In 2015, Chris Skidmore, Member of Parliament for Kingswood, launched the Gateway2Growth campaign, which would see a new road running from the M4 at Emersons Green to the A4174.

Urgent works were recommended on the Eastville Viaduct in particular, which had deficient surfacing, barriers and lighting. A speed limit was placed
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
