Tele Vue once manufactured a 5" refracting telescope named the MPT, the Multi-Purpose Telescope. It had a fast f/4 ratio, and had an adjustable diaphragm that ranged from f/4 to f/20. Only a small number were made, with the last being kept by Televue to use as a final optical quality control for all eyepieces they make.

Thor-Agena flew for the last time in 1972 when it launched a KH-4B satellite.
The barrel assembly appears to be based on the AK-47. [10] The design would allow soldiers to configure it according to the needs of the missions by changing rifle barrels. [5] The MCIWS uses a gas-operated short stroke piston design, and uses 30-round plastic-type magazines.
