Today I had a indoor test of the BS 4 with Parabolic adapter on a Unique Alpine UPG-1 in .308 Winchester. The BS 4 was mounted on a picatinny between the Fortmeier Bipod ca 20cm from the Musslebreak. 59 from 60 shots were detected and marked with the green dot and only 1 shot was marker with a red dot. That was a pretty good result. To avoid loosing the parabolic adapter, I secured it with a rubber ring. The speed range was below 8m / sec. Next week I will test it with the SAPR 751.
