Hi:

I'm new to AR-15s and just built up one with a Spikes Tactical upper flattop with Picatinny rail and it has an A2 front sight. I traded some work with a buddy for an almost new Burris FastFire red-dot (I have one on a Kel-Tec rifle I own and like it). However, I neglected (OK, I'm a newbie) that heighth of the A2 front sight. The red-dot beam is mid way up the sight. Are their mount risers that can elevate my FastFire to level it with the A2 front sight?:)
