A dual carriageway continues as the A4032 into the centre of Bristol, with a speed limit. The M32 is a trunk road, therefore its maintenance and upkeep is paid for by Highways England, the national roads authority. Most of the road has two lanes in each direction, though an extended sliproad north of junction 2 provides a climbing lane, and the short section between junction 1 and the M4 has three lanes both ways.
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
