I have several braces from various manufacturers and this is by far the best. It is light, simple, and gets the job done. Will be putting these on some upcoming builds. My only feedback is I wish you either made good grips or the grey was a lighter shade. I have it paired with a BCM grip and their grey is significantly lighter.
Works as it should fits perfectly on my carbine buffer so light it's like it's not there.
