Inexpensive riser block - NcSTAR AR-15 Flat-Top Riser-Mount Standard Weaver Base

Bought this to use on a .22 RF trainer with an NcStar red dot AR as a "simulated Aimpoint Comp 3ML. Riser gets sight up to same height as the Aimpoint

Works great in this application but is longer than necessary. Having a 2-3 inch long version would be nice.
Pros: Nicely made
Cons: Locking knobe way to large
