate the most is that the buffer tube sleeve is completely closed on one end. Also the velcro straps are better designed and fit securely on the unit. The rubber material is very dense, yet lightweight and should provide years of service. On final note, I installed this on a Arsenal SAM7K-03 and it balances out the system without adding bulk or weight.
