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.
