I have two FWB 300s set up for BR. I use Mueller 8-32X44 Target Dot scopes. Technically, they aren't springer rated, but the FWB is so gentle it hasn't hurt them. You can get them for around $250 and are excellent scopes in my opinion. I know a number of people that use them for BR and are well satisfied. The glass is excellent for a scope in this price range, plus you have the option to change the magnification to suit your likes. I have mine set at 28X. For serious competition I have Sightron S3 fine cross hair on my TM1000.
