A little comparison - SB Tactical SBA4 Stabilizing Brace for Mil-Spec Carbine Extension Platforms

if you're in the market for a brace, you've probably looked at the sba3 and sba4. imo they each have pros and cons. the sba4 has the nice cheek weld. I feel less recoil with the sba4 than the sba3. it is slightly bigger than its counter. the only thing that makes the sba3 nicer than the 4 is that is more minimalistic. comes with a buffer tube but no spring or recoil buffer
