M32 motorway The M32 was planned to be a key radial link through to the hub of a network of radial and ring roads within a rectangle encompassing Bristol. Other bounds of this scheme were parts of the M4 (north eastern side), the M5 (north western side) and the tidal reaches of the River Avon (south western side), the south eastern side not being defined by landmarks. The motorway was partly funded by Gloucestershire County Council and Bristol City Council, with a 75 per cent grant supplied by the national Ministry of Transport. It was provisionally called the Hambrook Spur or the
M4 carbine Marine Corps Infantry Automatic Rifle testing, the Colt IAR displayed a MRBS of CLASS I/II Stoppages of 952 rounds, with a MRBEFF of Class III Stoppages of 60,000 rounds. An array of firearms accessory makers have offered gas piston conversion kits for the M4. The claimed benefits include less needed lubrication for the bolt carrier group to run reliably and reduced fouling. The argument against it is increased weight and reduced accuracy. The Enhanced M4 uses an articulating link piston operating system. Complicating the Army search for higher reliability in the M4 is a number of observations of M4 gas
