The SLC was investigated by Naval Ordnance Inspection staff at Simonstown in West Africa. The weapon was forwarded to the Ordnance Board in London for testing. Upon testing, the bolt would not feed the top round from the magazine, and the weapon had to be loaded by hand. Recoil was higher than expected and threw off the aim to the left. It was concluded that it was not worth developing the weapon any further, and so no improvements to the design were ever made.
