    I ordered the mk23/ ssx23 to m4 adapter. The results were subpar. I feared I had blown $150 on a paperweight. Contacted Tapp and they offered to replace it or refund my money. They were in the process of refining the ssx23 version. Just tested the newest version and am very pleased with the results. It took some time, but ssx23/ ssx303 customers should have no issues going forward. Great customer service. I have the ssx303. Using 0.25g bbs at 100-110psi chrono’s at 348-355 fps.
