Strykers: Prevent N2 Gauge Damage with Simple Fix

Soldiers load 120-milimeter mortar rounds into their Stryker vehicle

All M1129A1 MCV, M1251A1 MCVV and M1252A1 MCVVA1 Stryker mortar carriers have been upgraded with an N2 gauge that allows Soldiers to monitor gas levels in the 120mm mortar’s RMS6-L recuperator.

The N2 gauge helps make sure the cannon functions the way it should. But the gauge is frequently banged up by blunt objects or hard surfaces. A broken gauge makes the recuperator non-mission capable (NMC).

But there’s an easy and inexpensive solution that uses a piece of standard rubber hose to protect the N2 gauge from damage. Simply cut a piece of 1.25-in diameter hose to length and slide it around the N2 gauge.

Be sure the hose rises above the face of the gauge.

If you don’t have a hose that’s the right size laying around, you can order 1.25-in diameter rubber hose with NSN 4720-01-586-7112.
